Add support for `mipsel-unknown-linux-uclibc`

CuckooEXE commented 1 year ago

There is built-in support for mipsel-unknown-linux-{gnu,musl} in cross, however, this adds uclibc as an additional stdlib.

I generated the mipsel-unknown-linux-uclibc.config.in file by running ct-ng mips-unknown-linux-uclibc (which is a pre-configured sample), and changed the endian-ness to little.

The Dockerfile.mipsel-unknown-linux-uclibc file is largely based on the docker/Dockerfile.arm-unknown-linux-gnueabihf from the cross project.

CuckooEXE commented 1 year ago

The container builds just fine, but testing doesn't work completely work. @Alexhuszagh gave me the snippet

test() {
  DYLIB=1 STD=1 RUN=1 TARGET=$target \
    CROSS_TARGET_AARCH64_LINUX_ANDROID_IMAGE="ghcr.io/cross-rs/$target:local" \
    ci/test.sh
}

to test with, and this doesn't work. Neither does cross +nightly run --target mipsel-unknown-linux-uclibc on a fresh cargo new project.

The test function gives this output:

+ cargo metadata --format-version 1 --filter-platform mipsel-unknown-linux-uclibc
[cross] warning: `cross` does not provide a Docker image for target mipsel-unknown-linux-uclibc, specify a custom image in `Cross.toml`.
[cross] note: Falling back to `cargo` on the host.

Not sure why it's not finding my local image

Alexhuszagh commented 1 year ago

CROSS_TARGET_AARCH64_LINUX_ANDROID_IMAGE

This part is wrong: CROSS_TARGET_AARCH64_LINUX_ANDROID_IMAGE. It should be CROSS_TARGET_MIPSEL_UNKNOWN_LINUX_UCLIBC_IMAGE. Also, just generally we tend to add a -cross suffix to all our images, just to avoid any conflicts with those in the main repository, since sometimes we have overlap for people who want to use older glibc versions, etc.

Alexhuszagh commented 1 year ago

Once everything works, also please add an entry to the README so people know your target is now supported. Something like

| Target Name                           | Image Name                                  |
|:-------------------------------------:|:-------------------------------------------:|
| aarch64-apple-darwin                  | aarch64-apple-darwin-cross                  |
| aarch64-apple-ios                     | aarch64-apple-ios-cross                     |
| aarch64-pc-windows-msvc               | aarch64-pc-windows-msvc-cross               |
| mipsel-unknown-linux-uclibc           | /mipsel-unknown-linux-uclibc-cross          |

Where the added line is | mipsel-unknown-linux-uclibc | /mipsel-unknown-linux-uclibc-cross |.

Updated the Dockerfile name, but still not getting the test to run properly

I've been busy today, getting to this shortly. I can try to run the tests and build the image myself and see how it goes from there.

Alexhuszagh commented 1 year ago

Fix the above environment variables, update the README to mention the new target, and this is ready for merging. Nice work, thank you.

Alexhuszagh commented 1 year ago

Do you mind if I make some changes directly to this PR? I can fix up some of the stuff with the template file, so it uses the correct placeholders and uses the Rust mirrors instead of relying on third-party broken mirrors (or unreliable ones).

CuckooEXE commented 1 year ago

Apologies for the late response, please make any changes you see fit! I'll be updating based on your earlier comment right now

No worries, you're doing us a favor. Also, I'm currently waiting on https://github.com/cross-rs/cross/pull/1087 to merge, which will make full configuration support for this possible. I've added a sample target for big-endian MIPS uclibc to test this and it fully works:

https://github.com/Alexhuszagh/cross-toolchains/blob/uclibc/crosstool-ng/mips-unknown-linux-uclibc-cross.config.in

I will be giving you co-author credit for that file btw. Once I make my commits, feel free to squash the commits to remove my commits from the history (you don't need to credit me).

CuckooEXE commented 1 year ago

What changes are you making to the configuration file? I already encountered an issue with my own use-case; the embedded device I'm developing for is running libuClibc-0.9.33.2.so, however in my configuration file it's stuck on libuClibc-1.0.31.so.

Do we want to add a configuration variable for changing the version of uClibc that gets compiled?

Only major change is to use the Rust CI mirrors for ISL, rather than another third part source.

Alexhuszagh commented 1 year ago

The other is allowing you to change the uclibc, gcc, and other versions when configuring using placeholders. That needs the above PR to merge the though before uclibc configuration works. But it should then work with pre-1.0 uclibc.

