10.6 Build for MS Visual C++
We do not support compilation directly under MS Visual Studio, i.e. we do not provide workspace files (.dsw) or project files (.dsp).
However the executables created are debuggable using the debugger of MS Visual Studio. You may have to help the debugger finding the path to source files the first time you debug a given executable.
A package and setup which is not officially supported, and including the required configuration for creating a project under Visual Studio, can be downloaded here.
