I highly recommend building this package in a clean chroot. This avoids the use of a AUR helper, which sometimes uses /tmp as the stating directory, which often gets filled completely by gcc's build process.

It also provides a clean environment, which minimizes interactions between your current environment and gcc's build process.

Error making: gcc6 (gcc6-libs gcc6)

@L1ghtmar3 your link is broken. Could you please to force-rebuild without parallel make?

I'm having trouble building gcc6 on a fresh system, either using yay or manually. Full build log, though I don't think it contains any actual error messages, and seems to end on slightly different lines every time. The line after that was build aborting due to Error 2 in Makefile at line 917.

This might have something to do with my makepkg.conf CFLAGS="-march=native -mtune=generic -O2 -pipe -fstack-protector-strong -fno-plt". When I could build the package successfully on my other machine, the flags were rather default -march=x86-64 and so on. The -march=native description for the PC that fails the build.

I hadn't noticed that this package was back in AUR. Let me know if you need a hand maintaining the package. -- Joey

A make distclean in src/gcc-build solved the issue.

Builds fail reproducible on my machine in the bootstrap comparison step between stages 2 and 3:

@dviktor https://0x0.st/zcUP.txt

@moham_96 Can you please post your error log?

Does this package build ok for you guys ? It fails for me in build()

@dviktor The website is reset now, it's working, before that, it was 500 http status.
