/** \page compiling Compiling OpenMesh
\section compilers Tested compilers
%OpenMesh has been successfully tested for the following operating
systems / compilers. This is only a list of tested compilers.
More might be supported but are not tested. Make sure that your compiler
supports at least C++11
Linux
gcc >= 6.3
clang >= 3.3
Windows
Microsoft Visual Studio 2015
Microsoft Visual Studio 2017
Tested MacOS X Compilers
XCode
\section req_libs Required libraries (Only if you want to build the included Apps)
Install the following external libraries / frameworks if you want to use the included Applications:
\section build_systems Chosing build system
%OpenMesh can be built using the cmake build system.
\section sec_compiling_unix Unix
\subsection linux_using_cmake 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
\warning If your compiler does not support c++11 natively, you might have to enable it by changing the cmake call to: cmake .. -DCMAKE_CXX_FLAGS=-std=c++98
You can choose the build type by using cmake with the flag -DCMAKE_BUILD_TYPE=(Debug|Release) The default is: Release
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
\note When you link against the static libraries of OpenMesh and get the error "can not be used when making a
shared object; recompile with -fPIC" you need to add "-fPIC" to the CMAKE_CXX_FLAGS. (This is usually added automatically)
\section sec_compiling_windows Windows
\subsection windows_using_cmake Compiling OpenMesh using CMake
Building OpenMesh on Windows requires cmake to generate the project files for Visual Studio.
Get Visual Studio ( 2015-2017 )
Extract %OpenMesh source code.
Get all required libraries and install them ( including headers! ).
Start the cmake gui and open the %OpenMesh toplevel directory as source directory
Choose a build directory (e.g. create a directory called "build" in OpenMesh's root folder)
Click on configure .... If any libraries are left unconfigured, you can adjust the path manually. Rerun configure until everything is configured correctly.
Attention: Some build variables are only visible in advanced view mode. Select Visual Studio 9 (2008), Visual Studio 10(2010), Visual Studio 11 (2012), Visual Studio 12 (2013) (Depending on your version) as
generator.
Click generate to create the visual studio project files
You can now find a Visual Studio solution file (OpenMesh.sln) in the build directory you chose in cmake
Now you can build %OpenMesh from within Visual Studio using the newly created project file.
\section sec_compiling_macosx MacOS X
Download and install required libraries as stated above.
You can download %OpenMesh's sources from www.openmesh.org or check out the latest repository via GIT: https://www.graphics.rwth-aachen.de:9000/OpenMesh/OpenMesh.
\subsection mac_using_cmake Compiling OpenMesh using CMake
We recommend you to use CMake >= 3.7 as build system. This can also easily be installed
via MacPorts as well as the Qt >= 5.6 library which is used for some example applications
in %OpenMesh.
Once installed, change to %OpenMesh's root directory and create a directory
named e.g. "buildDebug" (assuming you want to build with debug symbols).
Then type in the following command to initially set up the build environment:
cmake .. ## Generates the appropriate Makefiles
Note: If the build directory is not a subdirectory of %OpenMesh's root folder, replace ".." with %OpenMesh's
absolute (or relative) path.
In order to manually set specific build variables, just type:
ccmake . ## Configure build environment
This opens the CMake configure tool. Change the CMAKE_BUILD_TYPE variable to "Release" in order to prepare build
for release configuration. Now, when everything is set up, just type:
make ## Build %OpenMesh
And optionally:
make doc ## Build %OpenMesh's documentation
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.
