| libdrm - userspace library for drm |
| ---------------------------------- |
| |
| This is libdrm, a userspace library for accessing the DRM, direct rendering |
| manager, on Linux, BSD and other operating systems that support the ioctl |
| interface. |
| The library provides wrapper functions for the ioctls to avoid exposing the |
| kernel interface directly, and for chipsets with drm memory manager, support |
| for tracking relocations and buffers. |
| New functionality in the kernel DRM drivers typically requires a new libdrm, |
| but a new libdrm will always work with an older kernel. |
| |
| libdrm is a low-level library, typically used by graphics drivers such as |
| the Mesa drivers, the X drivers, libva and similar projects. |
| |
| |
| Compiling |
| --------- |
| |
| libdrm has two build systems, a legacy autotools build system, and a newer |
| meson build system. 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. |
