CGAL users discussion list

[BardoB <>]

Hi,

I've build the CGAL lib with macport. A "tool" for mac users to easily compile lib's.
The problem is you can't adjust the compile proces.

I will contact the port community about this problem.

Tanx for your advise!

Bardo

For some reason, the flag -frounding-math is not used. Try recompile CGAL:

  make clean
  make VERBOSE=1

and check the flags. If you compile a program, please also use make VERBOSE=1
to check the compilation flags.
