Hi Sylvain,

Hi Tom Dreyfus,
Installation Manual, chapter 2.4 Exact Arithmetic:Indeed.
"Having GMP version 4.1.4 or higher and MPFR version 2.2.1 or higher installed is *highly recommended*."
But I cannot install CGAL 3.4 without MPFR.
That is a documentation bug since GMP and MPFR are requirements.
You need to installed them both.
I thought MPFR was only needed when support for GMP was activated.
You are right, and I see that what I write is not the same... so let me try
again:
It is ether GMP+MPFR or none of them, which the documentation doesn't state.
If CMake detects GMP it will *require* MPFR, otherwise insallation will continue without GMP+MPFR support.
If you wish to bypass detection of GMP so that lacking MPFR doesn't prevent installation you should use: WITH_GMP=FALSE
Best
