linker errors when compiling and linking with a new glibc

[Daniel De La Zerda]

I do have do have /lib/libgcc_s.so.1 but how do I point to it from my "glibc-2.4-build" tree (I'm making some modifications to glibc). I was able to compile my test for the new feature but when trying to run it I get that error. Also, doing a "make tests" inside my "glibc-2.4-build" tree fails on "tst-mutex8.c" for the same reason.

See nptl/sysdeps/pthread/uwnind-resume.c and unwind-forcedunwind.c.

The pthread_cancel_init implementation in glibc dlopen()'s the
compiler helper routine shared library (libgcc_s.so.1) in order to access
the stack unwinding functions.

Did you install the compiler helper routine shared library on your system?

It is normally located in /lib/libgcc_s.so.1, or similar.
