In this section, we describe how to configure, build, and install the pmp-library in detail.
The pmp-library uses CMake as its build configuration system. Version 3.0.2 or greater is required. The pmp-library requires a C++11-compliant compiler. We continuously build and test the pmp-library with the following compilers and operating systems:
| Operating System | Compiler |
|---|---|
| Linux | gcc 4.8.4, clang 3.9.0 |
| Mac OS-X | AppleClang 8.1.0 |
| Windows | Visual Studio 2015, 2017 |
Some parts of the pmp-library depends on the following third-party libraries:
| Library | Description | Version |
|---|---|---|
| Eigen | C++ linear algebra library | ≥ 3.3.7 |
| OpenGL | Open Graphics Library | ≥ 3.3 |
| GLEW | OpenGL Extension Wrangler Library | ≥ 2.1.0 |
| GLFW | Graphics Library Framework | ≥ 3.3 |
| ImGui | Immediate Mode GUI | ≥ 1.70 |
| Google Test | C++ Test Framework | ≥ 1.8.0 |
By default, we include the corresponding libraries using git submodules. Note that OpenGL and related dependencies are optional. They are only needed if you want to use the viewer classes. Google Test is optional as well and only required if you want to run the unit test suite.
The pmp-library relies on CMake as its build and
configuration system. CMake is a cross-platform build-system capable of
generating different build files (so-called generators) for a specific
platform, e.g., Makefiles for Linux/Unix, Xcode projects for Mac OS-X and Visual
Studio projects for Windows.
On the command line change to the top-level pmp-library directory, create a
build directory and run cmake:
cd pmp
mkdir build
cd build
cmake ..
The configuration procedure can be fine-tuned by specifying flags using the -D
option of cmake:
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_COMPILER=/usr/bin/g++
The command above would configure CMake to use release mode as its build type
and /usr/bin/g++ as its C++ compiler.
In order to compile the included examples configure CMake with
cmake -DWITH_EXAMPLES=true ..
Commonly used flags are shown below.
| Flag | Description |
|---|---|
CMAKE_BUILD_TYPE |
Specify the build type, e.g. Debug or Release. |
CMAKE_CXX_COMPILER |
Specify the compiler to be used. |
CMAKE_CXX_FLAGS |
Specify additional compiler flags, e.g. -DNDEBUG |
For additional information on using CMake and
customizing its configuration see
the CMake documentation.
After successful configuration pmp-library can be build using the chosen build system. For a Unix-like environment the default generator is Makefiles. In order to build pmp-library just call
make
from the top-level build directory. In order to build pmp in parallel use the
-j option of make:
make -j
The resulting library is named libpmp.so and
located in the current working directory.
In order to build the full HTML manual and reference documentation call
make doxygen
The resulting HTML documentation can be found in the docs/html/ sub-directory.
Note: this requires Doxygen to be installed. In order
to generate proper bibliographical references please install
BibTex as well.
In order to install pmp-library just call
sudo make install
Upon installation, both the library and headers will be installed to the
directory given via CMAKE_INSTALL_PREFIX, which defaults to /usr/local/ on
Unix-like systems. If you need to install to a custom location set the install
prefix during build configuration:
cmake -DCMAKE_INSTALL_PREFIX=<your custom path> ..
The library can be uninstalled using
make uninstall
To use the pmp-library in your own CMake-based projects simply include the
library by using find_package(pmp) and point CMake to the directory containing
the pmp-library CMake configuration file pmpConfig.cmake. This can be either
the pmp-library build directory
cmake -Dpmp_DIR=<path-to-pmp-build-directory>
or the installed version
cmake -Dpmp_DIR=<your custom path>/lib/cmake/pmp
This way, you can simply link your own target against pmp-library
target_link_libraries(your_target pmp)
Note: The usage described above is currently limited to the @ref core and
@ref algorithms modules of the pmp-library. If you want to use the @ref
visualization module you need to link your target against pmp_vis and its
dependencies: stb_image, imgui, glfw, glew, as well as your platform
OpenGL library. In this case, however, we recommend to use the project
template. See also
Quickstart.
By default, the pmp-libray uses 32-bit unsigned integers as internal index type to reference entities. However, if you need to process very large data sets this might not be sufficient. In this case, you can change the index type to be 64-bit by specifying
cmake -DPMP_INDEX_TYPE=64
during build configuration.
By default, the pmp-library uses float as Scalar type. In case you require
higher floating point precision you can change the Scalar type to double by
specifying
cmake -DPMP_SCALAR_TYPE=64
during build configuration.
In order to build the JavaScript applications using emscripten, download the SDK from https://github.com/kripken/emscripten and follow the installation instructions.
Next, source the environment setup script:
source <path_to_install_dir>/emsdk_env.sh
Create a build directory, run cmake, build, enjoy:
mkdir jsbuild
cd jsbuild
emconfigure cmake ..
make
