Also no change with:

I've tried to cargo clean before cargo test with all of these, and tried with cargo test --no-default-features as well.

Thanks for a cool library, I'm excited to start delving into it. FWIW this was building and testing fine on Windows yesterday :) It looks like there is some active work going on to make this easier on MacOS, so I hope this is more constructive than just adding to noise or confusion.

Further reading:

davidhewitt commented 3 years ago

Right, so if I'm reading this correctly, maturin develop works to build the library. But you are having difficulty running tests.

maturin actually passes the cargo config automatically, but I suspect that the cargo config will cause problems with testing. To confirm, can you try:

Remove the cargo configuration file and confirm maturin develop still builds successfully

Make sure your Cargo.toml looks like this:

  [package]
  name = "foo"
  version = "0.1.0"
  edition = "2018"

  [lib]
  name = "foo"
  crate-type = ["cdylib"]

  [dependencies]
  pyo3 = "0.14.2"

  [features]
  extension-module = ["pyo3/extension-module"]
  default = ["extension-module"]

This is necessary so that we're sure that pyo3's extension-module feature will not be requested when cargo test --no-default-features is run.

Now try cargo test --no-default-features

n8henrie commented 3 years ago

Thank you so much for a rapid response!

Progress! I was able to get the minimal example to test without errors!

I'm still seeing the error: linking withccfailed: exit status: 1 error above in my real use-case though, but I noted that it is now ending with

= note: ld: library not found for -lpython3.9
          clang: error: linker command failed with exit code 1 (use -v to see invocation)

which made me wonder.

Sure enough, I wiped out my virtualenv and created a new virtualenv using system python (I usually use pyenv for projects to keep the python version reproducible) and it then works!

I've tried to wrap this up into a little shell script for reproducibility, named tryagain.sh:

#!/bin/bash

set -Eeuf -o pipefail

pushd $(mktemp -d)

cargo new --lib foo
pushd foo

To learn more, run the command again with --verbose.

It's good to see (via the python3 -c line) that the library is running in all 3 cases!

I've tried re-adding the [target.aarch64-apple-darwin] part to ~/.cargo/config and re-testing, and I see the same behavior -- homebrew python works, system python and pyenv python fail.

I see a similar error mentioned here, but it doesn't seem relevant as I'm running all commands as my current user (no sudo).

Sorry if this is now a separate issue -- I'd be happy to start a new issue if you'd like. Keeping here for now, as it's still giving me what seems like an architecture-specific error when running cargo test.

n8henrie commented 3 years ago

I added export PYO3_PRINT_CONFIG=1 and export PYO3_PYTHON=${BASE_PYTHON} to my script above; ~~it now fails at maturin develop with all configurations (even with homebrew python, which was succeeding previously)~~. For example using homebrew python:

error: failed to run custom build command for pyo3 v0.14.2

EDIT: The problem should have been obvious: -- PYO3_PRINT_CONFIG=1 is set, printing configuration and halting compile --. Removing the PYO3_PRINT_CONFIG and just leaving PYO3_PYTHON restores the prior behavior, where homebrew works and the others don't. Sorry about that.

davidhewitt commented 3 years ago

It's expected for the compilation to stop with PYO3_PRINT_CONFIG=1 - the only way to get output to the user from the PyO3 build script is to stop the compilation.

Looks like system python and pyenv are failing for different reasons.

With ystem python it looks like your setup is not finding the system Python shared library at runtime - you need to make sure your environment is setup appropriately to do this, maybe these resources can help with that:

With pyenv it looks like the python shared library isn't being found at link time. Can you use PYO3_PRINT_CONFIG with that configuration and check the lib_dir which the config reports? There should be a libpython3.9.dylib in there, I guess...

Yes, your response beat my edit. Your error message was very obvious, sorry I missed that.

messense commented 3 years ago

I usually install Python from pyenv using PYTHON_CONFIGURE_OPTS="--enable-shared" pyenv install X.Y.Z which doesn't build the Python.framework thing and never encountered this kind of issues.

n8henrie commented 3 years ago

With regards to the pyenv failure, it looks like it's because I've installed my pyenv pythons with the --enable-framework flag (which I had to do to allow linking to some of the MacOS libraries IIRC).

