Building
========

First you must get the source of Cutter by cloning the repository:

::

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

The “official” way to build Cutter is by using qmake, but there are two
alternatives – cmake and meson.

In any case, there are obviously some requirements:

* Radare2 installed from submodule
* Qt 5.9 or above
* Python3.6
* Breakpad installed using script (optional, disabled by default)

Before compiling, note that we also provide binaries available for
windows/linux/MacOS `here <https://github.com/radareorg/cutter/releases>`_.

--------------

Building options
----------------

Note that there are three major building options available:

* ``CUTTER_ENABLE_PYTHON`` compile with Python support
* ``CUTTER_ENABLE_PYTHON_BINDINGS`` automatically generate Python Bindings with Shiboken2, required for Python plugins!
* ``CUTTER_ENABLE_CRASH_REPORTS`` is used to compile Cutter with crash handling system enabled (Breakpad)

--------------

Preparing Breakpad
-------------------

If you want to build Cutter with crash handling system, you want prepare Breakpad before.
For this simply run one of the scripts (according to your OS) from root Cutter directory:
    
.. code:: sh

   source scripts/prepare_breakpad_linux.sh # Linux
   source scripts/prepare_breakpad_macos.sh # MacOS
   scripts/prepare_breakpad.bat # Windows
   
Then if you are building on Linux you want to change ``PKG_CONFIG_PATH`` environment variable
so it contains ``$CUSTOM_BREAKPAD_PREFIX/lib/pkgconfig``. For this simply run

.. code:: sh

   export PKG_CONFIG_PATH="$CUSTOM_BREAKPAD_PREFIX/lib/pkgconfig:$PKG_CONFIG_PATH"


--------------

Building with Qmake
-------------------

Compiling on Linux / macOS
^^^^^^^^^^^^^^^^^^^^^^^^^^

The easy way is to simply run ``./build.sh`` from the root directory,
and let the magic happen. The script will use qmake to build Cutter.

If you want to manually use qmake, follow this steps:

.. code:: sh

   mkdir build; cd build
   qmake ../src/Cutter.pro
   make
   cd ..

Additional steps for macOS
^^^^^^^^^^^^^^^^^^^^^^^^^^

On macOS you will also have to copy the launcher bash script:

.. code:: sh

   mv Cutter.app/Contents/MacOS/Cutter Cutter.app/Contents/MacOS/Cutter.bin
   cp ../src/macos/Cutter Cutter.app/Contents/MacOS/Cutter && chmod +x Cutter.app/Contents/MacOS/Cutter

--------------

Building with Cmake
-------------------

Requirements
~~~~~~~~~~~~

-  CMake >= 3.1

Building on Linux
~~~~~~~~~~~~~~~~~

The root for CMake is in src/. In-source builds are **not allowed**, so
you **must** run CMake from a separate directory:

.. code:: sh

   cd src
   mkdir build
   cd build
   cmake .. # Don't forget to provide build options

If all went well, you should now have a working Makefile in your build
directory:

::

   make

--------------

Building on Windows
-------------------

Alternatively, on Windows you can run something like this (depending on
your Cmake installation)

.. code:: batch

   set CMAKE_PREFIX_PATH=c:\Qt\qt-5.6.2-msvc2013-x86\5.6\msvc2013\lib\cmake
   cd src
   mkdir build
   cd build
   cmake-gui ..

Click ``Configure`` and select ``Visual Studio 14 2015`` from the list.
After configuration is done, click ``Generate`` and you can open
``Cutter.sln`` to compile the code as usual.

Troubleshooting
---------------

   Cmake: qt development package not found

Depending on how Qt installed (Distribution packages or using the Qt
installer application), CMake may not be able to find it by itself if it
is not in a common place. If that is the case, double check that the
correct Qt version is installed. Locate its prefix (a directory
containing bin/, lib/, include/, etc.) and specify it to CMake using
``CMAKE_PREFIX_PATH`` in the above process, e.g.:

::

   rm CMakeCache.txt # the cache may be polluted with unwanted libraries found before
   cmake -DCMAKE_PREFIX_PATH=/opt/Qt/5.9.1/gcc_64 ..

Building with Meson (Windows)
-----------------------------

Additional requirements:

-  Visual Studio 2015 or Visual Studio 2017
-  Ninja build system
-  Meson build system

Download and unpack
`Ninja <https://github.com/ninja-build/ninja/releases>`__ to the Cutter
source root directory.

Environment settings (example for x64 version):

.. code:: batch

    :: Export MSVC variables
    CALL "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" x64
    :: Add qmake to PATH
    SET "PATH=C:\Qt\5.10.1\msvc2015_64\bin;%PATH%"
    :: Add Python to PATH
    SET "PATH=C:\Program Files\Python36;%PATH%"

Install Meson:

.. code:: batch

   python -m pip install meson

To compile Cutter run:

.. code:: batch

   CALL prepare_r2.bat
   CALL build.bat
