Chapter 12. Preparing Xorg and Support Libraries

Libdrm-2.4.129

Introduction to Libdrm

Libdrm provides a userspace library for accessing the direct rendering manager (DRM) 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 12.4 platform.

libdrm Dependencies

Recommended

Xorg7 Libraries (for Intel KMS API support required by Mesa)

Optional

"cairo" (for tests), CMake-4.1.3 (could be used to find dependencies without pkgconfig files), docbook-xml-4.5, docbook-xsl-nons-1.79.2, docutils-0.22.3, and libxslt-1.1.43 (to build manual pages), "libatomic_ops" (required by architectures without native atomic operations), "valgrind", and CUnit (for AMDGPU tests)

Installation of Libdrm

Prepare libdrm by running the following commands: 

meson setup build --prefix=/usr    \
            --buildtype=release   \
            -D udev=true          \
            -D valgrind=disabled

Now Build the package, issue: 

ninja -C build

To check the results, issue: 

ninja -C build test

Now Install, as the root user: 

ninja -C build install

Command Explanations

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

-D valgrind=disabled: This parameter disables building libdrm with valgrind support. This fixes building some packages that use libdrm. Change this parameter to "enabled" (or remove it) if you need support for valgrind.
