This HOWTO introduces how to build Unicorn2 natively on Linux/Mac/Windows or cross-build to Windows from Linux host.
|
|
|
|
Note: Please run `make clean` before you switch to `dev` branch.
|
|
|
|
## Native build on Linux/macOS
|
|
|
|
This builds Unicorn2 on Linux/macOS. Note that this also applies to Apple Silicon M1 users.
|
|
|
|
- Install `cmake` and `pkg-config` with your favorite package manager:
|
|
|
|
Ubuntu:
|
|
|
|
``` bash
|
|
sudo apt install cmake pkg-config
|
|
```
|
|
|
|
macOS:
|
|
|
|
```bash
|
|
brew install cmake pkg-config
|
|
```
|
|
|
|
- Build with the following commands.
|
|
|
|
```bash
|
|
mkdir build; cd build
|
|
cmake .. -DCMAKE_BUILD_TYPE=Release
|
|
make
|
|
```
|
|
|
|
## Native build on Windows, with MSVC
|
|
|
|
This builds Unicorn2 on Windows, using Microsoft MSVC compiler.
|
|
|
|
- Require `cmake` & `Microsoft Visual Studio`.
|
|
|
|
- From Visual Studio Command Prompt, build with the following commands.
|
|
|
|
```bash
|
|
mkdir build; cd build
|
|
cmake .. -G "NMake Makefiles" -DCMAKE_BUILD_TYPE=Release
|
|
nmake
|
|
```
|
|
|
|
Note, other generators like `Ninja` and `Visual Studio 16 2019` would also work.
|
|
|
|
```bash
|
|
mkdir build; cd build
|
|
cmake .. -G "Visual Studio 16 2019" -A "win32" -DCMAKE_BUILD_TYPE=Release
|
|
msbuild unicorn.sln -p:Plaform=Win32 -p:Configuration=Release
|
|
```
|
|
|
|
## Cross build with NDK
|
|
|
|
To build Unicorn2 on the Android platform, firstly you need to download [NDK](https://developer.android.com/ndk/downloads).
|
|
|
|
For newer NDK, please make sure your cmake version is above 3.19.
|
|
|
|
Then generate the project like:
|
|
|
|
```bash
|
|
mkdir build; cd build;
|
|
cmake .. -DCMAKE_TOOLCHAIN_FILE=$NDK/build/cmake/android.toolchain.cmake -DANDROID_ABI=$ABI -DANDROID_NATIVE_API_LEVEL=$MINSDKVERSION
|
|
make
|
|
```
|
|
|
|
You may get the possible values from this [page](https://developer.android.com/ndk/guides/cmake).
|
|
|
|
Unicorn2 support cross-build for `armeabi-v7a`, `arm64-v8a`, `x86` and `x86_64`.
|
|
|
|
Note the build is only tested and guaranteed to work under Linux, however, other systems may still work.
|
|
|
|
## Cross build from Linux host to Windows, with Mingw
|
|
|
|
This cross-builds Unicorn2 from **Linux host** to Windows, using `Mingw` compiler.
|
|
|
|
- Install required package.
|
|
|
|
```bash
|
|
sudo apt install mingw-w64-x86-64-dev
|
|
```
|
|
|
|
- Build Unicorn and samples with the following commands.
|
|
|
|
```bash
|
|
mkdir build; cd build
|
|
cmake .. -DCMAKE_TOOLCHAIN_FILE=../mingw64-w64.cmake
|
|
make
|
|
```
|
|
|
|
## Native build on Windows host, with MSYS2/Mingw
|
|
|
|
This builds Unicorn2 on **Windows host**, using **MSYS2/Mingw** compiler.
|
|
|
|
This requires MSYS2 to be installed on the Windows machine. You need to download & install MSYS2 from https://www.msys2.org.
|
|
|
|
Then from MSYS2 console, install packages below:
|
|
|
|
```bash
|
|
pacman -S mingw-w64-x86_64-toolchain mingw-w64-x86_64-cmake
|
|
```
|
|
|
|
- Build Unicorn and samples with the following commands.
|
|
|
|
```bash
|
|
mkdir build; cd build
|
|
/mingw64/bin/cmake .. -G "MSYS Makefiles" -DCMAKE_C_COMPILER=/mingw64/bin/gcc.exe -DCMAKE_MAKE_PROGRAM=/mingw64/bin/mingw32-make.exe -DCMAKE_AR=/mingw64/bin/ar.exe -DUNICORN_ARCH=x86
|
|
mingw32-make
|
|
```
|
|
|
|
Note that the way to build on MSYS changes as time goes, please keep in mind that always use the cmake shipped with mingw64 and choose MSYS Makefiles.
|
|
|
|
## Cross build from Linux host to other architectures
|
|
|
|
This cross-builds Unicorn2 from **Linux host** to other architectures, using a cross compiler.
|
|
|
|
- Install cross compiler package. For example, cross-compile to ARM requires the below command.
|
|
|
|
```bash
|
|
sudo apt install gcc-arm-linux-gnueabihf
|
|
```
|
|
|
|
- Build Unicorn and samples with the following commands. The compiler name differs according to your targets.
|
|
|
|
```bash
|
|
mkdir build; cd build
|
|
cmake .. -DCMAKE_C_COMPILER=gcc-arm-linux-gnueabihf
|
|
make
|
|
```
