Hello! Mark Wielaard <mark@klomp.org> writes: >> Also, for the description, please use full sentences.

Sorry for the nit-picks, but the description still starts 'mid-sentence', i.e. "A collection ..." instead of "elfutils is a collection ...". If you think it's better this way I'm fine with that, it's just that elfutils will "stand out" compared to its neighbours at e.g. <https://guix.gnu.org/packages/E/page/3/>. :-) > Yes.

Thanks for the detailed clarification. Re: dlopen, we typically patch in the absolute file names to avoid surprises on foreign distributions (and getting deterministic results in general), so we should probably do it here too. >> Previously 'mesa' was using our other 'libelf' package, but I switched >> it to elfutils in commit 9b3b4c05a06bb8ef22350706b66043b5e93d8d66 >> because that's what "everyone else" do.

I think a single :bin output with all the executables is fine. Regarding separate :libelf output, I suppose just copying libelf.so* should do the trick. Maybe we need to adjust some pkg-config files too? I can look into this if you like. > I'll go ask around here how to create a minimal package to see if that > helps. Although it feels a bit odd.

If we are to use this libelf for 'gcc', we'll need to find a way to avoid the extraneous inputs to avoid complicating the bootstrap graph too much. We can always ignore the build system altogether and roll our own command line for the GCC variant though. Thanks, Marius
