It does not build for me in a clean chroot. I get the same error as @adfjjv. It looks like there are some patches in the comments. Can someone more savvy than I update the PKGBUILD.

Doesn't compile, needs to be patched

@midori: I've been playing with that just yesterday, and compilation has finished ok, so I guess my adaptation attempts could be alright, here:

Hello adfjjv. Sorry, can you please explain me how to apply your fix? Also, in the link you shared, the patch that I have to download is the one commented by Joseph Myers?

The aforementioned problem is due to glibc 2.30 https://patchwork.ozlabs.org/patch/1136271/ I've attached the fix.

make[4]: *** [Makefile:449: sanitizer_platform_limits_posix.lo] Error 1

Sorry for the late response zurozuro and cpuheater. The glibc 2.28 issue is fixed in gcc5 5.5.0-3.

Same issue here. The reason is that the function ustat was removed in glibc-2.28: https://lists.gnu.org/archive/html/info-gnu/2018-08/msg00000.html

There's an AUR package for glibc-2.27 which installs into /opt/glibc-2.27/ but I couldn't figure out yet how to compile with this custom glibc. Probably the easiest approach would be to modify the glibc-2.27 package such that it replaces the system's glibc.

I have encountered problem compiling gcc. Any ideas?

It fails to compile for me after about 20 minutes of compiling, which is pretty far into it since I have a 6 core/12 thread Xeon with 64 GB of DDR4 ECC and I'm compiling in /tmp

configure output, since the comments section destroyed the formatting: https://hastebin.com/

After looking at line 907 in the Makefile, it's apparently failing during the final stage of compilation. "The target built for a native non-bootstrap build"
