Re: Missing magic block

I've changed:

#ifdef PG_MODULE_MAGIC
PG_MODULE_MAGIC;
#endif

to:

#define PG_MODULE_MAGIC ;

and the .so does compile, but the database is still reporting the same
error when i try to CREATE FUNCTION:

ERROR: incompatible library "/home/mario/tests/psql_c_func/
test_func.so": missing magic block
HINT: Extension libraries are required to use the PG_MODULE_MAGIC
macro.

I searched for all fmgr.h files in the /usr and i got the output:

/usr/local/include/postgresql/server/storage/bufmgr.h
/usr/local/include/postgresql/server/fmgr.h
/usr/local/include/postgresql/server/fmgr.h.gch
/usr/local/pgsql/include/server/storage/bufmgr.h
/usr/local/pgsql/include/server/fmgr.h

So there obviously are more headers on the system, but i've tried to
compile the .so with the second and the last one. Both time the same
result.
