CGAL users discussion list

[Amir Vaxman <>]

Hello,

I have recently converted my religion from Windows to Linux Mint, and
am trying to use CGAL copiled by g++ 4.6. I have configured cmake
using:

amir@amir-office ~/workspace/CGAL-4.0.2 $ cmake -fp-model strict .

the building went ok, but I get the following assertion when running:

CGAL_assertion_msg(-CGAL_IA_MUL(-1.1, 10.1) != CGAL_IA_MUL(1.1, 10.1),
                         "Wrong rounding: did you forget the
-frounding-math  option if you use GCC (or  -fp-model strict  for
Intel)?");

It seems as if this option was added, so what is the problem?

Thanks,
Amir.
