You print the version of gcc. Did you install CGAL?

 

 I test CGAL with ubuntu and it did not install on it even with the presence of GCC. the error was "setup did not find any compiler on system". I think there it is a bug with setup finding the compiler but I did not have enough time to create a bug report.

 

I am also wondering why CGAL can not be install in ubuntu.

Subject: [cgal-discuss] Is this a bug in the library?

Hello everyone,

I want to use the CGAL library but there is something really weird. I
just #include the header file Cartesian.h (nothing else), and then my
compiler becomes crazy! I'm using Ubuntu Linux with g++

~$ g++ --version
g++ (GCC) 4.1.2 (Ubuntu 4.1.2-0ubuntu4)
Copyright (C) 2006 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is

Is this a bug in the library? How come I cannot even include a header
file? I took a look at line 37 of /usr/include/CGAL/Straight_2.h and
there is no '(' token. Does anyone know why is this and if it has a
fix???

Thank you all,

Alejandro M. Aragón
