I downloaded the tar ball for Open Video editor and get the following errror
rBezier.o -MD -MP -MF .deps/CurveEditorBezier.Tpo -c -o CurveEditorBezier.o CurveEditorBezier.cxx
In file included from CurveEditorBezier.cxx:8:0:
../../src/VideoViewGL.H:43:19: error: ‘int64_t’ has not been declared
../../src/VideoViewGL.H:44:14: error: ‘int64_t’ has not been declared
../../src/VideoViewGL.H:52:3: error: ‘int64_t’ does not name a type
make[3]: *** [CurveEditorBezier.o] Error 1
All the files required according to the install instruction have been added plus the development versions.

Still, I suspect that there is a file missing.

Has anyone a clue what is missing?

Thanks and cheers from OZ
