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.
7. Log out of your Windows session.
8. Open up a new Windows Command Prompt: type cmd in the search bar. Ensure that the current path is not in the Radare2 folder.
9. Check Radare2 version from Command Prompt Window: radare2 -v
Radare2 can be cross-compiled for other architectures/systems as well, like Android.
• Python 3
• Meson
• Ninja
• Git
• Android NDK
Download the Android NDK from the official site and extract it somewhere on your system (e.g. /tmp/android-ndk)
$ echo NDK=/tmp/android-ndk > ~/.r2androidrc
./sys/android-build.sh arm64-static
You can build for different architectures by changing the argument to ./sys/android-build.sh. Run the script without any argument to see the accepted values.
Meson needs a configuration file that describes the cross compilation environment (e.g. meson-android.ini). You can adjust it as necessary, but something like the following should be a good starting point:
[binaries]
c = '/tmp/android-ndk/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android28-clang'
cpp = '/tmp/android-ndk/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android28-clang++'
ar = '/tmp/android-ndk/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android-ar'
as = '/tmp/android-ndk/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android-as'
ranlib = '/tmp/android-ndk/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android-ranlib'
ld = '/tmp/android-ndk/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android-ld'
strip = '/tmp/android-ndk/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android-strip'
pkgconfig = 'false'
[properties]
sys_root = '/tmp/android-ndk/sysroot'
[host_machine]
system = 'android'
cpu_family = 'arm'
cpu = 'aarch64'
endian = 'little'
Now setup the build directory with meson as usuaclass="underline"
