Compiler issues with Eclipse CDT

​ou can't build GMP with Eclipse. You have to build GMP separately using
msys/cygwin​; this will produce a library (either static or dynamic
according to your build option) that you should then link into your program
using your interface of choice (here, Eclipse CDT).

Your error indicate that the GMP source directory is in your build path,
which is incorrect. Once you've built the GMP library, you should not have
any reference to the GMP source, except for the "include" directory.
