Dear Andreas,
thank you. I was able to build glibc back to version 2.22 on my machine
(x86_64 under Debian). In some cases I had to use CFLAGS="-Wno-error -O1"
to avoid some errors with -Werror. Also for <= 2.25 or before I had to use the
patch in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=869717.
But building 2.18-2.21 fails with:
/usr/bin/ld: /localdisk/zimmerma/glibc-2.20/build/csu/crt1.o: relocation R_X86_64_32S against symbol `__libc_csu_fini' can not be used when making a PIE object; recompile with -fPIE
I tried compiling with CFLAGS="-fPIE -O1" but I get the same error.
I also tried configure --disable-shared or configure --disable-static without
anu success.
Any clue?
Paul
