====== Installing LTIB (Linux Target Image Builder) ======
===== Preparation =====
==== Requirements ====
This guide is based on an Ubuntu system from version 10.04. It can either be a native operating system or an installation in a virtual machine.

==== Download installation sources ====
Either copy the source file (L2.6.35_11.01.00_ER_source_tq.tar.gz) from the supplied CD or download the LTIB TQMa35 package, which contains the source file, from 
[[https://www.tq-embedded.com/en/Pim/Product-collection/Embedded-module-TQMa35|the TQMa35 product page]] under Downloads.\\
Extract the source code with:
<code bash>
user@ubuntu:~/source$ tar -xvf L2.6.35_11.01.00_ER_source_tq.tar.gz
</code>

==== Installing required packets ====
<code bash>
sudo apt-get update
sudo apt-get install build-essential zlib1g-dev rpm libncurses5-dev m4 bison liblzo2-dev uuid-dev tcl
</code>

==== Configuring sudo ====
The LTIB installation script runs several commands with ''sudo'' where the user should not be prompted for a password. ''sudo'' without password must be configured for the current user to execute the script correctly. Therefore with 
<code bash>
sudo visudo
</code>
the file /etc/sudoers is opened for editing.

The following line should be inserted in the file, where ''user'' has to be changed to your user name:
<code>
# Allow user to run commands for ltib.
user ALL = NOPASSWD: /usr/bin/rpm, /opt/freescale/ltib/usr/bin/rpm
</code>
Save with Ctrl+o, then close with Ctrl+x.

==== Create installation directory ====
Change to directory /opt, create a new directory for LTIB and assign to the current user.
<code bash>
user@ubuntu:/$ cd /opt/
user@ubuntu:/opt$ sudo mkdir ltib_iMX35
user@ubuntu:/opt$ sudo chown user:user ltib_iMX35/
</code>

===== Perform installation =====
Run the install script in the directory of the installation sources:

<code bash>
user@ubuntu:~/source/L2.6.35_11.01.00_ER_source_tq$ ./install
</code>

Read and accept the EULA.
Enter ''/opt/ltib_iMX35'' as choice of directory.
Then change to directory ''/opt/ltib_iMX35/ltib''.

===== Set LTIB proxy =====
Depending on the local Internet connection an HTTP proxy has to be set in the file ltib/.ltibrc and the use of the proxy when accessing the Global Package Pool.

<code>
%http_proxy
http://proxy.address:port

%gpp_proxy
1
</code>

===== Configure LTIB =====
<code bash>
user@ubuntu:~$ cd /opt/ltib_iMX35/ltib
user@ubuntu:/opt/ltib_iMX35/ltib$ ./ltib
</code>

<WRAP round info>Should there be a problem with Ubuntu 11.04, indicating that glibc-devel and zlib are not detected as installed, the file ltib/bin/Ltibutils.pm must be edited.


**For a 32-bit system:**

**For a 64-bit system:**
<code>
Line 563:     'glibc-devel'    => sub { -f '/usr/lib/libm.so' || -f '/usr/lib64/libz.so'},
change to:    'glibc-devel'    => sub { -f '/usr/lib/libm.so' || -f '/usr/lib64/libz.so' || -f '/usr/lib/x86_64-linux-gnu/libm.so'},

Line 585:                                    glob('/lib64/libz.so*')  ); @f > 1 ? 1 : 0 },
change to:                                   glob('/lib64/libz.so*'), glob('/usr/lib/x86_64-linux-gnu/libz.so*'), glob('/lib/x86_64-linux-gnu/libz.so*')); @f > 1 ? 1 : 0 },
</code></WRAP>

A graphical menu to select the platform appears after a while. Select ''Platform choice'' and press Enter.

{{:ltib-platform-selection1.png?600|}}

Select ''TQ-Components iMX boards'' in this window and press Enter

{{:ltib-platform-selection2.png?600|}}

Then select ''< Exit >''. Different profiles for the rootfs can be selected in the next window.

{{:ltib-package-profile.png?600|}}

We first use the Min profile. All options are shown again in the next window. Nothing has to be changed there. The wizzard is closed with ''< Exit >'' and the selected operations are performed.

The success message at the end should look like this:
<code bash>

===== NFS =====
The following line has to be added to ''/etc/exports'' to access the rootfs via NFS. Also see [[en:nfs|Installation from NFS server]]
<code>/opt/ltib_iMX35/ltib/rootfs 192.168.30.0/24(rw,no_root_squash,sync)
