Compiling a CGAL example program on Arch Linux with icpc

I want to compile an example program with CGAL 4.4 on Arch Linux with Intel Compiler.

But, on compiling this code, I got the following error:

$ icpc -o first_qp first_qp.cpp -lCGAL -I/usr/include/CGAL

The error message is here (pastebin)

What can I do?

# My box is up-to-date and the CGAL and boost library were already installed by pacman.

$ sudo pacman -Syu
$ sudo pacman -S cgal boost boost-libs

# I have already read an article about a similar question, but could not solve.

Solution

  • You should remove -I/usr/include/CGAL. It is not needed, and it confuses the compiler, which reads /usr/include/CGAL/gmp.h instead of /usr/include/gmp.h. Note that the recommended way to compile CGAL examples is with cmake (see the documentation), which handles all the flags for you.
