I have been able to compile adding this patch:

@KarlLudwig please include it in a future release (if you have plans to do so), thank you.

@KarlLudwig I get this error during build configuration:

Re: /build/gcc12/src/gcc/libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cpp:441:31: error: invalid application of ‘sizeof’ to incomplete type ‘__sanitizer::termio’

It's a breaking change in glibc 2.42.

I might take this opportunity to change to using the tarball release, as gcc 12 is end-of-life at this point, so no 12.5.1 release will ever exist that would warrant using git. Just patches borrowed from gentoo.

Should be updated in a few hours, let me know if anything else breaks.

After almost 3 hours of build time, I finally get:

/home/USERNAME/.cache/yay/gcc12/src/gcc/libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cpp:441:31: error: invalid application of ‘sizeof’ to incomplete type ‘__sanitizer::termio’ 441 | unsigned struct_termio_sz = sizeof(struct termio); | ^ make[4]: *** [Makefile:616: sanitizer_platform_limits_posix.lo] Error 1 make[4]: Leaving directory '/home/USERNAME/.cache/yay/gcc12/src/gcc-build/x86_64-pc-linux-gnu/libsanitizer/sanitizer_common' make[3]: *** [Makefile:533: all-recursive] Error 1 make[3]: Leaving directory '/home/USERNAME/.cache/yay/gcc12/src/gcc-build/x86_64-pc-linux-gnu/libsanitizer' make[2]: *** [Makefile:420: all] Error 2 make[2]: Leaving directory '/home/USERNAME/.cache/yay/gcc12/src/gcc-build/x86_64-pc-linux-gnu/libsanitizer' make[1]: *** [Makefile:18195: all-target-libsanitizer] Error 2 make[1]: Leaving directory '/home/USERNAME/.cache/yay/gcc12/src/gcc-build' make: *** [Makefile:25582: bootstrap] Error 2 ==> ERROR: A failure occurred in build(). Aborting... -> error making: gcc12-exit status 4

And plenty of other errors within the entire build process!

It would be nice if there was something here explaining what's going wrong, and how to deal with it, like one of those "Manual intervention needed" notices.

Sorry but I have no clue what any of this means, but something tells me the build should have thrown up an error and aborted much earlier in the build, seeing that multiples of the same errors were throughout the build.

I read the comments below mentioning "flex" but also that it's needed to install stuff from the AUR which I do and have quite often, and so cannot see that it's the problem.

Sorry but more frustrating than a failed build is having no info on why anywhere to be found.

/build/gcc12/src/gcc/libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cpp:441:31: error: invalid application of ‘sizeof’ to incomplete type ‘__sanitizer::termio’

In a clean chroot environment, I am getting /build/gcc12/src/gcc/libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cpp:441:31: error: invalid application of ‘sizeof’ to incomplete type ‘__sanitizer::termio’

The reason it uses git is because that's what it was when I adopted it. Also, gcc13 and the official gcc14 and gcc do too.

I would also like to know why this is using git instead of tarball releases.

@europrimus flex is part of the base-devel group, which is expected to be installed when building any package (AUR or otherwise).

I have got a fatal error gengtype-lex.cc
I have installed flex in order to build without error.
