CGAL users discussion list

Thank you for your reply!
I didn't create an environment variable pointing to CGAL3.5's dir, so the
default was /usr/local, I guess. Now, when configuring, I set
CMAKE_INSTALL_PREFIX to CGAL 3.7 and with cmake
-DCGAL_DIR=$CMAKE_INSTALLED_PREFIX/lib/CGAL it works.

Conversely if I compile the examples I have the following error for
"algebraic_curves":

Any suggestions?
Thank you in advance!






Cecilia,

Did you created a environment variable pointing to CGAL3.5's dir? If so,
I think you need to update it with the CGAL3.7's dir.

What's more, make sure the include dir of 3.5 has been excluded and
3.7's has been added to the project in case you are using Visual Studio.

Subject: [cgal-discuss] Installing CGAL 3.7

Hi,
I tried to install CGAL 3.7 keeping the version CGAL 3.5 also on my
laptop. So I built the CGAL 3.7 libraries in a new separate directory to
avoid conflicts between the libraries of the version 3.5. Nevertheless I
noticed that in the depend.internal file the include points to the header
files of the old version. Also changing the command include_directories in
the CMakeList file the problem persists. How can I avoid the conflict?
Thank you in advance!
