+
+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 2.95 or any later)
+** `g++` (version 2.95 or any later)
+** +bash+
+** +patch+
+** +gzip+
+** +bzip2+
+** +perl+ (version 5.8.7 or any later)
+** +tar+
+** +cpio+
+** +python+ (version 2.6 or 2.7)
+** +unzip+
+** +rsync+
+
+* Source fetching tools:
+** +wget+
+
+[[requirement-optional]]
+
+=== Optional packages
+
+* 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'
