Hi all, Today, I was trying to compile the code with the 2013 version of Visual Studio, which was nicely provided by my school, and I wasn't able to because the most recent project is for 2012. And so I get an error like can't find gl.h or if I use the wrong toolset rror LNK2038: mismatch detected for '_MSC_VER': value '1700' doesn't match value '1800' Anyway, I wanted to know why you guys don't include a version.mk to get information about the release in the file ? That way you would solve lobby incompatibility between versions Regards stan I attached a mk version to see you what i'm talking about. Version.7z
