Description

Hi

I have attempted to build and install stdlib using fpm build --profile release but get the following error message:

cd stdlib
git checkout stdlib-fpm

I am running on a new Apple computer using Apple Silicon M1 CPU - which maybe the cause? I have run into other build errors previously to do with REAL issues - so it maybe the same problem?

For reference in case it helps: urbanjost/M_strings#2

Thanks for any help / advice!

Expected Behaviour

That stdlib builds OK using fpm using gfortran on macOS arm64.

Version of stdlib

Current version obtained using the steps document above.

Platform and Architecture

macOS (arm64) Apple Silicon M1 Big Sur version 11.6

Thanks a lot @wiremoons for reporting. kargl did warn us about this. 😄

Thanks @milancurcic and @Romendakil for the feedback, and for linking those other issues. I will keep en eye on them for now out of interest, and will re-try once a fix is available. No rush - just glad it is being looked at, and a fix is being considered. A good insight into all the hard work that goes on in the background that is not always apparent or noticed by users like me!

@milancurcic @awvwgk Is there a specific issue in fortran-lang/stdlib about data-mining of iso_fortran_env? I couldn't find one. I started something but some advices would be nice ;)

There is #485 about documenting the currently available data kinds.

The main issue here is that our tests currently use all kind parameters directly, therefore we first need a mechanism to conditionally skip tests if a kind parameter is not available. Using preprocessor in the tests is a bit tedious right now, which was the motivation to refactor the tests.

Thank you @awvwgk

The main issue here is that our tests currently use all kind parameters directly, therefore we first need a mechanism to conditionally skip tests if a kind parameter is not available.

I wrote a small Fortran program that scans iso_fortran_env and creates stdlib_kinds.f90, and common.fypp. Based on these, it should be quite easy to conditionally create tests.

Using preprocessor in the tests is a bit tedious right now, which was the motivation to refactor the tests.

I am not sure why it is tedious right now: fypp is already used for the tests.

Defining the preprocessor manually in every manual makefile and CMakeLists.txt, setting the flags again and including the preprocessor command is quite tedious. A lot to take care of to get this running smoothly in CMake and the makefile, especially the make clean requires some extra thoughts. Now with the fpm export there it got worse because the fypp preprocessed tests are currently ignored.

Makes my head ache when having to think about all those things for using the preprocessor in the tests. I personally prefer to do the cleanup first and have more confidence in the stability of the testing infrastructure.

Edit: I opened a couple of issues for the individual aspects which could be improved to make fypp easier usable for testing.

Ok. I understand your point, and partly agree with it.

Data-mining iso_fortran_env will also lead to issues with how fpm currently handles stdlib.

Should we consider removing qp from stdlib until we can reliably support it?

I was thinking about that too. At least it would allow its use on a wider range of platforms.

There is now staged branch which allows to disable quadruple precision support in CMake builds, see #565 for details.

However, there is an issue with removing the quadruple precision via fypp preprocessor macros, since it becomes permanent once we preprocess to the stdlib-fpm branch, whether to support quadruple precision in the fpm version is a decision we have to make when deploying the branch in the workflow. If we explicitly disable the generation quadruple precision routines we will get a minimal fpm compatible version of stdlib which also works on MacOS/Arm64.

A dynamic solution would require retaining the preprocessor macros in the stdlib-fpm version, however the user has to be explicit about enabling or disabling support for those by adding --flag "-DWITH_QP=0" (this is what I'm doing in test-drive at the moment). For stdlib this would mean we need a two-stage preprocessing, first using fypp as meta-programming tool and than the preprocessor of the Fortran compiler to create guards depending on features we want to enable. The practical drawback of this approach seems huge to me.

Enabling fypp support in fpm is only a partial solution, since it adds the fypp requirement to using stdlib with fpm.

@awvwgk I quickly look at #565 and it sounds good.
Regarding stdlib-fpm, why not generating two branchs: stdlib-fpm (minimal version without qp) and stdlib-fpm-qp (with support for qp). So the user may choose which branch is the most suitable for his project (e.g., my computer supports qp, but I never use it. Therefore, I would prefer to use a minimal version, especially for reducing the compilation time).

@wiremoons @certik I don't have access to MacOS/Arm64, if you have time could you give the patch in #565 a try (you need fypp installed)?

The CMake build should work directly, for the fpm build you have to deploy the fpm version locally first using:

bash ci/fpm-deployment.sh
fpm build -C stdlib-fpm

By default I'm currently deploying a minimal version, no quadruple precision, maximum rank 4.

Hi @awvwgk
Thanks for the work you are doing to try and fix this.

I have tried the patch for #565 using the following steps (which I hope is what you needed to see):

git clone https://github.com/fortran-lang/stdlib
cd stdlib
git pull origin pull/565/head
sed -i -e 's/njob="$(nproc)"/njob="$(sysctl -n hw.physicalcpu)"/g' ci/fpm-deployment.sh
bash ci/fpm-deployment.sh
fpm build -C stdlib-fpm

NB: the above sed command is needed as nproc is not included with macOS so it is replaced with the equivalent command sysctl -n hw.physicalcpu to ensure the fpm-deployment.sh can be run successfully.

The outputs of the above two command you requested I run are as below.

Awesome, I think we are close. The problem is now in test-drive rather than stdlib (see fortran-lang/test-drive#7), I will update the defaults in test-drive to match the stdlib fpm deployment. But this also means that deploying two fpm branches would be an issue, because the quadruple precision branch requires to pass through a flag to the testing framework with --flag "-DWITH_QP=1".

Seems like something we also have to figure out for fpm (opened fortran-lang/fpm#609).

I just pushed an update for test-drive, you can just purge the stdlib-fpm directory and redeploy the fpm version to see whether that worked out as expected.

Be good to get it working with just fpm eventually, as per the new issued opened etc. This is great to be able to build, and then hopefully be able to use stdlib on macOS arm64 for the first time.

I have re-run as reported in full above, so is a clean attempt again. No need for the sed step now as the fix you have kindly added for 'nproc' works fine.

The output is looking much better - thank you!

Thanks for testing, that's a tricky one, so far we got away without changing the exports of modules. I pushed another commit to fix this module in #565.

Also, for better testing I set qp = -1 in case the WITH_QP is false, this allows to test it on other platforms than MacOS/Arm64 as well, i.e. when we deploy the fpm version in our CI workflow, to ensure we are not breaking anything again in the future.

No problem testing - glad I can do something to help.

Re-run with a clean clone of stdlib and new clean patch application, same commands as before. Think it building fine now?
