Zig cc dynamic C lib runtime error on NixOS

Help

It might be bug in zig cc, as clearly you are passing -lblas -lgsl -lgslcblas to the compiler but it ignores blas and gslcblas. Does clang behave the same way btw?

Thanks, good idea! clang $(pkg-config --libs --cflags blas gsl) src/main-gsl.c && ./a.out prints the expected

I guess now I need to debug zig. I had this on my list anyways, so will look into it.

@Cloudef FYI and to close the loop here as well, please see GSL dependency cblas in nix flake - Help - NixOS Discourse for further analysis and the resulting upstream issue zig build-exe should not strip indirectly needed libraries · Issue #23215 · ziglang/zig · GitHub.
