I have been using lp_solve with mingw with no problems that I recall.

One quick comment:  lp_solve is c, not c++, so (in c++ code) you want
to include the lp_solve header as follows:

   extern "C" {
   #include "lp_lib.h"
   }

"CXX object" and "lp_solve5test.cpp.obj" suggest that you are using
c++, so perhaps c vs. c++ is the issue, and using "extern "C"" will
clean things up

If that doesn't work, come back with more questions.  As I said, I have
lp_solve working smoothly (with a c++ application) using mingw, so we
ought to be able to get things sorted out for you.

Good luck.
