I've managed to to use mpfr-mpir-gmp in CodeBlocks but I want to in eclipse C++:

When I compile the code it compiles and build but if I run the project it says: "error while loading shared libraries: libmpfr.so.6: cannot open shared object file: No such file or directory".

So can anyone show me how to configure eclipse to use gmp-mpifr-mpir correctly?

  • If I compile from a terminal: 

    g++ -lmpir -lmpfr -lgmp myEclpiseMPFRMPIRproj.cpp

then :

./a.out

It works fine and doesn't complain about the same problem. So I think I don't know how to pass those flags -lgmp, -lmpir -lmpfr.

Thank you.

I've figured it out after thousands of attempts without giving up. I am happy to share it for someone who may face the same problem:

When I've built and installed "gmp, mpfr, mpir" I've used sudo make install so the library is in /usr/local thus when I create a project with Eclipse-CDT everything is there only I add the flag to the linker:

 Project->properties->C/C++ Build->Settings->GCC C++ Linker->Command and add:

g++ -lgmp -lmpir -lmpfr
  • Apply and Close. Now build and run. It works fine!

N.B: The problems I've faced already because I've add the library paths and files and include paths so I've removed them all.
