Chromium

The Ubuntu packaging branch is located in LP: lp:chromium-browser

There's a PPA: https://edge.launchpad.net/~chromium-daily/+archive/ppa

Sources

The upstream way:

GCLIENT_URL=http://src.chromium.org/svn/trunk/depot_tools/linux
CHROMIUM_URL=http://src.chromium.org/svn/trunk/src

# Checkout
svn co $GCLIENT_URL ./depot_tools
./depot_tools/gclient config $CHROMIUM_URL
./depot_tools/gclient sync

depot_tools is a very small set of scripts. Mostly wrappers for scons and svn.

gclient sync brings in several repositories (See src/DEPS)

The ubuntu package provides a get-orig-source target that can do branch caching.

bzr branch lp:chromium-browser
cd chromium-browser
./debian/rules get-orig-source LOCAL_BRANCH=../upstream/chromium-browser.svn

This will give you a fresh snapshot. You can also use 'get-current-source' to get the one needed to build the branch as it is.

64bit

There's no native 64bit support. The salute comes from ia32libs, well, sort of...

Upstream: http://code.google.com/p/chromium/wiki/LinuxBuild64Bit

Status in Ubuntu: (WIP)

- All: Build-deps += ia32-libs, lib32z1-dev

- Jaunty:
   - needs a bunch of symlinks for lib{gio-2.0,gdk-x11-2.0,atk-1.0,gdk_pixbuf-2.0,pangocairo-1.0,
                                       pango-1.0,pangoft2-1.0,gobject-2.0,gmodule-2.0,glib-2.0,
                                       gtk-x11-2.0}.so

- Intrepid:
   - same symlinks as jaunty
   - symlinks for lib{cairo,freetype,fontconfig,X11,Xrender,Xext}.so

- Hardy:
   - same symlinks as intrepid
   - nss32
   - nspr32

For the missing symlinks, the symptom is:

/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.3.3/../../../libgtk-x11-2.0.so when searching for -lgtk-x11-2.0

/usr/bin/ld: cannot find -lgtk-x11-2.0
collect2: ld returned 1 exit status

because /usr/lib32/libgtk-x11-2.0.so is missing:
