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 unzip
 sudo apt-get install -y libftdi-dev
 sudo apt-get install -y bc quilt
 
 # for Linaro external toolchain of APF6 on 64bits Host:
 sudo apt-get install -y lib32stdc++6 lib32z1
 
 # to use recover tool if board is bricked:
 #            python 2 :                                               /                 python 3 :
 sudo apt-get install -y python-serial python-usb libusb-1.0-0-dev     /    sudo apt-get install -y python3-serial python3-usb libusb-dev

• you will need bash as system interpreter and NOT dash:

$ sudo dpkg-reconfigure dash      (choose No)

Localization

• 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

64 bits Hosts

• On Debian/Jessie, these packages seems to be required (on 64 bits Host):

sudo apt-get install libx32stdc++6 libx32stdc++-4.9-dev lib64stdc++6

• On Debian 9 the following seems also recommended:

 sudo apt-get install libssl1.0-dev

On LUbuntu 16.04 it is:

 sudo apt-get install libssl-dev

otherwise you will get:

scripts/extract-cert.c:21:25: fatal error: openssl/bio.h: No such file or directory
compilation terminated.
scripts/Makefile.host:90: recipe for target 'scripts/extract-cert' failed

• On *Ubuntu 16.04, the following is required:

sudo apt-get install gcc-multilib

otherwise you may get:

In file included from ../../../libgcc/libgcc2.c:27:0:
../../../libgcc/../gcc/tsystem.h:87:19: fatal error: stdio.h: No such file or directory
 #include <stdio.h>
                   ^
compilation terminated.

Optional packages

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

 sudo apt-get -y install libglib2.0-dev 
 # for fbtest
 sudo apt-get -y install libnetpbm10-dev
 # for Matchbox
 sudo apt-get -y install python-xcbgen
 # for mesa
 sudo apt-get -y install xutils-dev
 # for imx_usb
 sudo apt-get -y install pkg-config

Java devt

Ubuntu To compile java jamvm and gnu-classpath: sudo apt-get -y install gcj-jdk
