Blender Git Loki

Getting blender to compile for IRIX, in particular:

IK: needed to change abs() to TNT::abs() (thanks brecht!)

Freetype: FT_ENCODING_UNICODE typecast to FT_CharMap (thanks intrr!)

header_image: missing include for liballoc stuff

Ketsji: needed to declare m_hitObject as public in KX_MouseFocusSensor.h.
This is probably the wrong thing to do, but KX_MouseFocusSensor.cpp
compilation fails on line 279 otherwise.
