When I try to run the make file under the examples directory, I received issues in regards to CLPSimplex.cpp not in the path so I modified the makefile to include the source files.  Now, I'm getting the error below.  Any ideas on how to resolve this issue?  I searched the web and the only thing I can come up with is that I may be using the wrong compiler.

The includes seem wrong. For building the example, the compiler should 
not include files from C:/clp_build/clp/src/ but from 
/cygdrive/c/clp_build/include/coin.
The latter is also stated first in the include paths.
It sounds like you did wrong modifications to the Makefile.

Did "make install" install all headers without problems in 
C:/clp_build/include/coin ? I.e., is ClpSimplex.hpp there?
