• Visual Studio 2015 (or higher)
• Python 3
• Meson
• Git
Visual Studio must be installed with a Visual C++ compiler, supporting C++ libraries, and the appropriate Windows SDK for the target platform version.
• In the Visual Studio 2015 installer, ensure Programming Languages > Visual C++ is selected
• In the Visual Studio 2017+ installers, ensure the Desktop development with C++ workload is selected
If you need a copy of Visual Studio, the Community versions are free and work great.
• Download Visual Studio 2015 Community (registration required)
• Download Visual Studio 2017 Community
It is strongly recommended you install Conda — a Python environment management system — when working with Python on the Windows platform. This will isolate the Radare2 build environment from other installed Python versions and minimize potential conflicts.
1. Download the appropriate Conda (Python 3.x) for your platform (https://conda.io/miniconda.html)
2. Install Conda with the recommended defaults
Follow these steps to create and activate a Conda environment named r2. All instructions from this point on will assume this name matches your environment, but you may change this if desired.
1. Start > Anaconda Prompt
2. conda create -n r2 python=3
3. activate r2
Any time you wish to enter this environment, open the Anaconda Prompt and re-issue activate r2. Conversely, deactivate will leave the environment.
1. Enter the Radare2 Conda environment, if needed (activate r2)
2. Download https://github.com/mesonbuild/meson/archive/master.zip
3. pip install \path\to\downloaded\master.zip
4. Verify Meson is version 0.48 or higher (meson -v)
All Radare2 code is managed via the Git version control system and hosted on GitHub.
Follow these steps to install Git for Windows.
1. Download Git for Windows (https://git-scm.com/download/win)
As you navigate the install wizard, we recommend you set these options when they appear: * Use a TrueType font in all console windows * Use Git from the Windows Command Prompt * Use the native Windows Secure Channel library (instead of OpenSSL) * Checkout Windows-style, commit Unix-style line endings (core.autocrlf=true) * Use Windows' default console window (instead of Mintty)
2. Close any previously open console windows and re-open them to ensure they receive the new PATH
3. Ensure git --version works
Follow these steps to clone the Radare2 git repository.
1. In your Radare2 Conda environment, navigate to a location where the code will be saved and compiled. This location needs approximately 3-4GiB of space
2. Clone the repository with git clone https://github.com/radareorg/radare2.git
Follow these steps to compile the Radare2 Code.
Compiled binaries will be installed into the dest folder.
1. Enter the Radare2 Conda environment
2. Navigate to the root of the Radare2 sources (cd radare2)
3. Initialize Visual Studio tooling by executing the command below that matches the version of Visual Studio installed on your machine and the version of Radare2 you wish to instalclass="underline"
Visual Studio 2015:
Note: For the 64-bit version change only the x86 at the very end of the command below to x64.
"%ProgramFiles(x86)%\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" x86
Visual Studio 2017:
Note 1: Change Community to either Professional or Enterprise in the command below depending on the version installed.
Note 2: Change vcvars32.bat to vcvars64.bat in the command below for the 64-bit version.
"%ProgramFiles(x86)%\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\vcvars32.bat"
Visual Studio Preview:
Note 1: Change Community to either Professional or Enterprise in the command below depending on the version installed.
Note 2: Change vcvars32.bat to vcvars64.bat in the command below for the 64-bit version.
"%ProgramFiles(x86)%\Microsoft Visual Studio\Preview\Community\VC\Auxiliary\Build\vcvars32.bat"
4. Generate the build system with Meson:
Note 1: Change debug to release in the command below depending on whether the latest version or release version is desired.
Note 2: If you are using visual studio 2017, you can change swap vs2015 for vs2017.
meson build --buildtype debug --backend vs2015 --prefix %cd%\dest
Meson currently requires --prefix to point to an absolute path. We use the %CD% pseudo-variable to get the absolute path to the current working directory.
5. Start a build:
Note: Change Debug to Release in the command below depending on the version desired.
msbuild build\radare2.sln /p:Configuration=Debug /m
The /m[axcpucount] switch creates one MSBuild worker process per logical processor on your machine. You can specify a numeric value (e.g. /m:2) to limit the number of worker processes if needed. (This should not be confused with the Visual C++ Compiler switch /MP.)
If you get an error with the 32-bit install that says something along the lines of error MSB4126: The specified solution configuration "Debug|x86" is invalid. Get around this by adding the following argument to the command: /p:Platform=Win32
6. Install into your destination folder: meson install -C build --no-rebuild
7. Check your Radare2 version: dest\bin\radare2.exe -v
1. In the file explorer go to the folder Radare2 was just installed in.
2. From this folder go to dest > bin and keep this window open.
3. Go to System Properties: In the Windows search bar enter sysdm.cpl.
4. Go to Advanced > Environment Variables.
5. Click on the PATH variable and then click edit (if it exists within both the user and system variables, look at the user version).
6. Ensure the file path displayed in the window left open is listed within the PATH variable. If it is not add it and click ok.
