Compiling ratbagd
|

|

./autogen.sh && ./configure --prefix=/usr/ --libdir=/usr/lib64
|
||||
make
|
||||
sudo make install
|
||||
ratbagd uses the meson build system (see http://mesonbuild.com) which in
|
||||
turn uses ninja to invoke the compiler (`ninja` may be `ninja-build` on your
|
||||
distribution). From a fresh git checkout, run the following commands to init
|
||||
the repository:
|
||||
|
||||
Depending on your distribution, you can omit the --libdir argument. Fedora
|
||||
and related require it, Debian and related do not.
|
||||
meson builddir --prefix=/usr/
|
||||
|
||||
And to build or re-build after code-changes, run:
|
||||
|
||||
ninja -C builddir
|
||||
sudo ninja -C builddir install
|
||||
|
||||
Note: 'builddir' is the build output directory and can be changed to any
|
||||
other directory name. To set configure-time options, use e.g.
|
||||
|
||||
mesonconf builddir -Denable-documentation=no
|
||||
|
||||
Run 'mesonconf builddir' to list the options.
