I really would like to get the ML situation on Guix spiffed up but there are some obstacles that need to be addressed (namely around bootstrapping, of course.)

Sounds great to me. :-)
That is what I do, like in my mlton package.

Re: gfortran seems to require gcc-toolchain
Hi Marius, >>> With your patch, I can compile Fortran programs in an environment >>> containing nothing but "gfortran", so I'd say it works! Not quite, in fact. What I had tested successfully is compiling a Fortran file to a .o file. Linking .o files into an executable still fails: /gnu/store/wzia23i6ngqaaz0kd2il7s30758dxvca-profile/bin/ld: cannot find crt1.o: No such file or directory I had to add glibc to my environment to get an executable. So it seems that compiling Fortran programs requires gfortran + binutils + glibc. Cheers, Konrad.
Re: gfortran seems to require gcc-toolchain
Hi Marius and Konrad, IMHO, the average Fortran programmers do not play with "as" and they want "Just Works(tm)" as expected, because they are mainly programming Scientific stuff -- I am not sure the average Fortran programmers clearly understand what the program "as" does. Maybe a "gfortran-toolchain" package with all the battery included? All the best, simon

I'd prefer a compiler that works at 291.5 MiB to a compiler that doesn't work at 238.0 MiB. When you know how to fix the problem (by installing binutils), it's perhaps just a convenience. If you don't know, it's a show-stopper. I see the point of wanting to use a different 'as', but are there any concrete alternatives in Guix that someone might wish to substitute? Personally I have never cared much about 'as'. It's a necessary tool but also a very boring and predictable one. I don't see what I could gain by replacing it. Cheers, Konrad.

On second though, the patch increases the size of 'gcc' from 238.0 MiB to 291.5 MiB. It may also make it difficult to use a different 'as' executable. So I'm not sure whether the added convenience is worth it. Thoughts? signature.asc Description: PGP signature

gfortran seems to require gcc-toolchain
Hi Guix, I am trying to recompile old Fortran code under Guix. I made an (pure) environment containing "gfortran" plus a few required tools (make etc.), but found that every Fortran compilation stops with an error message complaining about "as" missing. Installing gcc-toolchain fixes the problem. If gfortran cannot be used without gcc-toolchain, shouldn't gcc-toolchain be a propagated input of gfortran? Cheers, Konrad.
