Hello, by running Flightgear I noticed that although Simgear was able to compile with the following changes a severe run-time error occured. The problem is the definition of isinf and isnan in the follwoing files simgear/scene/cloudfield.cxx and simgear/scene/cloud.cxx #if defined (__APPLE__) // any C++ header file undefines isinf and isnan // so this should be included before <iostream> inline int (isinf)(double r) { return isinf(r); } inline int (isnan)(double r) { return isnan(r); } #endif The code behaves like an endless loop. The solution is: 1) delete the definition of isinf because it is never used, 2) define isnan different. After the change the definition in both files should be: #if defined (__APPLE__) // any C++ header file undefines isinf and isnan // so this should be included before <iostream> inline int (isnan)(double r) { return !(r <= 0 || r >= 0); } #endif The other changes are: simgear/scene/model/shadowvolume.cxx line 874: int to GLint simgear/scene/sky/bbcache.cxx line 112: int to GLint simgear/screen/shader.cpp line 221: int to GLint line 294: int to GLint line 308: int to GLint line 387: int to GLint With the above changes I was able to build the current Simgear and Flightgear cvs sources on Mac OS X 10.4.2. Although the intro-screen of Flightgear contains only strange lines of different color after initialization Flightgear seems to run normal now on my machine.
