I already built successfully LFS-7.2 on a PowerPC G4 with ALFS. I am

I get the same error when I try to compile the test program. This is
the output when using the “-v” option with gcc:
bash-4.3$ $LFS_TGT-gcc -v dummy.c

There are a number of options, which are not in the vanilla book
(target_alias, --no-create,...). Do you use a customized version of the
book? I guess it is necessary for ppc. I wonder what you have for
replacing the instructions on the gcc page starting with "for file in
gcc/config/{linux,i386/linux{,64}}.h". I guess there might be files
mentioning ppc in gcc/config, which are not touched by the instructions
in the vanilla book. I think the issue is there...

The missing libs do exist on my system:
bash-4.3$ ls -l $LFS/tools/lib/crt*
-rw-r--r-- 1 lfs users 3084 Sep 20 11:16 /mnt/build_dir/tools/lib/crt1.o
-rw-r--r-- 1 lfs users 2024 Sep 20 11:16 /mnt/build_dir/tools/lib/crti.o
-rw-r--r-- 1 lfs users 1780 Sep 20 11:16 /mnt/build_dir/tools/lib/crtn.o
I have no idea why they are not found by the linker. These are some
of the environment variables (when I am the ‘lfs’ user):
bash-4.3$ echo $LFS
/mnt/build_dir
bash-4.3$ echo $LFS_TGT
ppc-lfs-linux-gnu
I have this line in my /etc/fstab:
/dev/sda3 /mnt/build_dir ext4 defaults 0 2
The /tools directory:
bash-4.3$ ls -l /tools
lrwxrwxrwx 1 root root 20 Sep 18 15:27 /tools -> /mnt/build_dir/tools
It is maybe good to know that I never can run the build in one move.
I get sometimes a segmentation error when building gcc or glibc. It
is not reproducable: when I retry (with make -C $LFS/jhalfs) then it
succeeds or it ends with a segfault in another point of the build
process. It must have to do with the limited system resources (1.972
GB RAM and 3.660 swap space) or a latency problem. I try to avoid
this by disabling as much systemd services as possible and by
extending the stack space.
The error, I am struggling with, appears when I am so lucky to finish
the build of glibc.
