Re: pvrtex - PVR Texture Encoder

it 's ok.
suggest to add install target

Code: Select all

install: $(TARGET)
	install -s $(TARGET) $(DEST)

I don't know your environment
but guess
try

Code: Select all

find /opt/local/include  -name avconfig.h

better Physics Engine ?

This is using TapamN library and line example.

Is there a lightweight engine?
