Hi, This applies to GLUT_EXCLUSIVE_FPUMODE mode inside packages/opengl/src/glut.pp source code. Reading history, I see it was caused by this bug and patch: http://bugs.freepascal.org/view.php?id=7570 . However, it's not needed anymore, IMHO. It seems submitter of #7570 hacked glut unit, suspecting the troubles inside GLUT, while in fact it is OpenGL library causing floating point trouble.
Moreover, since FPC 2.2.0, we have a correct fix inside the gl.pp unit itself (see #5914 and #7570). Inside gl.pp, we do SetExceptionMask to hide fpu errors that may be raised by some OpenGL implementations on all x86. This, in my view, makes the GLUT_EXCLUSIVE_FPUMODE not needed. The GLUT_EXCLUSIVE_FPUMODE duplicates the work (adds the same ExceptionMask flags) that is already done, in much simpler way, by gl.pp initialization. Comments? P.S. On an unrelated note, I'm preparing a patch to add freeglut extensions to glut unit. It's actually ready, but now I'm wondering if it's worth the trouble to deal with complications caused by GLUT_EXCLUSIVE_FPUMODE, when instead we could just remove the GLUT_EXCLUSIVE_FPUMODE hack :) Michalis _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
