The meson build system is much faster, and offers a +slightly different interface, but otherwise provides an equivalent feature set. + +To use it: + + meson builddir/ + +By default this will install into /usr/local, you can change your prefix +with --prefix=/usr (or `meson configure builddir/ -Dprefix=/usr` after +the initial meson setup). + +Then use ninja to build and install: + + ninja -C builddir/ install + +If you are installing into a system location you will need to run install +separately, and as root. + + +Alternatively you can invoke autotools configure: + + ./configure + +By default, libdrm will install into the /usr/local/ prefix. If you +want to install this DRM to replace your system copy, pass +--prefix=/usr and --exec-prefix=/ to configure. If you are building +libdrm from a git checkout, you first need to run the autogen.sh +script. You can pass any options to autogen.sh that you would other +wise pass to configure, or you can just re-run configure with the +options you need once autogen.sh finishes. + +Next step is to build libdrm: + + make + +and once make finishes successfully, install the package using + + make install + +If you are installing into a system location, you will need to be root +to perform the install step. |
