1) fix evil use of internal scons interfaces that breaks latest scons version.
2) a hack to turn on new CCGSUBSURF stuff by adding -DUSE_CCGSUBSURFLIB
to extra_flags. This is currently the default for all platforms except
win32 (due solely to my ignorance of win32 compiler flags).
To enable it you will need to download OpenEXR and install it.
For the Makefiles you will need to set WITH_OPENEXR=true
and set NAN_OPENEXR to point to where OpenEXR is installed.
For scons you'll need to remove config.opts to get the new options
so you can enable OpenEXR, I was not able to get blender to link
with scons so the scons stuff may need to be tweaked a little but
I think it should work.
For other platform managers The OpenEXR stuff is similar to QUICKTIME
you need to define WITH_OPENEXR and setup the library stuff and
as you'll notice in this commit there are two extra files.