I just tried adding --enable-shared, and I get:

configure: error: Specifying both --enable-shared and --enable-framework is not supported, use only --enable-framework instead

n8henrie commented 3 years ago

For pyenv, I tried adding to the script

export LD_LIBRARY_PATH=$(dirname "${BASE_PYTHON}")/../Python.framework/Versions/3.9/lib

which correctly maps to the folder containing libpython3.9.dylib, but it still fails with:

 = note: ld: library not found for -lpython3.9
          clang: error: linker command failed with exit code 1 (use -v to see invocation)

I then tried with a folder containing libpython3.9.a, also no luck:

export LD_LIBRARY_PATH=$(dirname "${BASE_PYTHON}")/../Python.framework/Versions/3.9/lib/python3.9/config-3.9-darwin

I then found this issue and so tried

export LD_LIBRARY_PATH=$(dirname "${BASE_PYTHON}")/../lib

which failed with the same error.

EDIT: (I added a line immediately after to ls "${LD_LIBRARY_PATH}" to confirm I got the path right in all cases.)

davidhewitt commented 3 years ago

As far as I know LD_LIBRARY_PATH is a runtime rather thank link-time thing, so I'm unsuprised that didn't help.

Can you dump the contents of python -m sysconfig for one of your pyenv installs? I would be curious to know if there's some configuration PyO3 can use to resolve this case, or whether it looks like it's always going to need user help to supply the right library path.

davidhewitt commented 3 years ago

It looks like maybe there is no python3 framework with which to link on big sur?

It's possible. What does /System/Library/Frameworks/Python.framework contain? There's definitely no 3.x version in there?

(I think with the system python you did link successfully to something, so it should just be a case of finding the library (lib_dir from PYO3_PRINT_CONFIG?) and using LD_LIBRARY_PATH to include that at link load time)

n8henrie commented 3 years ago

As far as I know LD_LIBRARY_PATH is a runtime rather thank link-time thing, so I'm unsuprised that didn't help.

I exported it at the beginning of the same script above, which does everything from virtualenv creation to maturin develop to cargo test --no-default-features, so it should be present at runtime as well. Right?

It's possible. What does /System/Library/Frameworks/Python.framework contain? There's definitely no 3.x version in there?

    PYTHONFRAMEWORKINSTALLDIR = "/Users/n8henrie/.pyenv/versions/3.9.6/Python.framework"

This one's interesting. Can you show me where libpython is located inside that directory?

Also, it looks like dumping sysconfig for your system Python might also reveal where the Python framework is configured for that python too?

Thanks for your time with this!

Can you show me where libpython is located inside that directory?

I think this shows it: https://github.com/PyO3/pyo3/issues/1800#issuecomment-900483765

Also, it looks like dumping sysconfig for your system Python might also reveal where the Python framework is configured for that python too?

Yep, so running with LD_LIBRARY_PATH=/Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.8/lib will probably resolve issues with your system Python.

it should be present at runtime as well. Right?

Yes, but the error we've been seeing with pyenv is that it can't find the library to link (the wrong LIB_DIR is being detected by pyo3 to add to the linker search paths), and so LD_LIBRARY_PATH helping to load the library at runtime never comes into play.

Looking at your pyenv sysconfig, I think that pyenv should really have LIBDIR set to /Users/n8henrie/.pyenv/versions/3.9.6/Python.framework/Versions/3.9/lib/? It could be worth reporting this upstream with pyenv and see whether they agree it's a bug.

In the meanwhile, you can probably workaround this by using PYO3_PRINT_CONFIG to get the current pyenv configuration, save that to a file, replace the lib_dir to be set to that directory above, and then use PYO3_CONFIG_FILE environment variable to point pyo3 at that custom lib dir.

Thanks for all the suggestions. Still getting this with the system python; will need to take a closer look later. Thanks again for your time!

This worked for pyenv. I would not have figured that out. Thank you!

I'll see if I can put something coherent together.

Right, sorry, I'm misreading. If I understand https://blog.krzyzanowskim.com/2018/12/05/rpath-what/ correctly, we need to ensure that the RPATH in the final binary contains this framework dir.

Maybe something like this could work, to add the Xcode frameworks dir to the binary?

Well, more weird findings.

With both the system python and pyenv, I can run the same e.g. BASE_PYTHON=/path/to/pyenv/python tryagain.sh script from above, and it fails with the same error as above.

