Re: gcc-ddc

[Gábor Boskovits]

Hello!

It seems, that one of the source of the reporoducibilty issues with the gcc build output is that it contains la files with libdir recorded.

Libtool records that in those la files.

I wonder if we have any solution to that already, because it seems to affect every project using libtool.

If not, do we have any idea to solve this? It would be great if we could come up with some generic solution to the problem.

Maybe that’s sufficient already.  Since the result of this package is
not going to be used as an input to build software it may not actually
need a wrapper.

Instead we can just set the variables in a build phase.

I would prefix all of the environment variables with “GUIX_GCC_” just to
avoid conflicts with other legitimate environment variables.  Other than
that the names are fine.

Thanks for investigating this.  I’m impressed with your level of success!
