Well, on 32-bit system GLInt is alias for int, int32 To check its size you can do something like following: (NBFFICallout new requestor: <put a class which has access to GLInt>; resolveType: 'GLInt') typeSize Try NBExternalType sizeOf: 'GLInt' > > -- > View this message in context: > http://forum.world.st/Understanding-NBOpenGL-tp4686514p4695790.html > Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com. > -- Best regards, Igor Stasenko.
