Can't see the huge ass image link
We are in the same boat, i'm also trying to compile the source but in VS2015, after some internet search was able to make everything compile minus the penumbra.exe, get two linking errors:
Error LNK2001 unresolved external symbol __imp___vsnprintf Penumbra
H:\UnamedGame\PenumbraOverture\angelscript.lib(as_string.obj) 1
Error LNK2001 unresolved external symbol __imp___vsnprintf Penumbra H:\UnamedGame\PenumbraOverture\angelscript.lib(as_string_util.obj) 1
This seems to be caused by the very old angelscript.lib and unfortunatly using a modern lib causes many compilation errors, so right now it seems i can't compile the engine.
