Dear Mr. Randi J. Rost, et al.:
I have a copy of your book entitled, OpenGL Shading Language, Second Edition, T 385 R665 2006 MAIN, UT Austin, and learned that you have also worked with Motif. I have had a problem getting my "long double" version of XEphem 3.7.2 to build under Red Hat Linux Fedora 7, x86_64 on an AMD Athlon 64 X2 Dual-Core Processor 5600+ based PC. It builds OK under Red Hat Linux Fedora Core 6 on a Celeron based 32-bit computer. I could then bring the 32-bit application executable to the 64-bit PC, and it worked fine also. However, I could not get it to build (using make) on the 64-bit PC, even when I had specified ~ gcc -m32 . . ., using the latest GNU GCC Compiler Collection (i.e., gcc-4.1.2-33.x86_64.rpm, et caetera, installed). Also, when I tried a simple C program - NO Motif at all involved - I got compile error messages related to ~ stdlib.h, ~ 32 bit stub missing, I seem to recall, for, I'm not at home now. I obviously would like to be able to also build on my 64-bit PC, as well as develop and run in that environment entirely. Any assistance would be most gratefully appreciated.
