Problem linking with pthreadVC2.lib (newbie)

Problem linking with pthreadVC2.lib (newbie)

[Rajiv Kumar]

I have built the static pthread library: nmake VC-static
I have a test program(test.c) with only two lines of code  in main():
	pthread_mutex_t mutex = NULL;
	pthread_mutex_lock(&mutex);
I include pthread.h in the test program and link with pthreadVC2.lib
I get the following link error :
error LNK2019: unresolved external symbol __imp__pthread_mutex_lock
referenced in function _main
fatal error LNK1120: 1 unresolved externals
Im using MSVC 7.1 on win2k.
Please advise to resolve this.

You need to define PTW32_STATIC_LIB for your application build (I think
this is in the (rather too long) README file). It's used by pthread.h to
switch off the import/export dll declspec stuff. The reason for the
explicit define is that some people want to statically link pthreads-
win32 into their own dll build, and so using the predefined _DLL
conflicts.
