Hi Chris,
The problem here is actually the ordering of your command line. When you
compile and link in a single command line with g++, you must list the
libraries after the source code. Otherwise, the libraries do not get
properly linked in. Thus,
g++ blitztest.cpp -lblitz -lm
Also, you may need to add the appropriate -I and -L flags to indicate the
location of the blitz header files and library.
Regards, Julian C.
