I hope someone may have some quick advice for me on this one. I have routinely been using the G++ compiler in my programming, and have recently rewritten some of my code in normal C instead of C++ for reasons of efficiency and portability. The rewrite was not difficult, and I finally got one package of about 2000 lines of code to compile without errors or warnings. However - the linking step failed when none of the math functions required in the program could be located by the GCC linker. The same functions in the C++ version compiled by G++ were found with no problem. The functions were: sqrt, log, log10, trunc, int, double, float, etc. The header file math.h was present (without it, compile errors result) but evidently the C math library could not be found. I tried reinstalling my gcc.tgz and glibc.tgz packages to no avail. I am now heading for the howto's and docs to see what I can learn. Any help from you programmers out there would be greatly appreciated. My system: Slackware 8.0, kernel 2.4.18, GCC 2.95.3 Thanks - Chuck -- The Moon is Waning Crescent (4% of Full) So visit me at http://www.valstar.net/~hallenbeck