CuckooEXE commented 1 year ago

Ah perfect! Thank you so much for all the assistance with this. I'm looking forward to contributing more at some point :)

Alexhuszagh commented 1 year ago

#1087 is getting merged now, so I'll post the diff for my config file and yours (and show you how to configure it for an older uclibc version):

cargo xtask configure-crosstool mips-unknown-linux-uclibc-cross --uclibc-version "0.9.33.2"

The diff is below. You should just be able to apply it (I think you have to do it in reverse), move it to the crosstool-ng directory, configure it once https://github.com/cross-rs/cross/actions/runs/3291170840 merges, and then it will apply all the necessary changes.

If you notice, there's a few differences: rather than hard-code the versions, we use placeholders (using Windows-style environment variables, since they aren't valid here). For example, we use %CT_UCLIBC_V% and%CT_UCLIBC%rather than the hard-coded versions. This allows us to customize the uclibc, GCC, and Linux versions when configuring. The items indocker/crosstool-configwill use the defaults, but it means you can use a uclibc version of0.9.33.2` just by configuring the above script.

The other is using the Rust CI mirrors for ISL, just to guarantee availability.

So if you can provide a value like that in crosstool-ng and then configure it with the default values, it's ready for merging ^_^.

Alexhuszagh commented 1 year ago

We might also need to provide a config for the mirrors, actually, since uclibc-ng only supports 1.0+, and the original uclibc is pre-1.0. I can do this by auto-detecting the version and determining which mirror to use.

We'll see if this commit https://github.com/crosstool-ng/crosstool-ng/commit/dab2d8011ea67118348a6bd28ae3583960c1b5c3 gets in the way however. We're using 1.24.0, so this shouldn't be an issue. We'll need to modify the following lines I believe:

CT_UCLIBC_NG_PKG_NAME="uClibc-ng"
CT_UCLIBC_NG_SRC_RELEASE=y
CT_UCLIBC_NG_PATCH_ORDER="global"
%CT_UCLIBC_V%
CT_UCLIBC_NG_MIRRORS="http://downloads.uclibc-ng.org/releases/${CT_UCLIBC_NG_VERSION}"
CT_UCLIBC_NG_ARCHIVE_FILENAME="@{pkg_name}-@{version}"
CT_UCLIBC_NG_ARCHIVE_DIRNAME="@{pkg_name}-@{version}"
CT_UCLIBC_NG_ARCHIVE_FORMATS=".tar.xz .tar.lz .tar.bz2 .tar.gz"
CT_UCLIBC_NG_SIGNATURE_FORMAT="packed/.asc"

These should remove the _NG part, so for example, CT_UCLIBC_NG_PKG_NAME becomes CT_UCLIBC_PKG_NAME if using pre-1.0 versions.

Alexhuszagh commented 1 year ago

I'm running into a bug when pushing to this repository. If you apply the following patch then squash the commit history, this is ready for merging. Since the upstream configuration in cross has merged, this works out-of-the-box now. There's still issues with pre-1.0 uclibc, but those are due to sysnum.h issues and the libgcc toolchain for more recent GCC versions, not due to the config files themselves.

Hi! Sorry for the delay, life got a bit busy. I was also waiting for this issue to resolve. Do we still want to have uClibc < 1.0 support considering it might take significant developer effort to actually get it to work?

I'm not sure if we want to adopt the "We support it but it's up to you to get it working" or "We won't support it unless it's (basically) plug-and-play". I guess we could get a single uClibc < 1.0 .config version working and have that be the plug-and-play?

Alexhuszagh commented 1 year ago

For the pre-1.0 uclibc, I think it's fine as-is (that is, it can be configured to work but only post-1.0 is tested), since the original uclibc has been hard-forked and mostly replaced, but I also understand there are cases where you need to use an older libc. I think having a default config file is fine, but a very handy addition would be a README entry for what GCC/uclibc/Linux versions work with pre-1.0 uclibc. We've documented some caveats with some of our crosstool-ng images, but also additional features or working examples would be quite nice as well.

Alexhuszagh commented 1 year ago

Any update on this? If no, I can merge the changes myself and then squash the commit history, give you the co-author, and merge. Is that fine?

CuckooEXE commented 1 year ago

Hi @Alexhuszagh, sorry about the big delay. Unfortunately, some work stuff came up so I'm not sure if I'll have the cycles to do this in the near future. I'd very much appreciate it if you could finish the PR, but if not, I can do it when I'm free again.

Thank you!

No worries, you're making contributions on your own time: thanks for all your work.

@Alexhuszagh Sorry for the mega delay! Committed the diff, let me know if anything else needs to be done :)

Can you squash the commit history? Other than that, everything looks great. To do so (just need to squash it to a single commit on top of 971e8bb), run:

$ git reset 971e8bb
$ git add crosstool-ng docker README.md
$ git commit ...
$ git push --force

This looks incredible.
