Getting errors when include <WinSock2> on Visual Studio 2015

Question

I'm trying to compile my project where I've just added the use of 'WinSock2.h'.I'm getting these errors:

    c:\program files (x86)\windows kits\8.1\include\um\wingdi.h(2898): error C2208: '_POINTL' : no members defined using this type
    c:\program files (x86)\windows kits\8.1\include\um\winuser.h(14564): error C2208: 'unsigned int'  : no members defined using this type
    more

I have searched solutions to my issue, I've added _WINSOCKAPI_ on preprocesseur rules and only the two errors up there are remaining. I have also tried adding WIN32_LEAN_AND_MEAN and still the same.

My project uses ALLEGRO library and "windows.h" file.

Have you a explanation of my problem?

Answer 1

The compilator errors point to files winuser, wingdi, propild, oaidl. These files has been added from the use of network library, on windows.h I guess. The offending lines deal of following field definitions: unit, date, position. All these name was already used on preprocessor definition on my project, leading to a conflict of definition.