However, if I take a line from the end of the error output and cd into the tmpdir it is using, e.g. /private/var/folders/kb/tw_lp_xd2_bbv0hqk4m0bvt80000gn/T/tmp.RpYiD4RYF0/foo/target/debug/deps/foo-52886a903c6e12a4 -> cd /private/var/folders/kb/tw_lp_xd2_bbv0hqk4m0bvt80000gn/T/tmp.RpYiD4RYF0/foo and then cargo test --no-default-features from there -- it works.

Which doesn't make sense to me, because I am executing the command from that directory in the script (pushd there). (To be sure, I changed the pushd to cd, and it still fails.)

Homebrew python continues to work without having to manually cd to the tmpdir.

Why would that be?

Even worse, my actual project still fails with the same error I started with, even with running from that directory: note: ld: library not found for -lpython3.9 -- but it works if I clone into a tmpdir, cd there, and then run there. I've tried cargo clean, rm -r .venv, opening a new shell to make sure no ghost envvars are hanging out, even mving the old directory and re-cloning. I'm sure this is something simple I'm overlooking, but I'm pretty bewildered. Why would it fail when run from the tmpdir in the script, succeed when run from the tmpdir interactively, and fail when run from ~/git, where I keep all my projects?

This sounds like it's definitely an environment issue. Are you using direnv or something similar which automatically loads python environments as you switch directories by any chance?

However, if I take a line from the end of the error output and cd into the tmpdir it is using,

It doesn't look like you're selecting a python interpreter when you do this, so the subsequent cargo test probably ends up recompiling with homebrew python, which we know works well.

my actual project still fails with the same error I started with, even with running from that directory

Which python is that with? Presumably we now expect it to work with homebrew python and require manual environment overrides if you use system / pyenv.

n8henrie commented 3 years ago

Doh! That was it. Sourcing the venv after cd and it fails as expected. It wasn't obvious to me (though should have been from your patient replies in this thread) that running cargo test --no-default-features would be pulling in runtime information from my python venv -- I figured that all happened during a python command like maturin develop.

I'd really prefer to use pyenv for development, since it pins the python version (i.e. when 3.10 comes out soon and homebrew updates it might hose any of my venvs that are based on homebrew python). For the time being, exporting the PyO3 config, manually editing the config file to fix the LIBDIR issue, then running the below to automatically export PYO3_CONFIG_FILE upon venv activation seems workable.

$ echo "export PYO3_CONFIG_FILE=\"$PWD/pyenv-config.txt\"" >> ./.venv/bin/activate

Maybe something like this could work, to add the Xcode frameworks dir to the binary?

Using /usr/bin/python3 for venv, install_name_tool does the trick:

$ source ./.venv/bin/activate
$ readlink -f $(which python3)

davidhewitt commented 3 years ago

😅 does this mean we now solved all the cases? 🚀

n8henrie commented 3 years ago

I'm not sure I'd consider the system python case fully resolved -- yes, it seems like the pyenv case is an upstream issue.

For the MacOS system python3, the general process above was a little clunky:

Copy a dynamic library path to python3, surprisingly buried somewhere in Xcode
search for a dynamically named binary towards the end of a bunch of error output
running a somewhat obscure tool to change the @rpath
profit

I'm still doing some reading and found a few posts like this, I wonder if I can add some linker args to Cargo.toml to make this process smoother for other MacOS users (with a planned documentation PR). Or perhaps some build.rs magic. Or perhaps another option to help this be a little smoother before I'd consider the issue solved.

I am profoundly grateful for your time on this issue so far!

davidhewitt commented 3 years ago

Fair enough. If you come across something which is reusable and can be shoved into a build.rs we can add it as a new API in pyo3-build-config for users to invoke in their build scripts.

n8henrie commented 3 years ago

Relevant conversations:

Tried a bazillion or so cross-product combinations of:

adding to cargo config:

[profile.dev]
rpath = true

maturin develop --rustc-extra-args='-C link-args=-Wl,-rpath,/Library/Developer/CommandLineTools/Library/Frameworks'

maturin develop --rustc-extra-args='-C link-args=-Wl,-rpath,/Applications/Xcode.app/Contents/Developer/Library/Frameworks'

$ DYLD_FALLBACK_LIBRARY_PATH=/Library/Developer/CommandLineTools/Library/Frameworks cargo test --no-default-features

Just as I was about to give up, I hit gold:

$ RUSTFLAGS='-C link-args=-Wl,-rpath,/Applications/Xcode.app/Contents/Developer/Library/Frameworks' cargo test --no-default-features

Seems like that's all that's needed, I removed the rpath = true and it still works.

