Hi! This is the friendly automated conda-forge-linting service.
I just wanted to let you know that I linted all conda-recipes in your PR (recipe
) and found it was in an excellent condition.
Upps Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
This is the CircleCI build. Also attached the log file.
There are a few patches in the AnacondaRecipes version that we may need.
The main thing seems to be we are missing the USE_OPENMP="1"
environment variable setting as suggested here https://github.com/xianyi/OpenBLAS/issues/218
Looks like issue ( https://github.com/xianyi/OpenBLAS/issues/579 ).

Think those are the patches that we added to build on Windows. We should already have all of them. Is there one you see we are missing?
Notably the build.sh looks quite different
https://github.com/AnacondaRecipes/openblas-feedstock/blob/master/recipe/build.sh#L7-L8
https://github.com/AnacondaRecipes/openblas-feedstock/blob/master/recipe/build.sh#L23
https://github.com/AnacondaRecipes/openblas-feedstock/blob/master/recipe/build.sh#L35
This commit ( https://github.com/AnacondaRecipes/openblas-feedstock/commit/a6b3811fa6e3196a97bb385cf6e9a6ec5527d449 ) looks promising.
Would discourage using OpenMP here as Python multiprocessing
uses forking, which is known to cause segfaults with GOMP. The error one gets is very unfriendly (program crashes randomly). One could produce this simply by importing numpy
and then forking.
Yeah, was also reading that. Either trying to disable TLS or using that patch is a good idea. Possibly both.
guess we need both
Hi! This is the friendly automated conda-forge-linting service.
I wanted to let you know that I linted all conda-recipes in your PR (recipe

Here's what I've got...
For recipe:
meta.yaml
, though. To get a traceback to help figure out what's going on, install conda-smithy and run conda smithy recipe-lint .
from the recipe directory. Hi! This is the friendly automated conda-forge-linting service.

Thanks for exploring this Marius. 😄
Raised issue ( https://github.com/xianyi/OpenBLAS/issues/1766 ) to see if we can set USE_TLS=0
in the future.
Is it possible to add a test for the fork issue? I'd be tempted to apply @njsmith's patch for libgomp here instead, Nathaniel, can you comment on this idea if you have time please?
It might be checking whether USE_OPENMP
is defined instead of its value. Leaving it undefined may fix it.
Wouldn’t the patch need to go in the GCC build? Does it still apply cleanly?
I haven't looked at that patch in years, so no idea if it still applies cleanly. Also, does conda even distribute its own openmp runtime libraries? I thought those were part of libgcc or something...
conda does distribute its own libgcc ....
Also, does conda even distribute its own openmp runtime libraries?
Yes, 'AD' provides its own in the libgcc-ng_linux-*
packages.
@isuruf Can you help this poor recipe out?
This shouldn't affect windows
