[Bug other/35377] New: stack-protector: multiple definition of `__stack_chk_fail_local'

[gzp at gmx dot net]

I was compiled and installed gcc-4.2.3 on Linux 2.4, glibc 2.3.6

main configure options was:

--enable-shared=libstdc++
--enable-static
--disable-debug
--enable-cpp
--enable-languages=c,c++
--enable-threads

After successfully compile and install got some problems when compiling apps
using the -fstack-protector option:

Linking C executable at-parser

libssp present only in static format, as libssp_nonshared.

------- Comment #1 from gzp at gmx dot net  2008-12-27 09:11 -------
ping, the problem still exist, due the combinations of the configure options
(static vs shared)

Changing in gcc/gcc.c

#define LINK_SSP_SPEC "%{fstack-protector|fstack-protector-all:-lssp_nonshared
-lssp}"

to


#define LINK_SSP_SPEC "%{fstack-protector|fstack-protector-all:-lssp}"

solved the problem.
