libgccjit and gccemacs

libgccjit and gccemacs

[Formbi]

Hello!

I'd like to make gccemacs work in Guix. Joseph LaFreniere made this libgccjit package:
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=40045
and I made this: https://termbin.com/06cmr

When I try to build gccemacs, I'm getting errors like this:
ld: cannot find crtbeginS.o: No such file or directory
ld: cannot find -lgcc
ld: cannot find -lgcc
libgccjit.so: error: error invoking gcc driver

This seems to be connected to this problem:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87808
but I don't know how to fix this. I tried adding gcc-toolchain to inputs
of libgccjit and gccemacs, but it didn't help.

Hi Formbi,

I'm quite ignorant on guix but the libgccjit error is potentially
related to the LIBRARY_PATH value.

Here a nice description of what libgccjit expects to find in that
respect:

https://gcc.gnu.org/onlinedocs/jit/internals/index.html#environment-variables

Hope it helps.

Best Regards

Hello Andrea, Formbi, and Guix,

I got gccemacs and the no-x version to compile. They do not run
entirely correctly and the closure size is quite large. That said, it
feels snappy!

I submitted patches to issue 44775: https://issues.guix.gnu.org/issue/44775

If someone could investigate the retained closure references and
missing references to the store, that would help a lot!

Thanks and good luck,

John
