Hi Carsten,
as a starting point, I had just copied the source of testPassiveQT4.cpp into my
source tree, to call it from my window manager. So the ordering of the files
was exactly as in the testPassiveQT4.cpp.
the problem is in the OSGConfig.h
i had to comment the lines, that you described:
//# include <AvailabilityMacros.h>
//# if !defined(MAC_OS_X_VERSION_10_5) || (MAC_OS_X_VERSION_MAX_ALLOWED <
MAC_OS_X_VERSION_10_5)
//# define OSG_GLENUM_NEQ_UINT32
//# endif
now it works. here are the lines of my AvailabilityMacros.h, that might matter:
* Set up standard Mac OS X versions
*/
#define MAC_OS_X_VERSION_10_0 1000
#define MAC_OS_X_VERSION_10_1 1010
#define MAC_OS_X_VERSION_10_2 1020
#define MAC_OS_X_VERSION_10_3 1030
#define MAC_OS_X_VERSION_10_4 1040
#define MAC_OS_X_VERSION_10_5 1050
#define MAC_OS_X_VERSION_10_6 1060
[…]
/*
* if max OS not specified, assume largerof(10.6, min)
*/
#ifndef MAC_OS_X_VERSION_MAX_ALLOWED
#if MAC_OS_X_VERSION_MIN_REQUIRED > MAC_OS_X_VERSION_10_6
#define MAC_OS_X_VERSION_MAX_ALLOWED MAC_OS_X_VERSION_MIN_REQUIRED
#else
#define MAC_OS_X_VERSION_MAX_ALLOWED MAC_OS_X_VERSION_10_6
#endif
#endif
i am running mac os x 10.6.7 with macports 1.9.2.
there was another problem. make install did not copy the library files to the
destination directory, and OpenSG_LIBRARIES was empty. i solved that now, by
copying them myself, and setting the variable by hand.
regards,
keyan
