h1. Build Dependencies Installation In order to be able to build Replicant, you need to install some (free) software: h2. Required Packages * python 2.x * bison * flex * git * gperf * libncurses development headers * make * gcc, g++ * mksquashfs * openjdk 6 * pngcrush * wget * zip * zlib development headers * lzma h3. Additional requirements for 64 bit computers * 32 bit libncurses * 32 bit libreadline * 32 bit libc6 headers * 32 bit zlib * gcc, g++ multilib support h2. Command line installation h3. Trisquel/Debian/Ubuntu Required Packages:
apt-get install  bison flex git-core gperf libncurses-dev build-essential squashfs-tools openjdk-6-jre openjdk-6-jdk pngcrush wget zip zlib1g-dev lzma
Additional requirements for 64 bit computers:
apt-get install libc6-dev-i386 gcc-multilib g++-multilib lib32z1-dev lib32readline5-dev lib32ncurses5-dev 
On Debian sid, multi-arch i386 has to be enabled and the following is also required:
apt-get install zlib1g-dev:i386
* If the packages manager complains about @lib32readline5-dev@ being missing, replace it with @lib32readline-gplv2dev@ in the command line. * If the @/usr/lib/zconf.h@ header is missing, you will have to create a symlink there:
sudo ln -s /usr/include/x86_64-linux-gnu/zconf.h /usr/lib/zconf.h
* If you see errors about incompatible library versions, you may need some symlinks. For example:
sudo ln -s /usr/lib32/libstdc++.so.6.0.14 /usr/lib32/libstdc++.so
sudo ln -s /usr/lib32/libz.so.1.2.3.4 /usr/lib32/libz.so
h3. Parabola/Arch h4. For 32bit and 64 bit installations Then update all packages::
pacman -Syu
Then install the required Packages:
pacman -S core/bison core/flex core/make core/ncurses core/xz core/zlib extra/bc extra/git  extra/gperf extra/gperftools extra/jre7-openjdk extra/jdk7-openjdk extra/wget extra/zip community/squashfs-tools libre/pngcrush
Also set python2 as the default for now. (Else repo will issue such warning: "warning: Python 3 support is currently experimental. YMMV.")
cd /usr/local/bin/
ln -s /usr/bin/python2 ./python
h4. Extra packages for 64bit installations. 64bit installations require more packages because some uttilities(like adb) are built for 32bit computers. Add the following repository in /etc/pacman.conf:
[multilib]
Include = /etc/pacman.d/mirrorlist
Then install the missing dependencies for 64bit:
pacman -S multilib/lib32-glibc multilib/gcc-multilib multilib/lib32-readline multilib/lib32-ncurses multilib/lib32-zlib
