1 libdrm - userspace library for drm 2 3 This is libdrm, a userspace library for accessing the DRM, direct 4 rendering manager, on Linux, BSD and other operating systems that 5 support the ioctl interface. The library provides wrapper functions 6 for the ioctls to avoid exposing the kernel interface directly, and 7 for chipsets with drm memory manager, support for tracking relocations 8 and buffers. libdrm is a low-level library, typically used by 9 graphics drivers such as the Mesa DRI drivers, the X drivers, libva 10 and similar projects. New functionality in the kernel DRM drivers 11 typically requires a new libdrm, but a new libdrm will always work 12 with an older kernel. 13 14 15 Compiling 16 --------- 17 18 libdrm has two build systems, a legacy autotools build system, and a newer 19 meson build system. The meson build system is much faster, and offers a 20 slightly different interface, but otherwise provides an equivalent feature set. 21 22 To use it: 23 24 meson builddir/ 25 26 By default this will install into /usr/local, you can change your prefix 27 with --prefix=/usr (or `meson configure builddir/ -Dprefix=/usr` after 28 the initial meson setup). 29 30 Then use ninja to build and install: 31 32 ninja -C builddir/ install 33 34 If you are installing into a system location you will need to run install 35 separately, and as root. 36 37 38 Alternatively you can invoke autotools configure: 39 40 ./configure 41 42 By default, libdrm will install into the /usr/local/ prefix. If you 43 want to install this DRM to replace your system copy, pass 44 --prefix=/usr and --exec-prefix=/ to configure. If you are building 45 libdrm from a git checkout, you first need to run the autogen.sh 46 script. You can pass any options to autogen.sh that you would other 47 wise pass to configure, or you can just re-run configure with the 48 options you need once autogen.sh finishes. 49 50 Next step is to build libdrm: 51 52 make 53 54 and once make finishes successfully, install the package using 55 56 make install 57 58 If you are installing into a system location, you will need to be root 59 to perform the install step. 60
