[HACKERS] Help! DLL make faild under windows mingw.
I am doing a DLL project, it is in the backend/utils/mb. But it can not be maked under windows mingw. I require everyone to help me. Thank your very much. The error infomations are as follows.

Hi! What exactly are you trying to build? If you have own-written Makefile for this - post it here. Does your code contain #define BUILDING_DLL before inclusion of PostgreSQL headers?

Re: [HACKERS] Help! DLL make faild under windows mingw.
You are right. Thanks. I found macro BUILDING_DLL in the file src/Makefile.port. I move the DLL source code from the backend path. It can be successfully built. The file Makefile.port contains ifneq (,$(findstring backend,$(subdir))) ifeq (,$(findstring conversion_procs,$(subdir))) override CPPFLAGS+= -DBUILDING_DLL endif endif - Original Message - From: Andrei Kovalevski [EMAIL PROTECTED] To: pgsql-hackers@postgresql.org Sent: Wednesday, May 30, 2007 1:35 AM Subject: Re: [HACKERS] Help!
