 K900 | Why is this important? | 11:35:54 |
| 陈浩南 | I am trying to make intel fortran compiler working on NixOS 25.05. It used to work on NixOS 24.11, but now on 25.05, the intel fortran compiler complains could not find gcc installation directory. | 11:37:32 |
| K900 | What is the package name? | 11:37:41 |
 Grimmauld (migrated to @grimmauld:m.grimmauld.de) | just you wait until you realize stdenv.cc and gcc14Stdenv.cc are different yet again | 11:38:25 |
| 陈浩南 | The Intel compilers is not packaged in nixpkgs. It defined here https://github.com/CHN-beta/bscpkgs/blob/master/pkgs/intel-oneapi/2023.nix | 11:39:05 |
| 陈浩南 | So why? | 11:39:16 |
| 陈浩南 | Where is the code that make difference? | 11:39:32 |
| Grimmauld (migrated to @grimmauld:m.grimmauld.de) | some wrapping magic deep in stdenv, but probably not relevant to your issues anyways | 11:40:14 |
| 陈浩南 | in top-level.nix I saw the definition of gcc:
default-gcc-version = 14;
gcc = pkgs.${"gcc${toString default-gcc-version}"};
| 11:40:21 |
| K900 | Yeah it's not relevant | 11:40:45 |
| K900 | Post the full build log please | 11:40:49 |
| 陈浩南 | Currently Intel fortran compiler ifx works when compiling hdf5 and openmpi, but does not work when compiling VASP (a proprietary software, its source code is only available after purchase, so I could not provide it here).
ifx complains:
ifx: error #10417: Problem setting up the Intel(R) Compiler compilation environment. Requires 'install path' setting gathered from 'gcc'
| 11:46:03 |
| K900 | Does it provide any more information than that? | 11:46:35 |
| K900 | If not, you might just have to strace it or something | 11:46:41 |
| K900 | But either way this is extremely unlikely to be a stdenv issue | 11:46:48 |
| 陈浩南 | No. I will do it another day. Thank you for your answer. | 11:53:57 |
