PG_MODULE_MAGIC lost if strip the object file

Hi list,
I create a dynamic library with the PG_MODULE_MAGIC under Linux.
No problem in normal situation, but if I strip the .o file,
that information seems to get lost and I get:
ERROR: incompatible library "...so": missing magic block
TIP: Extension libraries are required to use the PG_MODULE_MAGIC macro.

I want to strip my code to make it harder to use gdb on it.
Any suggestion how I can get it working "with" stripping the .o file?

How about not compiling with -g?

Don't strip global symbols.
