I am trying to use the g++ compiler. I have obtained a test file from the 1.36 release. However, I can't get it to compile. I beleive that I have to include some library or change my search path somehow, but I can't figure out how. I have tried the -lm switch and it eliminates sqrt from the list of undefined symbols. What library or other file do I need ? I append a script below. % g++ libg++/tests/tRandom.cc tRandom.o: Undefined symbol _sqrt referenced from text segment tRandom.o: Undefined symbol _sqrt referenced from text segment tRandom.o: Undefined symbol _sqrt referenced from text segment tRandom.o: Undefined symbol _sqrt referenced from text segment tRandom.o: Undefined symbol _log referenced from text segment tRandom.o: Undefined symbol _sqrt referenced from text segment tRandom.o: Undefined symbol _log referenced from text segment ../g++-include/RNG.h:82: Undefined symbol _log referenced from text segment ../g++-include/RNG.h:82: Undefined symbol _log referenced from text segment Random.cc:90: Undefined symbol _log referenced from text segment Random.cc:90: Undefined symbol _sqrt referenced from text segment Random.cc:106: Undefined symbol _exp referenced from text segment ../g++-include/RNG.h:82: Undefined symbol _floor referenced from text segment ../g++-include/RNG.h:82: Undefined symbol _log referenced from text segment ../g++-include/RNG.h:82: Undefined symbol _pow referenced from text segment Random.cc:154: Undefined symbol _log referenced from text segment Random.cc:166: Undefined symbol _pow referenced from text segment Sample.cc:62: Undefined symbol _tan referenced from text segment Sample.cc:64: Undefined symbol _sqrt referenced from text segment Sample.cc:68: Undefined symbol _log referenced from text segment Sample.cc:68: Undefined symbol _sqrt referenced from text segment Sample.cc:74: Undefined symbol _exp referenced from text segment Sample.cc:125: Undefined symbol _sqrt referenced from text segment Sample.cc:0: More undefined symbol _sqrt refs follow % Ingemar Hulthage Scientist, PhD Carnegie Mellon Research Institute Phone: (412) 268-6376 Home: 306 S.
