glibc error while building linux from scratch

Question

The following error came up when i did 'make' of glibc-2.14.1 for LFS 7.1. I am using ubuntu as the host OS.

Can anyone tell me what to do?

Answer 1

For glibc 2.15, I had to do like ks1322:

$ ../glibc2.15/configure CFLAGS="-O2 -U_FORTIFY_SOURCE -fno-stack-protector" $ make

The -O2 is required to recover the default optimisation, required to avoid a number of failures.

The -U_FORTIFY_SOURCE is required to avoid failure of gcc ../sysdeps/unix/sysv/linux/syslog.c ( In function '__vsyslog_chk': [...] inlining failed in call to 'syslog' )

The -fno-stack-protector is required to avoid failure of gcc [...] elf/dl-allobjs.os libc_pic.a ( (init-first.os):(.data+0x0): multiple definition of '__libc_multiple_libcs' ).

With these CFLAGS , I get just a warning ( errlist.c count 133 inflated to GLIBC_2.12 count 134 (old errno.h?) ).

PS It is also very important to not use the gold linker ( ld.gold , from the binutils-gold package), because libc 's config will reject it. This is easily done by changing the /usr/bin/ld symbolic link from ld.gold to ld.bfd .

Answer 2

After make failed, the following worked for me:

make clean
make -j2 CFLAGS="-U_FORTIFY_SOURCE -O2 -fno-stack-protector"

See details in this blog http://www.yonch.com/tech/78-compiling-glibc .

Answer 3

glibc build issues, inlining failed

Need to add -U_FORTIFY_SOURCE to the gcc invocation.

Answer 4

@avinash - try the following ...

1) re-run configure ... CFLAGS="-O2 -U_FORTIFY_SOURCE" ./configure
2) re-run make ... CFLAGS="-O2 -U_FORTIFY_SOURCE" make
