@mjklemm Any guesses here? I don't know anything about Fortran. |
|
Hm. That's interesting. Does |
|
@mjklemm flang/module/iso_c_binding.f90 is the closest thing we have |
Ok. Thanks for checking. That means for some reason, Flang is not compiling iso_c_binding.f90. I will try to replicate this on my machine today. |
|
I have tried to replicate this with a recent SHA on main and my development system. I only see an issue with GOLD having trouble: However, all I could try this in a Docker container to more closely resemble your environment. Would it be possible to provide me with a container or at least some more information on how I should build it up? |
|
@mjklemm about your build issue, I had it before. Here is the workaround: my build env is a debian testing. |

When I did the below in a Debian container, it worked for me, too: root@0ae71c2ea53c:/build# find . -name \*.mod

I have merged a potential fix. Please have a go and let me know if it resolves the issue. |

I think it is now fixed. I am blocked on #91819 but a different issue. |

Thanks for confirming! Happy to help! |
