It’s cheating! ;-) Could you investigate and see whether/how tests could run in the build environment? A common problem wrt. networking in host name lookups. In the build environment, only “localhost” can be found. > The second problem was that pkg-config wouldn't find c-ares, so it > kept on building without it. In that case, I would do this: guix build -K aria2 # … build fails cd /tmp/nix-build*aria2* source environment-variables pkg-config c-ares --libs (Replace “c-ares” with the name corresponding to the actual .pc file provided by c-ares.) It might be that this command fails because of a missing dependency that the .pc file requires. Ludo’.
