| 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. libdrm is a low-level library, typically used by | |
| graphics drivers such as the Mesa DRI drivers, the X drivers, libva | |
| and similar projects. New functionality in the kernel DRM drivers | |
| typically requires a new libdrm, but a new libdrm will always work | |
| with an older kernel. | |
| Compiling | |
| --------- | |
| libdrm is a standard autotools package and follows the normal | |
| configure, build and install steps. The first step is to configure | |
| the package, which is done by running the configure shell script: | |
| ./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. |
