Running MacOS 14.3 Sonoma and wasn't able to install epigrowthfit (or TMB from source).

Attached, please find the R console outputs from installation (with Rsession info at the top). Makevars and Makeconfig pasted below. Thanks for any tips!

Does this help at all https://github.com/RGLab/Rtsne.multicore/issues/2#issuecomment-300259543 ? (OpenMP enabled in compilation but maybe not found in load library path?)

jaganmn commented 9 months ago

@mikeroswell It seems like you obtained your R 4.3 binary from CRAN. In that case, you should not be using tools, libraries, or headers obtained from a Homebrew distribution. Doing so is bound to infect your .libPaths() with incompatible R package binaries.

My advice is to delete your existing Makevars, remove all packages installed from sources using that Makevars (or, to be safe, all packages in your user library), then start over following the instructions here which should be valid for R 4.3 even on macOS Sonoma. These recapitulate the instructions at https://mac.r-project.org/ which are maintained by the same person who maintains R for macOS. (The latter are the primary source, but include information about building R itself from sources that you don't really need.)

Sorry if the above seems extreme, but it is to me the best way to unmuddy the water here. I'm happy to join a call to walk you through the steps if needed.

mikeroswell commented 9 months ago

@jaganmn , I might take you up on your offer to walk through steps in real time soon, but first I'll ask for a bit more asynchronous troubleshooting.

I got partway:

> dyn.load("omp_test.so"); invisible(.Call("omp_test"))
OpenMP threads available: 10

But still got similar errors installing Rcpp, TMB from source.

Do I need to remove some Homebrew library installations from my $PATH? Where / how would I want to do that (if so)?

I found ~/.zshrc and /etc/profile and deleted homebrew stuff from $PATH. I checked /etc/paths and don't see it there.

jaganmn commented 9 months ago

Yes, good catch. Homebrew is still masking the native C/C++ compilers on your PATH. R CMD CONFIG CC and R CMD CONFIG CXX should corroborate that.

I don't remember how Homebrew sets PATH. Have you also checked the files under /etc/paths.d?

mikeroswell commented 9 months ago

I just checked those, nothing looked like it was a brew installation. If you have suggestions on next steps or want to try to do this in real time, lmk! Thanks so so much, @jaganmn

jaganmn commented 9 months ago

I just tried installing Homebrew. It installed entirely under /opt/homebrew and asked me to run a script to append 2 lines to my ~/.bash_profile and set PATH in the current shell process. Just removing the 2 lines from ~/.bash_profile does not revert PATH in the current shell process because ~/.bash_profile is only run at startup. But if I exit the current shell and launch a new one, then in the new shell PATH is "normal" (without Homebrew).

So my expectation is that you should "only" need to modify your ~/.zprofile (if you use zsh) and restart Terminal.

If Homebrew remains on your PATH after all of that, or if your PATH is fixed but the compilation errors persist, then I'd want to see the (new) output of R CMD INSTALL.

mikeroswell commented 9 months ago

Thanks Mikael. PATH seems brew-free but still having TMB installation issue. latest_TMB_install.txt

mikeroswell commented 9 months ago

And latest_Rcpp_install.txt Rcpp**

jaganmn commented 9 months ago

Another guess, before you give up and ask R-SIG-Mac:

Uninstall your very new version of Xcode and then install Command Line Tools for Xcode 14.3.1 which is what I am using and closer to what CRAN used to build the R binary that you installed. The manual says:

Installing source packages which do not contain compiled code should work with no additional tools. For others you will need the 'Command Line Tools' for Xcode and compilers which match those used to build R ...

So we should comply.

mikeroswell commented 9 months ago

Well, I can't do that with this version of macOS; I'll post to the mailing list.

bbolker commented 9 months ago

A 14000+-line error log is impressive ...

jaganmn commented 9 months ago

Oops, mental lapse ... The compatibility is in the other direction: I can install Xcode 15 on macOS Ventura. Perhaps if I do that then I will be able to reproduce the errors. I will experiment (later).

jaganmn commented 9 months ago

So we are seeing preprocessor errors like

/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/v1/cstddef:46:5: error:
      <cstddef> tried including <stddef.h> but didn't find libc++'s <stddef.h>
      header. This usually means that your header search paths are not
      configured properly. The header search paths should contain the C++
      Standard Library headers before any C Standard Library, and you are
      probably using compiler flags that make that not be the case.

emitted from headers like cstddef in the macOS 14.2 SDK bundled with Xcode 15.1.

cstddef includes stddef.h and expects the preprocessor to find the version of stddef.h in the C++ Standard Library. But the preprocessor is finding the version of stddef.h in the C Standard Library. That suggests that we are prepending to the header search path a directory that contains (but really shouldn't contain) stddef.h.

The culprit, judging from the command line in the Rcpp installation output, would be one of these directories:

/Library/Frameworks/R.framework/Resources/include
/opt/R/arm64/include
/usr/local/include

The most likely candidate in my mind is /usr/local/include, because /usr/local is a standard installation prefix and would have been used by Homebrew on Apple silicon before it introduced support for native installations under /opt/homebrew.

Hence @mikeroswell may need to sudo rm -rf /usr/local/* if he sees Homebrew remnants there and especially if he sees that /usr/local/include contains stddef.h and other headers from the C Standard Library ...

mikeroswell commented 9 months ago

Working now!

I removed lots of stuff:

sudo rm -rf /usr/local/*
 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)"
sudo rm -rf /opt/homebrew
sudo rm -rf /usr/local/Homebrew

Then I reinstalled the GNU FORTRAN comnpiler, openMP, and R.

Then, I installed the R packages Rcpp, Matrix, and TMB from source.

I was then able to install epigrowthfit.

Thanks for all the help, @jaganmn !

mikeroswell commented 9 months ago

@bbolker , Should I in some way close this issue or do other housekeeping? It seems like the upshot was: one way around my issue was to remove all the homebrew installations and try again; I feel like someone encountering epigrowthfit in the wild cd take a long time to discern that from this thread...

jaganmn commented 9 months ago

I'm in the process of updating the README. I'll add a note mentioning perils with Homebrew. I think that we can leave this issue open for future installation problems.

I'll just add that you can use Homebrew to manage your software. You just need to make sure that your Homebrew stuff doesn't infect your R stuff if you've obtained R from CRAN. Don't install under /usr/local with Homebrew (non-issue now that Homebrew installs under /opt/homebrew on Apple silicon) and don't use Makevars to involve Homebrew in R package installation.

davidearn commented 9 months ago

After the README is done, I might upgrade my OS to Sonoma and check the instructions are adequate. It is good that it was possible to get everything to work, but having to obliterate /usr/local/* is a huge pain. We don't want users to have to do that in order to install epigrowthfit.

jaganmn commented 9 months ago

It is an issue primarily for people who have decided to install LLVM and mask Apple's Command Line Tools, i.e., not really unique to Sonoma. The README will mention that Homebrew users can start with brew uninstall llvm, but that won't catch all of the ways that the user could have contaminated their search paths. It doesn't need to be too comprehensive, though, because ultimately CRAN will provide binaries for Windows and macOS.

bbolker commented 9 months ago

Another possible solution/assistance for installers will be to use r-universe to provide binaries ...