I prefer /Library/Developer/CommandLineTools/Library/Frameworks to the Xcode path above, and it seems to work as well, though there are a lot of differences between the two (according to diff -r).

POC:

#!/bin/bash

One way to make this a little easier is the same virtualenv trick as per above:

$  echo "export RUSTFLAGS='-C link-args=-Wl,-rpath,/Applications/Xcode.app/Contents/Developer/Library/Frameworks'" >> ./.venv/bin/activate

Probably a better solution is to put in ./.cargo/config:

[build]
rustflags = [
  "-C", "link-args=-Wl,-rpath,/Library/Developer/CommandLineTools/Library/Frameworks",
]

With regards to build.rs, I thought this looked promising, but no dice:

fn main() {
    println!(
        "cargo:rustc-link-search=framework=/Library/Developer/CommandLineTools/Library/Frameworks"
    )
}

But using nightly (for testing only, looks like it has been stabilized to be released with 0.56) and using this build.rs worked a treat:

$ cat build.rs
fn main() {
    println!(
        "cargo:rustc-link-arg=-Wl,-rpath,/Library/Developer/CommandLineTools/Library/Frameworks"
    );
}

Works just as well with /Applications/Xcode.app/Contents/Developer/Library/Frameworks (instead of the CommandLineTools path).

Phew!

Once cargo:rustc-link-arg is available in stable rust, would it be reasonable for me to submit a PR to PyO3's build.rs ~L110, with some logic looking for /Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework in lib_dir, and if found, emit the rustc-link-arg above? I would probably stick to the Xcode path, since that's the one contained in LIBDIR:

$ /usr/bin/python3 -m sysconfig | grep '\bLIBDIR\b'
        LIBDIR = "/Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.8/lib"

Well, it fixes the pyenv issue at least! No more need for dirty environment variable hacks, nice that a build.rs can get placed in git (~~though perhaps I should figure out some dynamic way to set the homedir~~ I guess PYENV_ROOT will work for now).

$ cat build.rs

Once cargo:rustc-link-arg is available in stable rust, would it be reasonable for me to submit a PR to PyO3's build.rs ~L110, with some logic looking for /Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework in lib_dir, and if found, emit the rustc-link-arg above? I would probably stick to the Xcode path, since that's the one contained in LIBDIR:

Hmm, this an interesting one.

Modifying binaries' RPATH for all downstream users may have unintended consequences; they may suddenly start loading a different shared library to what they were before.

I found an interesting blog at https://www.mikeash.com/pyblog/friday-qa-2009-11-06-linking-and-install-names.html#comment-0a8da6a6e71853ed6f96a0d58e77627f which suggests that /Library/Frameworks and /System/Library/Frameworks are searched by default.

I think the macOS Python installer from python.org will install a framework into /Library/Frameworks? So I wonder whether users typically will not run into the rpath issue you're having with the system (aka XCode) Python 3.

This problem seems to be unique to the environment you're running: you're using the XCode Python which wants to supply its linkage through an rpath, however there's no matching Python3 framework in your system's installed libraries.

This is why I think a pyo3-build-config API which users can use to opt-in, rather than changing it by default for everyone, seems preferable to me?

Modifying binaries' RPATH for all downstream users may have unintended consequences; they may suddenly start loading a different shared library to what they were before.

With a default Big Sur installation, apparently /usr/bin/python3 is a stubfile that prompts users to use the MacOS Command Line Tools to install the version I've discussed above at /Library/Developer/.

My wife's MacBook Air seems like a decent test case (she is not a developer, but has MacOS Command Line Tools installed so that I can run automated backups). Unfortunately, it looks like there's more to the story. Instead of the @rpath error from above, I'm getting one more similar to the pyenv error (she does not have pyenv installed).

  = note: ld: warning: directory not found for option '-L/Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.8/lib'
          ld: library not found for -lpython3.8
          clang: error: linker command failed with exit code 1 (use -v to see invocation)

For her, it looks like /Applications/Xcode.app doesn't exist at all, so it's a bit frustrating that it's still set as LIBDIR according to python -m sysconfig. /Library/Developer/CommandLineTools/Library/Frameworks does exist. Neither the build.rs nor RUSTFLAGS from above works alone; instead, I have to both set RUSTFLAGS='-C link-args=-Wl,-rpath,/Library/Developer/CommandLineTools/Library/Frameworks' (I didn't install nightly on her computer, so I can't yet try the build.rs approach for fixing rpath), and I have to also set the build.rs as per below.

fn main() {
    println!(
        "cargo:rustc-link-search=native=/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/lib"
    )
}

Again, on her MacBook, LIBDIR is identical to mine, even though she doesn't have XCode installed, which seems like an upstream Apple issue I guess?

