René, Thanks very much for replying so quickly. I've just tried: dllwrap -o uuid.dll --def uuid.def uuid.o /usr/lib/postgresql/pgxs/src/../../src/utils/dllinit.o -L/usr/lib -lpostgres -Wl,-Bstatic -luuid -Wl,-Bdynamic dllwrap -o uuid.dll --def uuid.def uuid.o /usr/lib/postgresql/pgxs/src/../../src/utils/dllinit.o -L/usr/lib -lpostgres -L/usr/lib/w32api -Wl,-Bstatic -luuid -Wl,-Bdynamic and dllwrap -o uuid.dll --def uuid.def uuid.o /usr/lib/postgresql/pgxs/src/../../src/utils/dllinit.o -L/usr/lib -lpostgres -L/usr/lib/w32api -Wl,-Bstatic,-luuid,-Bdynamic All three give the same errors: uuid.o:uuid.c:(.text+0xe): undefined reference to `_uuid_compare' uuid.o:uuid.c:(.text+0x55): undefined reference to `_uuid_generate_random' uuid.o:uuid.c:(.text+0x98): undefined reference to `_uuid_parse' uuid.o:uuid.c:(.text+0x174): undefined reference to `_uuid_unparse_lower' uuid.o:uuid.c:(.text+0x2fd): undefined reference to `_uuid_unparse_lower' collect2: ld returned 1 exit status dllwrap: gcc exited with status 1 Probably should have mentioned: latest Cygwin DLL, Cygwin (not native Windows) PostgreSQL 8.1.4, latest w32api.
