You will need

Sources:

  • libdrm-2.2
  • MesaLib-6.5.2
  • Kernel-2.6.16.18
  • libegl?

Process

The process requires both kernel space and user space software. You will need the kernel, the DRM/DRI and mesa source trees.

libdrm

These are the user space libs. Here is an example configure script to set some options for sandbox style compilation - where we don't want to install binaries on the host system. This is because we eventually want to cross compile for a target system.

I obtained the DRM source with git. 

cd
mkdir drm
cd drm
git clone git://anongit.freedesktop.org/git/mesa/drm

export ROOT=/home/rob/framebuffer/install
cd drm
./configure \
--prefix=$ROOT/usr \
--exec-prefix=$ROOT/usr \
--bindir=$ROOT/usr/bin \
--sbindir=$ROOT/usr/sbin \
--libexecdir=$ROOT/usr/lib \
--sysconfdir=$ROOT/etc \
--datadir=$ROOT/usr/share \
--localstatedir=$ROOT/var \
--mandir=$ROOT/usr/man \
--infodir=$ROOT/usr/info

make install

This create some files in /home/rob/framebuffer/install/usr/lib, and others.

Mesa

cd
mkdir mesa
cd mesa
cvs -d:pserver:anonymous@anoncvs.freedesktop.org:/cvs/mesa co Mesa

Need to patch the config file to make it install things in our install directory 

cd Mesa
export OD_INSTALL='/home/rob/framebuffer/install'
export PKG_CONFIG_PATH="$OD_INSTALL/usr/lib/pkgconfig"
sed -ri "s|INSTALL_DIR = .*$|INSTALL_DIR = $OD_INSTALL|" configs/default
sed -ri "s|DRI_DRIVER_INSTALL_DIR = .*$|DRI_DRIVER_INSTALL_DIR = $OD_INSTALL" configs/default
sed -ri "s|DRM_SOURCE_PATH=.*$|DRM_SOURCE_PATH = $OD_INSTALL/../drm|" configs/default
make realclean

All going well you will end up with a bunch of .o files in your ~/drm/drm/linux-core directory.

Now you need to build mesa linking against these .o files. 

cd ~/mesa/Mesa-6.5.2

We need to edit the config to point to the DRM modules. And make it. 

make linux-solo

dri

cd
mkdir kernel
cd kernel
wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.16.18.tar.bz2
tar xjf linux-2.6.16.18.tar.bz2
cd ~/drm/drm/linux-core
make LINUXDIR=~/kernel/linux-2.6.18/