$ /usr/bin/python3 -m sysconfig | grep '\bLIBDIR\b'
        LIBDIR = "/Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.8/lib"
$ ls -ld /Applications/Xcode.app
ls: cannot access '/Applications/Xcode.app': No such file or directory

What a pain.

you're using the XCode Python

I didn't install anything special via Xcode, and as shown above one doesn't even need to have ever installed Xcode to run into this, it's just the default MacOS system python3, installed via MacOS Command Line Tools.

I wonder whether users typically will not run into the rpath issue you're having

I guess that's a good question. I don't know how common it is for MacOS users to install Python through Python.org, as opposed to homebrew or pyenv, which is what I've always done. I had thought /usr/bin/python3 might be more common than via Python.org, but I could be wrong.

Either way, given that we've gone through several not-terribly-onerous workarounds:

export PYO3_CONFIG_FILE
install_name_tool
export RUSTFLAGS
.cargo/config
build.rs

perhaps this could start as a documentation PR and go from there?

davidhewitt commented 3 years ago

Ah ok, thanks for testing all that! Agreed it looks like there's a bit of oddity in the way that Apple's set this up.

I think a documentation PR is an excellent idea. I've actually been wanting to add a section to the guide for a while on installing Python. I think there's two separate topics, though that's not necessarily the best way to organise it:

what's needed to be configured to be able to build an extension module
what's needed to be configured to be able to embed the interpreter (including running tests as attempted here)

I was hoping that we'd be able to break those two down by OS and installation method. (E.g. the information that we've collected here is a perfect example of the different choices available for macOS.) E.g. something like the alacritty install notes which cover lots of platforms. We can start with something simple (macOS / Linux / Windows) with plenty of gaps, and invite users to fill in information for their platform.

(Doing any documentation on this line would probably supercede #763 which never got merged.)

n8henrie commented 3 years ago

Somehow I missed this section in the docs: https://pyo3.rs/v0.14.4/building_and_distribution.html#macos

It doesn't seem like pyo3_build_config::add_extension_module_link_args() makes any difference for /usr/bin/python3 in my case, which makes sense since it says that maturin should be doing this for me.

n8henrie commented 3 years ago

Good new: with some help from the pyenv team, I found a different way of approaching the framework install that seems to have things working without any extra steps (build.rs, linker flags, etc.).

The short of it is that CONFIGURE_OPTS, which is what I was using, is working differently than PYTHON_CONFIGURE_OPTS (https://github.com/pyenv/pyenv/issues/2081). With PYTHON_CONFIGURE_OPTS, the --enable-framework build flag is working and seems to be properly setting prefix, so while LIBDIR is unchanged, rust is finding everything as expected.

https://github.com/pyenv/pyenv/issues/2038#issuecomment-931728391

So I think only the system MacOS installation remains an issue, and it certainly seems buggy based on the above.

sobolevn commented 3 years ago

Is there any way to solve this?

I've just got hit by it:

I am using MacOS and this setup:

[dependencies.pyo3]
version = "0.14.5"

[features]
extension-module = ["pyo3/extension-module"]
default = ["extension-module"]

Update: https://pyo3.rs/v0.14.4/building_and_distribution.html#macos

digizeph commented 2 years ago

I hit the problem with m1 Mac when trying to publish a crate original built fine on intel-based machines.

I was able to resolve the issue by adding --no-default-features flag.

this helped me: https://pyo3.rs/v0.14.2/building_and_distribution.html#macos

xloem commented 2 years ago

This issue is present on android termux as well as macos.

sorry, my error is different, deleting this comment error happens only with maturin build, not maturin develop: "attempted to link to Python shared library but config does not contain lib_name"

[oops, I don't see a way to delete comments, apologies]

websearchers: the workaround here is to make a custom config file as described at the bottom of https://github.com/PyO3/pyo3/issues/1800#issuecomment-902539210

davidhewitt commented 2 years ago

@xloem if you're able to share a repro in a separate issue we might be able to understand why the lib name is missing and perhaps avoid the need for you to have a custom config eventually.
