Compiling OpenMesh

Tested compilers

OpenMesh has been successfully tested for the following operating systems / compilers:

Linux	gcc 4.0.x gcc 4.1.x gcc 4.2.x gcc 4.3.x
Windows	Microsoft Visual Studio 2008
MacOS X (Panther, Tiger and Leopard)	gcc 4.0 gcc 4.2

Required libraries (Only for included Apps)

Install the following external libraries / frameworks if you want to use the included Applications:

OpenGL	http://www.opengl.org
Qt4	http://www.qtsoftware.com/downloads
GLEW	http://glew.sourceforge.net/

Chosing build system

OpenMesh can be built either using cmake or qmake (that already comes along with the qt framework) . We strongly recommend use of the cmake build system.

Unix

Compiling OpenMesh using CMake

In order to compile OpenMesh, create a directory named e.g. "build" in OpenMesh's root directory. Change to the newly created directory and type

cmake ..            ## Generates the appropriate Makefiles
make                ## Builds the project

You can choose the build type by using cmake with the flag
-DCMAKE_BUILD_TYPE=(Debug|Release)
The default is: Debug
Other flags are:
-DBUILD_APPS=OFF to disable build of applications and
-DCMAKE_INSTALL_PREFIX=<path> to specify the install path.
When calling make install cmake will install OpenMesh into this directory using the subdirectories lib/include/bin.

CMake builds both shared and static under Linux.

Everything will then be build in the Build subdirectory containing the libraries in lib and the binaries in bin.

There are some additional targets:
doc: Builds the Documentation
doc-install: Builds the Documentation and installs it

Compiling OpenMesh using QMake

In order to compile OpenMesh, enter following commands in OpenMesh's root directory:

qmake             ## Generates the appropriate Makefiles
make              ## Builds the project (use 'make debug' to build debug version)

Make sure to use Qt version 4 (some linux distributions
use the link qmake-qt4 against the executable).

Windows

Compiling OpenMesh using CMake

If you want to use cmake to build your Visual Studio 2008 solution file,
download and install CMake from www.cmake.org.
(Note: This is not mandatory since there are already VS2008 solution files included in OpenMesh).

Install the OpenGL Extension Wrangler Library (GLEW) from http://glew.sourceforge.net.

• Get Visual Studio 2008
• Extract OpenMesh source code.
• Get all required libraries and install them ( including headers! ).
• Get cmake for windows from http://www.cmake.org/cmake/resources/software.html
• Start the cmake gui and open the OpenMesh toplevel directory
• Choose a build directory
• Click on configure .... If any libraries are left unconfigured, you can adjust the path in the ui. Rerun configure until everything is configured correctly
• Click generate to create the visual studio project files
• You can now find a Visual Studio solution file in the build directory you chose in cmake
• Now you can build OpenMesh from within Visual Studio using the newly created project file.

Compiling OpenMesh using QMake

If you want to use qmake to build your Visual Studio 2008 solution file,
download and install the Qt4 framework from Trolltech.
(Note: This is not mandatory since there are already VS2008 solution files included in OpenMesh).

Install the OpenGL Extension Wrangler Library (GLEW) from http://glew.sourceforge.net.

Open OpenMesh\qmake\packages\packages.Windows in a text editor and change the include and library paths
for GLEW and GLUT such that they match the installed ones (see comments to find the right path entries).

• In Microsoft Visual Studio 2008 open Tools->Visual Studio command prompt
• Go to the folder of your application and call C:\qt4\bin\qmake.exe -r
• Open the resulting visual studio solution ( *.sln )
• Choose which build target to use ( Debug/Release )
• Choose Build solution from the build menu

MacOS X

Download and install required libraries as stated above. Because some of the examples depend on the GLEW library, it's recommended to install glew via the darwin portage system darwin ports.
If you have not installed it yet, follow the instructions given on their site in order to install it.
Type sudo port -v install glew to install glew headers and libraries. ( Darwin ports usually installs header files to /usr/local/include and libraries to /usr/local/lib. )

Compiling OpenMesh using CMake

If you're using cmake as preferred build system create a directory named e.g. in OpenMesh's root directory and change to it.

cmake ..            ## Generates the appropriate Makefiles
make                ## Builds the project (use 'make debug' to build debug version)

The mac application bundle will be found under "Build" in the recently created build folder. It automatically contains all needed shared objects (libs, fonts, textures, etc.).

CMake builds both shared and static under MacOS X.

Compiling OpenMesh using QMake

Adapt the header paths of at least GLEW (optional freetype, FTGL,...) in file OpenMesh/qmake/packages/packages.Darwin.

In order to compile and install OpenMesh, open a Terminal window and enter following commands in OpenMesh's root directory:

qmake -spec macx-g++       ## Generates the appropriate Makefiles
make                       ## Builds the project (use 'make debug' to build debug version)
