h1. Build Dependencies

In order to be able to build Replicant, you need to install some (free) software:

h2. Required Packages

* python 2.5-2.7
* bison
* flex
* git (git-core)
* gperf
* libncurses development headers (libncurses-dev)
* make (build-essential)
* mksquashfs (squashfs-tools)
* openjdk 6
* pngcrush - the build process will complain if it is not installed but builds will complete.
* wget (or curl)
* zip
* zlib development headers (zlib1g-dev)
* lzma


h3. Additional requirements for amd64


* libc6-dev-i386
* gcc-multilib
* g++-multilib 
* lib32z1-dev 
* lib32readline5-dev
* lib32ncurses5-dev
* 32-bit compatibility libraries
* 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

h2. Command line installation

h3. Trisquel/Ubuntu/Debian

Required packages:
<pre>
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
</pre>

Additional requirements for amd64:
<pre>
apt-get install libc6-dev-i386 gcc-multilib g++-multilib lib32z1-dev lib32readline5-dev lib32ncurses5-dev 
</pre>

h3. Parabola/Arch

Add the following to /etc/pacman.conf (it should be safe for freedom since lukeshu is part of the parabola community and pcr is a parabola repository):
<pre>
[pcr]
SigLevel = PackageRequired
Include = /etc/pacman.d/mirrorlist

[~lukeshu]
Include = /etc/pacman.d/mirrorlist
</pre>

Required packages :
<pre>
pacman -S core/bison core/flex extra/gperftools core/ncurses community/squashfs-tools pcr/openjdk6-old extra/wget extra/zip core/zlib core/xz ~lukeshu/pngcrush extra/gperf extra/bc
</pre>

Additional requirements for amd64:
Uncomment or add the following repository in /etc/pacman.conf:
<pre>
[multilib]
SigLevel = PackageRequired
Include = /etc/pacman.d/mirrorlist
</pre>

<pre>
pacman -S multilib/lib32-glibc multilib/gcc-multilib multilib/lib32-readline multilib/lib32-ncurses multilib/lib32-zlib
</pre>
