i've written a program in C that connects with a MySQL Database.
When it compile : gcc mysql_ins_server.c -o mysql_ins_server -I
/usr/local/mysql/include/ -L /usr/local/mysql/lib/ -lmysqlclient -lz

i take the follwoing errors:
/usr/lib/libc_nonshared.a(elf-init.oS)(.gnu.linkonce.t.__i686.get_pc_thunk.bx+0x 0):
In function `__i686.get_pc_thunk.bx':

because im' new to Linux i haven''t find out anything yet. Any help
appreciated.

Make sure you have a recent version of GCC and binutils. I just ran
into the same problem with python 2.4.3. It had nothing to do with the
code base. The linker was broken and an update of my binutils fixed the
issue.
Kind regards,
