Question

Here is the command and the error.

gcc --shared  \
        -m64 \
        -shared-libgcc \
        -Wl,--whole-archive ./release64/*.a
/usr/lib64/libc_nonshared.a(elf-init.oS): In function `__libc_csu_init':
(.text+0x1d): undefined reference to `__init_array_end'
/usr/bin/ld: /usr/lib64/libc_nonshared.a(elf-init.oS): relocation R_X86_64_PC32 against undefined hidden symbol `__init_array_end' can not be used when making a shared object
/usr/bin/ld: final link failed: Bad value
collect2: ld returned 1 exit status
make: *** [build] Error 1

What does this mean?

Answer 1

By leaving a “hanging” --whole-archive option, you trick GCC into trying to link code compiled without -fPIC (from libc_nonshared.a) into a shared library. Don’t do that. Do this instead:

gcc -shared ... -Wl,--whole-archive release64/*.a -Wl,--no-whole-archive
