There's quite  a number of linker things you need to really make CGAL and GMP work. I'm on 64 bit. But this is what my project looks like:

VC++ Directories:

boost/lib64-msvc-12.0

gmp/include

C/C++ Additional Includes:

CGAL/include

boost root directory

CGAL/auxiliary/gmp/include

Linker Additional Library Directories:

CGAL/auxiliary/gmp/lib

boost root/lib64-msvc-12.0

CGAL/build/lib

Some of these may not be necessary (or correct) but my projects compile correctly with these settings.

Hello,

I'm trying to install CGAL on my computer but I encounter some difficulties
(during the building in DEBUG and RELEASE of ALL_BUILD I got linked errors
LNK2019 for CGAL_CORE --> linked problem with the library GMP). So I'm
wondering if I have installed the correct version of my libraries :

- my computer : Windows 7 - 64bit

- Visual Studio, I used : Tools -> Visual Studio Command Prompt -> enter
"cl.exe" to know what I have. I have :
C:\program files <x86>\microsoft visual studio 11.0.0\vc\bin
C/C++ Optimizing Compiler Version 17.00.51106.1 for x86

For me, I have then a compiler vc110 (Visual Studio) running in 32 bit on a
64 bit OS. Is it correct ?
In project properties, it is also written : Platform Toolset = Visual Studio
2012 (v110).

For the moment, as I have a 64-bit OS and as I want to use the platform x64
in Visual Studio to run my projects (I use x64 for all my other projects), I
have installed everything in 64 bit (CGAL 4.3, boost_1_55_0-msvc-11.0-64,
using CMake2.8.10.2. No need of Qt4 because I don't want to run CGAL demos)
but I'm not sure of what I've done because the compiler of Visual Studio is
32 bit ... (linked followed for 64-bit installation
http://www.cgal.org/download/windows.html )

I'm confused because I have both 32 bit (Visual Studio compiler) and 64 bit
(OS, platform x64 to build and run in Visual Studio) so I don't know if I
have to install in 32 bit all my libraries or in 64 bit ? I remember that at
the end, I want to build and run my project in Visual Studio with the
Solutions Platform x64. Could you help me for this ?


Last question : currently I have 47 linked errors due to the GMP library (in
CGAL_CORE) when I want to build ALL_BUILD. Maybe the prebuild files of GMP
library are not in 64 bit ( I have to check that ) but my question is : in
the properties of ALL_BUILD file I can't add libgmp-10.lib to the input
library (in the linker options) because it's not a project (and I have no
access to the linker options) so I can't get rid of these errors. Is it a
problem for building the CGAL library ? Or can I just ignore them and now I
create my VS project and in this project I add libgmp-10.lib to the input
library (in the linker options) ?

Thanks for your time and help,

Audrey
