Rizin can be cross-compiled for other architectures/systems as well, like Android.
- Python 3
- Android NDK
Download the Android NDK from the official site and extract it somewhere on your system (e.g.
See also BUILDING.md.
Meson needs a configuration file that describes the cross compilation environment (e.g.
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 usual:
$ meson --default-library static -Dstatic_runtime=true --prefix=/tmp/android-dir -Dblob=true build --cross-file ./meson-android.ini
A bit of explanation about all the options:
--default-library static -Dstatic_runtime=true: this ensure that libraries and binaries are statically compiled, so you do not need to properly set LD_* environment variables in your Android environment to make it find the right libraries. Binaries have everything they need inside.
-Dblob=true: it tells meson to compile just one binary with all the needed code for running
rz-asm, etc. and creates symbolic links to those names. This avoids creating many statically compiled large binaries and just create one that provides all features. You will still have
rz-ax, etc. but they are just symlinks to
--cross-file ./meson-android.ini: it describes how to compile rizin for Android
Then compile and install the project:
$ ninja -C build $ ninja -C build install
At this point you can copy the generated files in /tmp/android-dir to your Android device and running rizin from it. For example:
$ cd /tmp && tar -cvf rizin-android.tar.gz android-dir $ adb push rizin-android.tar.gz /data/local/tmp $ adb shell DEVICE:/ $ cd /data/local/tmp DEVICE:/data/local/tmp $ tar xvf rizin-android.tar.gz DEVICE:/data/local/tmp $ ./android-dir/bin/rizin Usage: rizin [-ACdfLMnNqStuvwzX] [-P patch] [-p prj] [-a arch] [-b bits] [-i file] [-s addr] [-B baddr] [-m maddr] [-c cmd] [-e k=v] file|pid|-|--|=
