Introduction to libdrm

libdrm provides a user space library for accessing the DRM, direct rendering manager, on operating systems that support the ioctl interface. libdrm is a low-level library, typically used by graphics drivers such as the Mesa DRI drivers, the X drivers, libva and similar projects.

This package is known to build and work properly using an LFS-11.0 platform.

Package Information

libdrm Dependencies



Cairo-1.17.4 (for tests), CMake-3.21.2 (could be used to find dependencies without pkgconfig files), docbook-xml-4.5, docbook-xsl-1.79.2, docutils-0.17.1, and libxslt-1.1.34 (to build manual pages), libatomic_ops-7.6.10 (required by architectures without native atomic operations), Valgrind-3.17.0, and CUNIT (for AMDGPU tests)

User Notes:

Installation of libdrm

Install libdrm by running the following commands:

mkdir build &&
cd    build &&

meson --prefix=$XORG_PREFIX \
      --buildtype=release   \
      -Dudev=true           \
      -Dvalgrind=false      &&

To check the results, issue ninja test.

Now, as the root user:

ninja install

Command Explanations

--buildtype=release: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.

-Dudev=true: This parameter enables support for using Udev instead of mknod.

-Dvalgrind=false: This parameter disables building libdrm with valgrind support. This fixes building sysprof and other packages that use libdrm. Change this parameter to "true" if you need support for valgrind.
