I am making an UI with Qt for Googles OR-Tools and when trying to build logs go haywire with redefinitions...
The relevant part of my Qt project file looks like this
LIBS += or-tools_VisualStudio2017-64bit_v7.0.6546/ortools.lib
INCLUDEPATH += or-tools_VisualStudio2017-64bit_v7.0.6546/include
DEPENDPATH += or-tools_VisualStudio2017-64bit_v7.0.6546/include
The compiler complains about
C:\Program Files (x86)\Windows Kits\10\include\10.0.17763.0\shared\ws2def.h(103): warning C4005: "AF_IPX": Makro-Neudefinition

and so on ...
I am using OR-Tools in a class like this
#include "ortools/sat/cp_model.h"
using namespace operations_research;
using namespace operations_research::sat;
Already searched here on SO and on google and have tried
#define _WINSOCKAPI_
#define WIN32_LEAN_AND_MEAN
#include "ortools/sat/cp_model.h"
using namespace operations_research;
using namespace operations_research::sat;
But that doenst help...
What is very confusing is that when i used that same include in another console only Qt test project it worked...
With Notepad++'s "search in files" i found out the library headers that depend on windows.h are
spinlock_win32.inc
stacktrace_win32-inl.inc
symbolize_win32.inc
waiter.h
CoinTime.hpp
zconf.h
And those that include winsock2.h are
time.h
time_util.h
However, I'd rather not chage anything in them and like to have it work out-of-the-box like it did with my console only test project...
Im am using Qt 5.12.0 MSVC2017 64 Bit and am on Win10
Adding a DEFINES += _WINSOCKAPI_ in the Qt project config file (*.pro) has solved it.
