Hi, I'm trying to implement the add_one sample in the PG docs using VC++ (for purposes of debugging). After some pain (had to add the dllexport declspec below), I am able to get the CREATE FUNCTION command to recognize the library and function. However, the function blows up. I am able to attach the postgres.exe process and debug this dll (I set a breakpoint on the int x = 1 line). I do get that far, but then blow up trying to retrieve my argument on the following line. Digging into this, I find that the fcinfo struct being passed to me as an address of 0x000002 - that looks a little non-sensical to me.
I am wondering if I've got the necessary project settings in Visual Studio. How do we create a VC++ dll that is compatible with the gcc PG build? Does anyone have a clue as to what these might be? I have been doing a lot of digging and haven't seen anything directly addressing this issue. Many thanks....Eric __declspec(dllexport) Datum add_one(PG_FUNCTION_ARGS) { int x = 1; int32 arg = PG_GETARG_INT32(0); PG_RETURN_INT32(arg + 1); } ---------------------------(end of broadcast)--------------------------- TIP 7: You can help support the PostgreSQL project by donating at http://www.postgresql.org/about/donate
