Installing NodeJS

Using precompiled .deb packages

Debian does not provide NodeJS within its Squeeze release, but it is available for Sid and to have it on the FoxBoard is mostly a matter or recompiling it.

To let you jump start into NodeJs development, we provide an archive of precompiled Debian packages for the FoxBoard.

Here are the instructions for downloading the archive to your FoxBoard, unpacking it and installing the debian packages:

tar xvf nodejs-foxboard-debs.tar
cd debs
dpkg -i `ls *.deb|grep -v dbg`
apt-get -f install
node -v

(with these instructions you will not install the dbg packages, which are big and mostly needed to debug NodeJS itself).

Compiling your own .deb packages

In order to provide the precompiled packages on Squeeze, we quite simply rebuilt Debian/Sid ones on the FoxBoard. The process does take some time to complete on your humble FoxBoard, but it is worth its while to document it in detail: Sid is a moving target, and some of you might well want to get the newer versions of NodeJS.

The first step required for rebuilding everything on the FoxBoard is to add a line

deb-src sid main contrib non-free

to your /etc/apt/sources.list file, so that apt-get source will know where to grab the source packages we need.

NodeJS is based on Javascript V8, which on Debian is packaged separately as libv8 to be shared with other packages (most notably, with Chromium).

NB: in the following instructions we refer to specific version numbers - these are likely going to be different by the time you need them, so please adjust the commands accordingly.

A dependency of libv8 is libev4, which we are going to rebuild first:

export CFLAGS="-march=armv5te"
apt-get source libev/sid
apt-get build-dep libev/sid
cd libev-4.04
cd ..
dpkg -i libev4*.deb libev-dev*.deb

Then it is time for libv8, which is the biggest package of the batch. Compilation completes correctly but the tests default timeout of 60 seconds is too short and they fail. Compiling with tests disabled we obtain the required package - after a few hours:

export CFLAGS="-march=armv5te"
export DEB_BUILD_OPTIONS="nocheck"
apt-get source libv8/sid
apt-get build-dep libv8/sid
cd libv8-
cd ..
dpkg -i libv8-3*.deb libv8-dev*.deb

Finally, we get to nodejs itself - again, tests exceed the timeouts, so we recompile without them:

export CFLAGS="-march=armv5te"
export DEB_BUILD_OPTIONS="nocheck"
apt-get source nodejs/sid
apt-get build-dep nodejs/sid
cd nodejs-0.4.11
cd ..
dpkg -i nodejs_0.4*.deb

In order to follow Debian policy, which looks for NodeJS modules under /usr/lib/nodejs, we also rebuild npm - the node package manager:

apt-get source npm/sid
apt-get build-dep npm/sid
cd npm-0.2.19
cd ..
dpkg -i npm*.deb

Et voilĂ , les jeux sont faits!

Installing from source

You might prefer building a newer version of Node or NPM, instead of relying on Debian packages which might be outdated. Since Node version 0.6.0 is just landed, here is the quick command list to compilation:

apt-get -y install libssl libssl-dev pkg-config
tar -zxf node-v0.6.0.tar.gz
cd node-v0.6.0
export CFLAGS="-march=armv5te"
export CCFLAGS="-march=armv5te"
./configure --without-snapshot
make install
curl | sh

Of course, compilation on the FoxBoard takes quite some time - be patient, and you will be rewarded!
