How to compile OSG library using MinGW on Windows?

Question

C++ / C#

I'm trying to compile a fork of the OSG library with a built-in osgjs plugin to convert 3d models to . osgjs format.
Pre-installed MinGW .
I build the project using CMake-gui.
After the build, I go to the folder with the build, launch the Git Bash console and type the command $ mingw32-make.
During compilation, the following error is thrown:

In file included from D:/osg-master/include/osg/BufferObject:18:0,
                 from D:/osg-master/include/osg/Image:17,
                 from D:/osg-master/include/osg/AudioStream:17,
                 from D:\osg-master\src\osg\AudioStream.cpp:14:

PS When you try to compile the original library , everything goes well.
PPS Windows 8.1, CMake 3.1.0-rc, gcc 4.8.1
Tell me what to do in this situation?

Answer 1

Make sure you are using the correct cmake generator . You need MSYS Makefiles. I do not know how in the GUI, but in the console
cmake -G "MSYS Makefiles"

Answer 2

Surface googling showed. That __int64 is this type of 64-bit int in the Microsoft compiler and in gcc (and therefore in mingw) it is not. Most likely you have configured for VS
