Currently, we only require a gcc 4.4 version, which now is pretty old (released in April 2009). This requirement is not even tested nowadays, with our oldest autobuilder having a 4.7 version only. And even then, 4.7 is still old enough that it prevents us from upgrading some packages. For example cmake 3.10+ requires C++11 constructs that were only added in gcc 4.8 (when C++11 support was finally completed in gcc). So, update our requirements for gcc to at least 4.8.

== System requirements
|
|
|
|
Buildroot is designed to run on Linux systems.
|
|
|
|
While Buildroot itself will build most host packages it needs for the
|
|
compilation, certain standard Linux utilities are expected to be
|
|
already installed on the host system. Below you will find an overview of
|
|
the mandatory and optional packages (note that package names may vary
|
|
between distributions).
|
|
|
|
[[requirement-mandatory]]
|
|
|
|
=== Mandatory packages
|
|
|
|
* Build tools:
|
|
|
|
** +which+
|
|
** +sed+
|
|
** +make+ (version 3.81 or any later)
|
|
** +binutils+
|
|
** +build-essential+ (only for Debian based systems)
|
|
** +gcc+ (version 4.8 or any later)
|
|
** `g++` (version 4.8 or any later)
|
|
** +bash+
|
|
** +patch+
|
|
** +gzip+
|
|
** +bzip2+
|
|
** +perl+ (version 5.8.7 or any later)
|
|
** +tar+
|
|
** +cpio+
|
|
** +unzip+
|
|
** +rsync+
|
|
** +file+ (must be in +/usr/bin/file+)
|
|
** +bc+
|
|
|
|
* Source fetching tools:
|
|
** +wget+
|
|
|
|
[[requirement-optional]]
|
|
|
|
=== Optional packages
|
|
|
|
* Recommended dependencies:
|
|
+
|
|
Some features or utilities in Buildroot, like the legal-info, or the
|
|
graph generation tools, have additional dependencies. Although they
|
|
are not mandatory for a simple build, they are still highly recommended:
|
|
+
|
|
** +python+ (version 2.7 or any later)
|
|
|
|
* Configuration interface dependencies:
|
|
+
|
|
For these libraries, you need to install both runtime and development
|
|
data, which in many distributions are packaged separately. The
|
|
development packages typically have a _-dev_ or _-devel_ suffix.
|
|
+
|
|
** +ncurses5+ to use the 'menuconfig' interface
|
|
** +qt4+ to use the 'xconfig' interface
|
|
** +glib2+, +gtk2+ and +glade2+ to use the 'gconfig' interface
|
|
|
|
* Source fetching tools:
|
|
+
|
|
In the official tree, most of the package sources are retrieved using
|
|
+wget+ from _ftp_, _http_ or _https_ locations. A few packages are only
|
|
available through a version control system. Moreover, Buildroot is
|
|
capable of downloading sources via other tools, like +rsync+ or +scp+
|
|
(refer to xref:download-infra[] for more details). If you enable
|
|
packages using any of these methods, you will need to install the
|
|
corresponding tool on the host system:
|
|
+
|
|
** +bazaar+
|
|
** +cvs+
|
|
** +git+
|
|
** +mercurial+
|
|
** +rsync+
|
|
** +scp+
|
|
** +subversion+
|
|
|
|
* Java-related packages, if the Java Classpath needs to be built for
|
|
the target system:
|
|
** The +javac+ compiler
|
|
** The +jar+ tool
|
|
|
|
* Documentation generation tools:
|
|
** +asciidoc+, version 8.6.3 or higher
|
|
** +w3m+
|
|
** +python+ with the +argparse+ module (automatically present in 2.7+ and 3.2+)
|
|
** +dblatex+ (required for the pdf manual only)
|
|
|
|
* Graph generation tools:
|
|
** +graphviz+ to use 'graph-depends' and '<pkg>-graph-depends'
|
|
** +python-matplotlib+ to use 'graph-build'
