Natty Narwhal (11.04)

Feel free to edit this page if there's something missing.

To compile Nouveau DDX from Git, at least these packages are necessary: [[!format txt """ libudev-dev xserver-xorg-dev x11proto-fonts-dev x11proto-video-dev x11proto-xf86dri-dev """]] To compile the Gallium 3D driver from Git, these packages are necessary: [[!format txt """ xutils-dev x11proto-gl-dev x11proto-dri2-dev libdrm-dev libxext-dev libxdamage-dev libxfixes-dev libexpat1-dev libxt-dev libxmu-dev libxi-dev libegl1-mesa-dev flex bison libxvmc-dev """]] You will also need to pull some packages in from oneiric. To do this, first add oneiric to your sources (such as by making a file in /etc/apt/sources.list.d or using system software sources selection). Then, in order to make sure that you don't upgrade wholesale to this unreleased version, pin its priority in /etc/apt/preferences:

[[!format txt """

You will need to remove this (or change oneiric to psychedelic or

whatever Ubuntu 12.04 gets named) when you want to dist-upgrade to

oneiric; the do-release-upgrade script won't change it for you (or

know what went wrong)

Explanation: Don't install oneiric packages by default Package: * Pin: release a=oneiric Pin-Priority: 99 """]] You might also need to increase a limit in APT to handle multiple releases:

[[!format txt """ echo 'APT::Cache-Limit "125165824";' > /etc/apt/apt.conf.d/massive """]] Then, you can pull in selected packages from oneiric only, using the '-t' flag to apt-get:

[[!format txt """ sudo apt-get -t oneiric install libdrm2 x11proto-gl-dev x11proto-dri2-dev """]] Be sure to install the natty versions first, otherwise dependencies could unnecessarily come from oneiric instead of natty.

To compile 32-bit on a 64-bit system: [[!format txt """ libc6-dev-i386 """]] This package may be needed when you get errors about R300 and R600 drivers: [[!format txt """ llvm llvm-dev llvm2.8-dev """]] Compiling libdrm needs this package: [[!format txt """ dh-autoreconf """]] Most things here also apply to Maverick Meerkat (10.10).

Intrepid Ibex (8.10)

To compile latest 2D driver from git repository in Ubuntu 8.10, these dependencies should be installed: [[!format txt """ git-core libpthread-stubs0-dev autoconf libtool xorg-dev mesa-common-dev """]] And for Gallium 3D driver in addition to those listed above, these packages should be installed: [[!format txt """ xutils-dev build-essential """]] Also, dri2proto headers from git repository are needed for 3D driver: [[!format txt """ git clone git://anongit.freedesktop.org/xorg/proto/dri2proto cd dri2proto; ./autogen.sh sudo make install """]] If 3D driver doesn't load this section should be added to the end of /etc/X11/xorg.conf: [[!format txt """ Section "DRI" mode 0666 EndSection """]]

Gutsy Gibbon (development branch) (7.10)

As of 07/Jul/2007 on 2.6.22-7-generic it is not necessary to comment out vm_insert_pfn.

Feisty Fawn (7.04)

When making nouveau.ko and drm.ko make will complain when compiling linux-core/drm_compat.c.

It appears that this is because the kernel which shipped with Feisty is not really 2.6.20 but 2.6.20 + some bits from 2.6.21 including vm_insert_pfn, the drm needs vm_insert_pfn so when not present supplies its own copy, Ubuntu already supplies vm_insert_pfn but advertises itself as 2.6.20 conflicting with the drm build assumptions.

The end result of this is the Ubuntu kernel headers already have a definition for vm_insert_pfn and this drm supplied function in linux-core/drm_compat.c can be commented out to read something like;

[[!format txt """ /static int vm_insert_pfn(struct vm_area_struct vma, unsigned long addr, unsigned long pfn) { int ret; if (!drm_pte_is_clear(vma, addr)) return -EBUSY; ret = io_remap_pfn_range(vma, addr, pfn, PAGE_SIZE, vma->vm_page_prot); return ret; }*/ """]] Barring other problems make should complete.

As of 28/Apr/2007 works for me on 2.6.20-15-generic.

Unresolved / Undefined Symbols

If you are experiencing problems building nouveau, make sure that anything matching nvidia-glx is completely removed. Open Synaptic and make sure that anything related to nVidia isn't laying around in Residual Config.
