This how-to covers building IPFire from source code, creating a development environment that can be used to create new packages and make changes.
When building a development environment, you should be aware that:
You require a system with a common Linux distribution. Fedora, Ubuntu, or even IPFire itself will work.
You may have to change some minor things on your system and install several packages. There are some tips for common distributions. If your own distro is missing, feel free to add it here.
Next, grab the source code tarballs of every upstream package (~500MB):
In order to speed up compilation, you can download the first stage of the toolchain. This is recommended to do.
The build process automatically uses all available CPUs on the system to speed up the build as much as possible.
Start the build with:
Easy, isn't it? But this process will now take several hours...
Known to work: IPFire 2.x
These packages will be required:
pakfire install -y git make
IPFire can't build the toolchain, so you will have to use the precompiled version.
After git checkout and source download you also need to download the toolchain.
Known to work: Fedora Core 5, Fedora Core 6, Fedora 7-17 und Centos 5.1
These packages will be required, too:
yum install git gcc byacc make wget binutils bison patch texinfo gcc-c++ glibc-static which autoconf automake
Known to work: SuSE Linux 9.3, OpenSuSE 10.3
These packages will be required, too: git, gcc, make, patch, bzip2, bison
Install these packages with "yast".
Known to work: Debian 4.0R1, Debian 5.0, Debian 7.0, Debian 8.0
These packages will be required, too: git-core, gcc, g++, realpath, make, patch, bzip2, byacc, python-urlgrabber, bison, gawk, texinfo, autoconf, automake
Install these packages with:
apt-get install git-core gcc g++ realpath make patch bzip2 byacc python-urlgrabber bison gawk texinfo autoconf automake
aptitude install git-core gcc g++ realpath make patch bzip2 byacc python-urlgrabber bison gawk texinfo autoconf automake
There is a Symlink "/bin/sh" that points to "/bin/dash". This will cause an error if you compile glibc. Please change "/bin/sh" to "/bin/bash".
Ubuntu 11.04 needs some additional symlinks to asm header and glibc:
ln -s /usr/include/asm-generic /usr/include/asm ln -s /usr/lib/i386-linux-gnu/libc.so /usr/lib/libc.so
Known to work: Ubuntu 6.06 LTS - Ubuntu 11.04
These packages will be required, too: git-core, g++, realpath, patch, byacc, make, python-urlgrabber, autoconf, automake. Install them with apt-get or aptitude.
It also makes sense to install the package ccache to speed up compilation. If you made minor changes only that code will be compiled, the rest will be taken from the ccache.
Kown to work: simple i686 core installation
These packages will be required too:
pacman -S git gcc make patch urlgrabber bison gawk texinfo
First buildtime in VirtualBox(2 cores (2x2.1Ghz), 1GB Ram) ~12 hours, second buildtime just ~40 minutes.
The test machine was an Athlon XP 2000+ with 1.75 GB of RAM. Note that between the first and second build there only has been a "./make.sh clean" just to test ccache.
Nowadays, in 2014, build time has dropped to about 3 hours and 45 minutes, which is more than twice as fast as a little over a decade ago when the benchmarks you can see above where done on an AMD Athlon XP 2000+.
The new build time is from a laptop with an Intel Core i7 3612QM, 8GB of RAM and Linux Mint 16 x64 KDE.
