hm, I'm still stuck: can't compile extension with mingw compiler. I use Dev-CPP IDE (4.9.9.2) with MingW 3.7. Has it been tested to compile extensions under XP with PostgresQL 8.1.2 ? Al I get are compiler errors: gcc.exe -c fd.c -o fd.o -I"C:/Dev-Cpp/include" -I"D:/.Work/postgresql/postgresql-8.1.2/src/include" -I"D:/.Work/postgresql/postgresql-8.1.2/src/include/port/win32" -I"D:/.Work/postgresql/postgresql-8.1.2/src/include" -I"D:/.Work/postgresql/postgresql-8.1.2/src/include/port/win32" -DBUILDING_DLL=1 -DWIN32 -DWIN32_CLIENT_ONLY=0 D:/.Work/postgresql/postgresql-8.1.2/src/include/port/win32.h:181: error: redefinition of typedef 'pid_t' C:/Dev-Cpp/include/sys/types.h:75: error: previous declaration of 'pid_t' was here In file included from D:/.Work/postgresql/postgresql-8.1.2/src/include/postgres.h:48, from fd.c:8: D:/.Work/postgresql/postgresql-8.1.2/src/include/c.h:328: error: redefinition of typedef 'sig_atomic_t' C:/Dev-Cpp/include/signal.h:46: error: previous declaration of 'sig_atomic_t' was here In file included from D:/.Work/postgresql/postgresql-8.1.2/src/include/access/tupdesc.h:18, from D:/.Work/postgresql/postgresql-8.1.2/src/include/utils/rel.h:17, from D:/.Work/postgresql/postgresql-8.1.2/src/include/storage/bufmgr.h:21, from D:/.Work/postgresql/postgresql-8.1.2/src/include/storage/bufpage.h:18, from D:/.Work/postgresql/postgresql-8.1.2/src/include/access/htup.h:17, from D:/.Work/postgresql/postgresql-8.1.2/src/include/utils/tqual.h:18, from D:/.Work/postgresql/postgresql-8.1.2/src/include/access/relscan.h:18, from D:/.Work/postgresql/postgresql-8.1.2/src/include/nodes/execnodes.h:17, from D:/.Work/postgresql/postgresql-8.1.2/src/include/executor/execdesc.h:19, from D:/.Work/postgresql/postgresql-8.1.2/src/include/executor/executor.h:17, from fd.c:10 ..... ..... ..... >>I was wondering if I can use VC compiler to compile UDF DLL ? >>If yes then I am wondering why I am getting linking errors: >> >>Compiling... >>fd.c >>Linking... >> Creating library Debug/fd.lib and object Debug/fd.exp >>fd.obj : error LNK2001: unresolved external symbol >>_CurrentMemoryContext Debug/fd.dll : fatal error LNK1120: 1 >>unresolved externals >> >> >>It seems that linker is not able to find symbol CurrentMemoryContext. >>This variable is declared in palloc.h, but I can't find the >>implementation of this variable in libpostgres.a ? >> >> > >No, you need to use mingw to compile extensions. > >//Magnus > >---------------------------(end of broadcast)--------------------------- >TIP 9: In versions below 8.0, the planner will ignore your desire to > choose an index scan if your joining column's datatypes do not > match > >
