Installation Instructions ========================= Prerequisites ------------- To build from source, you will need: * A relatively modern C++ compiler (GCC, Clang, and MSVC are known to work). * [Meson](http://mesonbuild.com/), which depends on [Python](http://python.org/). This is a brief overview of building this project with meson. See the meson documentation for more detailed information. Configuration ------------- The build is configured with the `setup` command, which creates a new build directory with the given name: meson setup build Some environment variables are read during `setup` and stored with the configuration: * `CXX`: Path to C++ compiler. * `CXXFLAGS`: C++ compiler options. * `LDFLAGS`: Linker options. However, it is better to use meson options for configuration. All options can be inspected with the `configure` command from within the build directory: cd build meson configure Options can be set by passing C-style "define" options to `configure`: meson configure -Dcpp_args="-march=native" -Dprefix="/opt/mypackage/" Note that some options, such as `strict` and `werror` are for developer/maintainer use only. Please don't file issues about anything that happens when they are enabled. Building -------- From within a configured build directory, everything can be built with the `compile` command: meson compile Similarly, tests can be run with the `test` command: meson test Meson can also generate a project for several popular IDEs, see the `backend` option for details. Installation ------------ A compiled project can be installed with the `install` command: meson install You may need to acquire root permissions to install to a system-wide prefix. For packaging, the installation may be staged to a directory using the `DESTDIR` environment variable or the `--destdir` option: DESTDIR=/tmp/mypackage/ meson install meson install --destdir=/tmp/mypackage/
