Beyond Linux® From Scratch (System V Edition) - Version 9.0

Chapter 25. X Libraries

libdrm-2.4.99

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-9.0 platform.

Package Information

libdrm Dependencies

Recommended

Xorg Libraries (for Intel KMS API support required by Mesa)

Optional

Cairo-1.16.0 (for tests), CMake-3.15.2 (could be used to find dependencies without pkgconfig files), docbook-xml-4.5, docbook-xsl-1.79.2 and libxslt-1.1.33 (to build manual pages), libatomic_ops-7.6.10 (required by architectures without native atomic operations), Valgrind-3.15.0, and CUNIT (for AMDGPU tests)

Installation of libdrm

Install libdrm by running the following commands: 

mkdir build &&
cd    build &&

meson --prefix=$XORG_PREFIX -Dudev=true &&
ninja

To check the results, issue ninja test. One test, 'threaded' in the nouveau subdirectory, is known to fail with a 30 second timeout.

Now, as the root user: 

ninja install

Command Explanations

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