Please read the AUR wiki page before reporting issues.

If you are experiencing a build issue then ensure you are not using an AUR helper and are using a clean chroot.

The only use case for provides=gcc is so you can have gcc9 installed and not gcc. Still doesn't work because gcc9 does not provide the unnumbered executables gcc g++ and various lib, include and man folders. gcc9 is incomplete without gcc.

@tallero provides gcc is not needed, gcc9 can be installed alongside gcc and pkgbuilds need to be configured to use gcc9

Missing gcc in provides for gcc9.

Try it now. The problem is that the compiler links to the system libicuuc.so, which can only link to the system libstdc++.so.6, not the compiler provided libstdc++. I didn't bump pkgrel because the old compiles still work.

I'm not terribly familiar with the AUR system so I can't comment on any of that (I'm building from source directly), but the build issue seems to be due to a bug in GCC's build system. See https://gcc.gnu.org/pipermail/gcc-help/2022-July/141791.html for an explanation and a link to a patch for the source tree. I've yet to finish building successfully, but it fails a lot later with that patch, and my remaining issues might well be down to not yet passing anything but --prefix to configure. Hope this helps someone.

ETA: I also had to patch in https://github.com/gcc-mirror/gcc/commit/2701442d0cf6292f6624443c15813d6d1a3562fe to make it build.

I'm still getting the 'GLIBCXX_3.4.30' not found error as of 12/26/2022 that has been reported over the last few months. I tried using @bialy solution using docker image base-devel-20210418.0.20194 but that isn't working either not sure how he managed to get it to work.

Same issue with GCC10 - https://aur.archlinux.org/packages/gcc10. It seems that there is a problem with one of the building stages if too 'new' compiler is installed in the OS. For me it is GCC12.2.

I was able to build GCC9 using docker image base-devel-20210418.0.20194. GCC packages seems to work after installation on the host OS.

Same here:

.cache/yay/gcc9/src/gcc-build/x86_64-pc-linux-gnu/libstdc++-v3/src/.libs/libstdc++.so.6: version `GLIBCXX_3.4.30' not found (required by /usr/lib/libicuuc.so.72)

My system libstdc++ has the symbol:

$ strings /usr/lib/libstdc++.so.6 | grep "^GLIBCXX_3.4.30" 
GLIBCXX_3.4.30`

But the one that the package brings does not:

$ strings .cache/yay/gcc9/src/gcc-build/x86_64-pc-linux-gnu/libstdc++-v3/src/.libs/libstdc++.so.6 | grep "^GLIBCXX_3.4." | sort -u
..
GLIBCXX_3.4.27
GLIBCXX_3.4.28

The error is when creating the archive, so it could be that it's mixing system libraries with built libraries. It's possible that libstdc++ at the time of gcc9 didn't have that version and some rogue library (from the system) does and requires it, thus the error.

I don't know enough about the GCC build system to know what's wrong in the PKGBUILD, though.

I am trying to build package in a clean chroot makechrootpkg -c -r $CHROOT, but at the end I am receiving this

msgfmt: /build/gcc9/src/gcc-build/x86_64-pc-linux-gnu/libstdc++-v3/src/.libs/libstdc++.so.6: version `GLIBCXX_3.4.30' not found (required by /usr/lib/libicuuc.so.72)

When installing gcc9 I see that it provides gcc9-libs, however it doesn't seem to provide a lib32-gcc9-libs (and there doesn't seem to be another package for this). Is there a known way for me to modify the PKGBUILD in order to build with support for using gcc -m32 with this gcc9 package? Or a different package that I am missing?
