I wrote a little make file which takes care of this part (except restarting the session): INCLUDEDIRS += -I$(shell pg_config --includedir-server) LIBDIR = -L$(shell pg_config --libdir) LIBINSTALL = $(shell pg_config --pkglibdir) integrated_c.so: integrated_c.c Makefile gcc -fpic -o integrated_c.o -c integrated_c.c $(INCLUDEDIRS) gcc -shared -o integrated_c.so integrated_c.o $(LIBDIR) -lmpfr -lgmp cp integrated_c.so $(LIBINSTALL) -----Ursprüngliche Nachricht----- Von: Tom Lane [mailto:tgl@xxxxxxxxxxxxx] Gesendet: Montag, 18.
