r2 is a rewrite from scratch of radare in order to provide a set of libraries and tools to work with binary files.

Radare project started as a forensics tool, a scriptable command-line hexadecimal editor able to open disk files, but later added support for analyzing binaries, disassembling code, debugging programs, attaching to remote gdb servers...

To learn more you may read the official radare2 book, the source code, or browse the web for blog posts or presentations from r2con.

The recommended way to install or update radare2 from git for single-user systems:

$ sys/install.sh

If you don't have root, or just want to install it in your home use:

$ sys/user.sh

Note that those scripts will install using configure+make using symlinks, so you don't need to reinstall every time you change something in the builddir.

• If you don't like symlinks use sys/install.sh --install
• To use capstone5 use the --with-capstone5 flag.

Alternatively you can also build with meson + ninja:

$ sys/meson.py --prefix=/usr --shared --install

Or install in your home with meson + ninja:

$ sys/meson.py --prefix=$HOME/r2meson --local --shared --install

In case of a polluted filesystem, you can uninstall the current version or remove all previous installations:

$ make uninstall
$ make purge

To remove all stuff including libraries, use

$ make system-purge

Radare2 has its own package manager - r2pm. Its packages repository is on GitHub too. To start to using it for the first time, you need to initialize packages:

$ r2pm init

Refresh the packages database before installing any package:

$ r2pm update

To install a package, use the following command:

$ r2pm install [package name]

Look at CONTRIBUTING.md.

Running make tests will fetch the test binaries repository and run all the tests in order to verify that no changes break any functionality.

We run those tests on every commit, and they are also executed with ASAN and valgrind on different platforms to catch other unwanted 'features'.
