Sounds like you might need a -L option gcc -o testclapack testclapack.c -L<dir to library> lapack.a -cblaswr -lblas.a tmglib.a -latlas -lg2c
You can stack multiple -L options, one per directory (no space after the -L), the same as the -I options. also, the -l<libname> is a special convention that ONLY works when the libraries have a physical name of lib<libname>.<a|so>. For instance -lmath means that somewhere in a known location there is a file called libmath.a or libmath.so. So, since the clapack libraries don't follow that convention, you can't use the -l shortcut. You have to give it the full name.
