Beyond Linux® From Scratch - Version 7.8

Chapter 25. X Libraries

libdrm-2.4.64

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-7.8 platform.

Package Information

libdrm Dependencies

Recommended

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

Optional

docbook-xml-4.5, docbook-xsl-1.78.1 and libxslt-1.1.28 (to build manual pages), and Valgrind-3.10.1

User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/libdrm

Installation of libdrm

Install libdrm by running the following commands: 

sed -e "/pthread-stubs/d" \
    -i configure.ac &&
autoreconf -fiv     &&

./configure --prefix=/usr \
            --enable-udev \
            --disable-valgrind &&
make

To check the results, issue make check. Tests may hang for unknown reasons. If nouveau threaded test hangs, you can disable it with sed -i 's/^TESTS/#&/' tests/nouveau/Makefile.in.

Now, as the root user: 

make install

Command Explanations

sed -e "/pthread-stubs/d" -i configure.ac: This sed removes dependency on libpthread-stubs package which is useless on Linux.

--enable-udev: This parameter enables support for using Udev instead of mknod.

--disable-valgrind: This parameter fixes a hard dependency on Valgrind.
