# RetDec IDA plugin



RetDec plugin for IDA (Interactive Disassembler).



The plugin is compatible with the IDA 7.5+ versions.

The plugin does NOT work with IDA 6.x, IDA 7.0-7.4, or freeware version of IDA 7.0.

The plugin comes at both 32-bit and 64-bit address space variants (both are 64-bit binaries). I.e. it works in both `ida` and `ida64`.

At the moment, it can decompile the following architectures:

* 32-bit: x86, arm, mips, and powerpc.

* 64-bit: x86-64, arm64.



## Installation and Use



Currently, we officially support only Windows and Linux. It may be possible to build macOS version from the sources, but since we do not own a macOS version of IDA, we cannot create a pre-built package, or continually make sure the macOS build is not broken.



1. Either download and unpack a pre-built package from the [latest release](https://github.com/avast/retdec-idaplugin/releases/latest), or build and install the RetDec IDA plugin by yourself (the process is described below).

2. Follow the user guide (`user_guide.pdf`) that is part of the downloaded package, or use the [current version](https://github.com/avast/retdec-idaplugin/blob/master/doc/user_guide/user_guide.pdf) from this repository.

3. Don't forget to install the required dependencies mentioned in the user guide.



## Build and Installation



### Requirements



**Note: These are requirements to build the RetDec IDA plugin, not to run it. See our [User Guide](https://github.com/avast/retdec-idaplugin/blob/master/doc/user_guide/user_guide.pdf) for information on plugin installation, configuration, and use.**



* A compiler supporting C++17

  * On Windows, only Microsoft Visual C++ is supported (version >= Visual Studio 2017).

* CMake (version >= 3.6)

* IDA SDK (version >= 7.7)



### Process



* Clone the repository:

  * `git clone https://github.com/avast/retdec-idaplugin.git`

* Linux:

  * `cd retdec-idaplugin`

  * `mkdir build && cd build`

  * `cmake .. -DIDA_SDK_DIR=`

  * `make`

  * `make install` (if `IDA_DIR` was set, see below)

* Windows:

  * Open a command prompt (e.g. `C:\msys64\msys2_shell.cmd` from [MSYS2](https://github.com/avast/retdec/wiki/Windows-Environment))

  * `cd retdec-idaplugin`

  * `mkdir build && cd build`

  * `cmake .. -DIDA_SDK_DIR= -G`

  * `cmake --build . --config Release -- -m`

  * `cmake --build . --config Release --target install` (if `IDA_DIR` was set, see below)

  * Alternatively, you can open `retdec-idaplugin.sln` generated by `cmake` in Visual Studio IDE.



You must pass the following parameters to `cmake`:

* `-DIDA_SDK_DIR=` to tell `cmake` where the IDA SDK directory is located.

* (Windows only) `-G` is `-G"Visual Studio 15 2017 Win64"` for 64-bit build using Visual Studio 2017. Later versions of Visual Studio may be used. Only 64-bit build is supported.



You can pass the following additional parameters to `cmake`:

* `-DIDA_DIR=` to tell `cmake` where to install the plugin. If specified, installation will copy plugin binaries into `IDA_DIR/plugins`, and content of `scripts/idc` directory into `IDA_DIR/idc`. If not set, installation step does nothing.

* `-DRETDEC_IDAPLUGIN_DOC=ON` to enable the `user-guide` target which generates the user guide document (disabled by default, the target needs to be explicitly invoked).



## User Guide



The [User Guide](https://github.com/avast/retdec-idaplugin/blob/master/doc/user_guide/user_guide.pdf) in a PDF form is located in `doc/user_guide/user_guide.pdf`.



You can build your own guide by enabling and invoking the `user-guide` target:

* `cmake .. -DRETDEC_IDAPLUGIN_DOC=ON`

* Linux: `make user-guide`

* Windows: `cmake --build . --config Release --target user-guide`

* Requires [LaTeX](https://www.latex-project.org/), LaTeX packages, and related tools.

* The resulting PDF will overwrite the original `user_guide.pdf` in `doc/user_guide`.
