SVL (simple vector library) http://www.cs.cmu.edu/~ajw/doc/svl.html
and FLTK ... has linking problem. Please help!!
I used the "shape.cxx" in test directory.
include <svl/svl.h>;
in main():
test the matrix functions: initiate a matrix and compute its trace.
Mat2 is OK, Mat3 and Mat4 seems to have problems.
Any pointer greatly appreciated.
I use FLTK 1.1.10rc, SVL-1.5, VC6.0
