Yes, most of the time it is, mac is very sensitive to data alignment, all gl functions expect stack to be aligned to 16 bytes before calls.
Quote:Error before swap has following meaning: in ZZoglCRTC we check glstate before swap buffwers (we draw picture on backbuffer and swap it each frame to made a picture clear). If there error before, than CRTC part (when buffer is complete) have bug. Maybe it is interlacing issue. As you know, I change shaders file, and redone interlacing part. So my shaders could have issues on mac.
Debugging it some more it actually breaks in AlphaTest() leading to error in gleLLVMLoadDataFromAryFloatInFloat
Quote:p.S. Xlib: extension "XFree86-VidModeExtension" missing on display "/tmp/launch-nFuQ2X/:0" -- is this expected?
yes, it's expected
ah, ok, fixed it. Copied from my previous notes the wrong way, on mac all the EXT functions don't work so SET_STREAM should look
#define SET_STREAM() { \
glColorPointer(4, GL_UNSIGNED_BYTE, sizeof(VertexGPU), (void*)8); \
glSecondaryColorPointer(3, GL_UNSIGNED_BYTE, sizeof(VertexGPU), (void*)12); \
glTexCoordPointer(3, GL_FLOAT, sizeof(VertexGPU), (void*)16); \
glVertexPointer(4, GL_SHORT, sizeof(VertexGPU), (void*)0); \
}
like this, and originally it was
#define SET_STREAM() { \
glColorPointer(4, GL_UNSIGNED_BYTE, sizeof(VertexGPU), (void*)8); \
glSecondaryColorPointerEXT(4, GL_UNSIGNED_BYTE, sizeof(VertexGPU), (void*)12); \
glTexCoordPointer(3, GL_FLOAT, sizeof(VertexGPU), (void*)16); \
glVertexPointer(4, GL_SHORT, sizeof(VertexGPU), (void*)0); \
}
So forgot to change 4 to 3
