Error using ff-c++

FreeFEM installation
1

While trying to compile lapack with ff-c++ lapack.cpp -llapack I get the error erreur PB include freefem++ directory
My freefem files compile well until I am not loading lapack. Probably the mistake is stupid but I can’t find a solution.

Someone know what is wrong?

Dear user ,

You give not information on the computer, system, version of FreeFEM,
So it is hard to say something.
