Step-by-Step 32bit Chroot Compile

Base 32 bit chroot setup

On Debian, bootstrap your 32bit chroot:

$ sudo debootstrap --arch i386 lenny /var/chroot/lenny-ia32 http://ftp.debian.org/debian/

Or, for sid:

$ sudo debootstrap --arch i386 sid /var/chroot/sid-ia32 http://ftp.debian.org/debian/

Once done, make sure you have your schroot entry set properly, mine looks like this

[lenny]
description=Debian lenny (stable)
location=/var/chroot/lenny-ia32
priority=3
groups=dzonatas,root
root-groups=root
aliases=stable,ia32
personality=linux32
type=plain
run-setup-scripts=true
run-exec-scripts=true

[sid]
description=Debian sid (unstable)
location=/var/chroot/sid-ia32
priority=3
groups=dzonatas,root
root-groups=root
aliases=unstable,default,ia32
personality=linux32
type=plain
run-setup-scripts=true
run-exec-scripts=true

Now you can log into your chroot to setup the base packages:

$ sudo linux32 schroot -c lenny -u root

Or, for sid:

$ sudo linux32 schroot -c sid -u root

Initialize the packages:

$ apt-get update

Install these packages:

$ apt-get install python g++ subversion unzip bzip2 libx11-dev libxrender-dev libgl1-mesa-dev libxft-dev libxrandr-dev libxcursor-dev libglu-dev libsdl-dev libgtk2.0-bin

For sid, you can just install cmake:

apt-get install cmake

For lenny, you have to modify /etc/apt/sources.list to insert squeeze into the list in order to get version 2.8+. It should look like:

deb http://ftp.debian.org/debian lenny main
deb http://ftp.debian.org/debian squeeze main

Then you can do:

$ apt-get install cmake

Sources Setup

Login to your chroot as a regular user:

$ sudo linux32 schroot -c lenny

Or, for sid:

$ sudo linux32 schroot -c sid

We can use the /tmp directory for this example, and download the sources.

$ cd /tmp
$ svn export https://svn.secondlife.com/svn/linden/projects/2009/snowglobe/trunk snowglobe
$ cd snowglobe
$ ln -s . linden
$ . doc/asset_urls.txt
$ wget $SLASSET_LIBS_LINUXI386
$ wget $SLASSET_ART
$ wget $SLASSET_MD5
$ unzip slviewer-artwork*zip
$ tar xzf slviewer-linux-libs*tar.gz

Run the Compile

$ cd indra
$ ./develop.py
$ cd viewer-linux-i686-relwithdebinfo
$ make

After that completes, you should have a packaged compile in newview/Snowglobe-i686-1.4.0.0.tar.bz2

Standalone 64 bit Compile: Debian Lenny/Squeeze AMD 64

Here are my notes about the compilation experience:

Lenny comes with cmake 2.6.0, but the experimental version is required:

sudo apt-get install -t sid cmake

Specific cmake builds wouldn't be needed if an universal binary was used, instead.

Downloaded and unpacked Snowglobe source (1.2.4.3008). Not gonna worry about git/hg/svn matters for this annotation.

Downloaded related files as specified in doc/asset_urls.txt: MD5, ART, LIBS_LINUXI386 (see above 32bit compile)

$ cd indra
$ ./develop.py --standalone -m64 configure
$ cd viewer-linux-x86_64-relwithdebinfo
$ make secondlife-bin

Issues:

• SNOW-240 At this time there is no jsoncpp debian package, so configure fails on this. Downloaded and compiled from sources noted in jira issue. Copied include files to /usr/local/include and libs to /usr/local/lib for temporary fix.
• SNOW-362 build error: 'skip' is not a member of 'tut::test_result' (see jira for questions and recommended patch)
• SNOW-285 build error: llqtwebkit.h: No such file or directory -- Despite this being a dependency, it should have made the configure fail like above in SNOW-240. The configure failure message could point to a wiki page to resolve the dependency (like an extra deb package for Debian).
• Somewhere in the attempts to build llqtwebkit, the /usr/lib/libGL.so file got deleted. I can pinpoint here because other programs worked (X, wine, monovida, etc) up until that moment. Very strange for that to happen, yet not totally unexpected (from other people's experience with qt-webkit). The older NVidia drivers that have Xgl support didn't have a deb package, so qt-webkit thought it could overwrite the GL files. Blind installs, like this issue, is exactly what the Debian-Way tries to avoid. I eventually avoided the llqtwebkit build entirely and just used the pre-built 32bit version for now. These plugins could be downloaded by a debian package separate from this build since it really isn't required to build and run secondlife-bin (thanks to LLMediaPlugin work).
• Upgrade to NVidia 190.42 drivers the Debian-Way.

With the above issues resolved, you can install the built files. Normally, a "make package" would package them for you, yet since this is a "standalone" version this means it is assumed some pieces that were normally put into the package are already installed somewhere else rather than being a static build with secondlife-bin. The "make package" works if you built the plugins.
