====== Installation of Gblocks ======

===== Additional libraries ===== 

The ''ia32-libs'' package is necessary to run Gblocks on a x86_64 operating system. This should be covered if you start a server from scratch with these [[xfcegui_impilo_8.04|instructions]]. If you are installing on another Ubuntu server, do this:

<code>
% sudo apt-get -y install lib32-libs
</code>

===== Procedure =====

After looking, Gblocks source code is not available but a Linux executable is available from the web site. Here is the procedure to install GBlocks in Impilo:

  * The archive with the executable is downloaded from the web in ''/home/bioubuntu'', decompressed and the new folder moved in ''/opt/bio/sources''.

  * This folder should belong to ''root'' and its permissions should be set to ''755''.

<code bash>
% sudo chown -R root:root /opt/bio/sources/Gblocks_0.91b
% sudo chmod -R 755 /opt/bio/sources/Gblocks_0.91b
</code>

  * Once you are in ''/opt/bio/sources/Gblocks_0.91b'', simply create a symbolic link from the executable toward a location found in ''$PATH'':

<code bash>
% sudo ln -s /opt/bio/sources/Gblocks_0.91b/Gblocks /usr/local/bin/gblocks
</code>
