Hello to all, i need access the external header file from third party in Visual Studio.

I have settings the additional include directory but the files still cannot be found.

I sure that file located at the directory pj and the types.h is exist in the directory.

C:\Program Files\VOIP\pjproject-1.4\pjproject-1.4\pjsip\
C:\Program Files\VOIP\pjproject-1.4\pjproject-1.4\pjlib\include\pj\compat
C:\Program Files\VOIP\pjproject-1.4\pjproject-1.4\pjlib\include\pj
Any hints ?
C:\Program Files\VOIP\pjproject-1.4\pjproject-1.4\pjsip\include
C:\Program Files\VOIP\pjproject-1.4\pjproject-1.4\pjsip\include\pjsua-lib

The types.h locates at thisC:\Program Files\VOIP\pjproject-1.4\pjproject-1.4\pjlib\include\pj

I often encounter this kind of error when using third party source library.

Any hints

Please help.

Thanks.

You probably have to tell your compiler where pjsip\include is located. How to do that will depend on the compiler.

I follow your advise add this

C:\Program Files\VOIP\pjproject-1.4\pjproject-1.4\pjsip\include\

C:\Program Files\VOIP\pjproject-1.4\pjproject-1.4\pjsip\
to the Additional Include Directory but Visual Studio 2005

Thanks for your help.

The problem now become worse than before.
This library is VOIP PJLib.
