h1. Build dependencies installation

*Replicant can only be built on 64 bit x86 architectures, building on 32 bit x86 systems is no longer supported.*
However, some prebuilt tools are still 32 bit x86 executables and some host tools are generated as 32 bit x86 executables.

h2. Replicant 6.0

h3. Debian-based systems

*Trisquel 7.0*

*Tweaks*

* If the packages manager complains about @lib32readline5-dev@ being missing, it has to be replaced with @lib32readline-gplv2-dev@ in the command line.
* If the @/usr/lib/zconf.h@ header is missing, a symlink has to be created:
<pre>
ln -s /usr/include/x86_64-linux-gnu/zconf.h /usr/lib/zconf.h
</pre>
* If errors messages about incompatible library versions are shown, some symlinks have to be created. For instance:
<pre>
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
</pre>

h3. Arch Linux-based systems

*Parabola*

Base packages (from the Parabola repositories) installation:
<pre>
pacman -S --needed core/bison core/flex core/make core/ncurses core/xz core/zlib extra/bc extra/git extra/gperf extra/gperftools libre/jdk7-openjdk extra/openjdk7-src libre/jre7-openjdk extra/wget extra/zip community/squashfs-tools community/pngcrush libre/unzip
</pre>

Some additional repositories are required to retrieve some of the build dependencies.

To enable those repositories, the following should be added to @/etc/pacman.conf@:
<pre>
[libre-multilib]
Include = /etc/pacman.d/mirrorlist

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

For these changes to take effect, the packages database should be updated:
<pre>
pacman -Syu
</pre>

Additional packages installation:
<pre>
pacman -S --needed multilib/lib32-glibc multilib/gcc-multilib multilib/lib32-readline multilib/lib32-ncurses multilib/lib32-zlib
</pre>

*Tweaks*

* repo may complain about experimental python 3 support: python 2 has to be set as default instead:
<pre>
ln -s /usr/bin/python2 /usr/local/bin/python
</pre>
