Hello Bill,
sorry for the delay. Here is the output of top at different times during
the process of compiling and linking the code. BTW the libs ld has to link
together are:
- -lGL -lGLU -lboost_filesystem -lboost_date_time -lode -lxerces-c
- -lCgGL -lCg -lrt -lvorbisfile -lvorbis -lm -logg -lalut -lopenal
- -lmagic -lIL -lpython2.4 -lruby -lpthread
