Disclaimer

Cutter is not aimed at existing radare2 users. It instead focuses on those whose are not yet radare2 users because of the learning curve, because they don't like CLI applications or because of the difficulty/instability of radare2.

Installing

Downloading a release

Cutter is available for all platforms (Linux, OS X, Windows). You can download the latest release here.

  • Linux: use the AppImage file. Then just make it executable and run it:
    • chmod +x Cutter-v1.7.1-x86_64.AppImage
    • ./Cutter-v1.7.1-x86_64.AppImage

Building from source

Requirements

Cutter is based on Qt so you will need to have it installed.

Building

First you must clone the repository:

git clone --recurse-submodules https://github.com/radareorg/cutter
cd cutter

Building on linux:

./build.sh
Important note:

When using the default build.sh script you might encounter a ModuleNotFoundError upon starting Cutter. This can be resolved by either

  1. disabling the optional jupyter support during building by modifying build.sh as follows:

    • Uncomment #QMAKE_CONF="CUTTER_ENABLE_JUPYTER=false CUTTER_ENABLE_QTWEBENGINE=false"
    • Comment out the prior empty QMAKE_CONF=""
  2. or alternatively by installing the two python dependencies manually afterwards via:

pip3 install notebook jupyter_client

Building on Windows:

prepare_r2.bat
build.bat

If any of those do not work, check the more detailed version here.
