Ubuntu/Debian installation prerequisites

Mandatory packages

• you can use the following commands (one at a time) to get them (assuming your userid is allowed to use sudo (execution of commands as root)):

 sudo apt-get install -y build-essential gcc g++ autoconf automake libtool bison flex gettext 
 sudo apt-get install -y patch subversion texinfo wget git-core
 sudo apt-get install -y libncurses5 libncurses5-dev
 sudo apt-get install -y zlib1g-dev liblzo2-2 liblzo2-dev
 sudo apt-get install -y libacl1 libacl1-dev gawk cvs curl lzma 
 sudo apt-get install -y uuid-dev mercurial

Warning: For recent Ubuntu and Debian based systems, the following is now required if your /bin/sh is not pointing to /bin/bash: $ ls -al /bin/sh lrwxrwxrwx 1 root root 4 2007-12-08 18:33 /bin/sh -> dash $ sudo dpkg-reconfigure dash and select no Indeed dash do not support all the capabilities needed by Buildroot (our build system).

• if your distribution is localized in a language different of English, you will need to install "en_US" locale in order to compile the toolchain (by default our toolchain (uClibc) is configured to only support English). If not, you will get compilation errors like this one:

 ...
 extra/locale/locale_mmap.h:46: error: '__LOCALE_DATA_WCctype_II_LEN' undeclared here (not in a function)
 ...

To solve this, install en_US.UTF-8 locale with the following:

 $ sudo dpkg-reconfigure locales

Optional packages

Not mandatory but useful to add for compiling some Buildroot packages:

 sudo apt-get -y install libglib2.0-dev
 sudo apt-get -y install libnetpbm10-dev   (for fbtest)
 sudo apt-get -y install python-xcbgen (for Matchbox)
