sys-libs/glibc-2.32-r7 cannot compile as the stage2 gcc libraries have undefined symbols related to @GLIBC_2.33. Reproducible: Always Steps to Reproduce: 1.Bootstrap on Arch Linux with glibc-2.33 while Gentoo has glibc-2.32-r7 2. 3. Actual Results: I tried bootstrapping prefix on Arch Linux with glibc-2.33 today again, and I cannot emerge sys-libs/glibc-2.32-r7 in stage3 of the bootstrap. The emake fails with the following error messages: /cvmfs/software.dumont.ca/2021.02/compat/linux/x86_64/tmp/usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: /cvmfs/software.dumont.ca/2021.02/compat/linux/x86_64/tmp/usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/libstdc++.so: undefined reference to `fstat64@GLIBC_2.33' /cvmfs/software.dumont.ca/2021.02/compat/linux/x86_64/tmp/usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: /cvmfs/software.dumont.ca/2021.02/compat/linux/x86_64/tmp/usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/libstdc++.so: undefined reference to `lstat@GLIBC_2.33' /cvmfs/software.dumont.ca/2021.02/compat/linux/x86_64/tmp/usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: /cvmfs/software.dumont.ca/2021.02/compat/linux/x86_64/tmp/usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/libstdc++.so: undefined reference to `stat@GLIBC_2.33' collect2: error: ld returned 1 exit status make[2]: *** [../Rules:218: /cvmfs/software.dumont.ca/2021.02/compat/linux/x86_64/var/tmp/portage/sys-libs/glibc-2.32-r7/work/build-amd64-x86_64-pc-linux-gnu-nptl/support/links-dso-program] Error 1 make[2]: Leaving directory '/cvmfs/software.dumont.ca/2021.02/compat/linux/x86_64/var/tmp/portage/sys-libs/glibc-2.32-r7/work/glibc-2.32/support' make[1]: *** [Makefile:471: support/others] Error 2 make[1]: Leaving directory '/cvmfs/software.dumont.ca/2021.02/compat/linux/x86_64/var/tmp/portage/sys-libs/glibc-2.32-r7/work/glibc-2.32' make: *** [Makefile:9: all] Error 2 It seems that the stage2 gcc gets the latest versions of these symbols from the host glibc: objdump -D /cvmfs/software.dumont.ca/2021.02/compat/linux/x86_64/tmp/usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/libstdc++.so | grep GLIBC_2.33 a71e0: ff 25 0a 2f 1c 00 jmp *0x1c2f0a(%rip) # 26a0f0 <fstat64@GLIBC_2.33> a88b0: ff 25 a2 23 1c 00 jmp *0x1c23a2(%rip) # 26ac58 <lstat@GLIBC_2.33> a8c00: ff 25 fa 21 1c 00 jmp *0x1c21fa(%rip) # 26ae00 <stat@GLIBC_2.33> Is the fix simply to wait that glibc-2.33 lands in the Gentoo overlay?

Thanks Joey, do you have the build.log of sys-libs/glibc? That will tell the root cause of this bug.
Oops, sorry, forgot to link it: https://drive.google.com/file/d/1mBeEDBxno8g6fRnrOE6LdB9VxWj7Hb2J/view?usp=sharing It's 20MB large, so unfortunately it needs to be externally linked.
So, the stage2 libstdc++ picks up symbols from the host libc that are not in the libc version that we are trying to boostrap.

I'm not sure what the fix is. I've been reading online that glibc doesn't really support bootstrapping an older glibc from a newer one. Maybe statically linking the stage2 libstdc++?
I tried the workaround in https://bugs.gentoo.org/702342#c13, as I thought the issue was similar, but I got the same error.
There's only one fix, and that is using glibc-2.33. (It'll go into ~arch soon.)
Thank you, that's what I suspected when I first opened the bug report. I was hoping there was some kind of magic to fix it. Should I confirm that bootstrap works as expected when 2.33 lands on ~arch before we close this, or do you want to close it now?
Error is reproducible on my Artix Linux machine as well.
