This documentation explains how to build & install Keystone on all kind of nix OS. For Windows, see COMPILE-WINDOWS.md

  1. Dependency

CMake is required to build keystone.

  • On Mac OS X, you can install "cmake" with "brew".

    $ brew install cmake
    
  • On Ubuntu Linux, install "cmake" with:

    $ sudo apt-get install cmake
    
  1. From the root directory of Keystone source, compile its dynamic library with the following commands.

     $ mkdir build
     $ cd build
     $ ../make-share.sh
    

    In the case you want to compile with all the debug information, replace the last line with:

     $ ../make-share.sh debug
    

    For Linux distributions following the "Filesystem Hierarchy Standard" and put x64 libraries under $PREFIX/lib64, such as Fedora, Redhat & Suse, add "lib64" option at the end of make-share.sh script, like below.

     $ ../make-share.sh lib64
    

    By default, this builds all architectures, which is: AArch64, ARM, Hexagon, Mips, PowerPC, Sparc, SystemZ & X86. To compile just some selected ones, pass a semicolon-separated list of targets to LLVM_TARGETS_TO_BUILD, like follows if we only want AArch64 & X86.

     $ cmake -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=ON -DLLVM_TARGETS_TO_BUILD="AArch64;X86" -G "Unix Makefiles" ..
     $ make -j8
    

    You can also compile static a library with:

     $ mkdir build
     $ cd build
     $ ../make-lib.sh
    

    In the case you want to compile with all the debug information, replace the last line with:

     $ ../make-lib.sh debug
    

    For Linux distributions following the "Filesystem Hierarchy Standard" and put x64 libraries under $PREFIX/lib64, such as Fedora, Redhat & Suse, add "lib64" option at the end of make-share.sh script, like below.

     $ ../make-lib.sh lib64
    

    Like above, this builds all architectures. To compile just some selected ones, pass a semicolon-separated list of targets to LLVM_TARGETS_TO_BUILD, like follows if we only want AArch64 & X86.

     $ cmake -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=OFF -DLLVM_TARGETS_TO_BUILD="AArch64, X86" -G "Unix Makefiles" ..
     $ make -j8
    

    To customize your build by specifying PREFIX or other installation directories, pass one of the variables at https://cmake.org/cmake/help/v3.0/module/GNUInstallDirs.html to cmake. For example:

     $ cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=OFF -DLLVM_TARGETS_TO_BUILD="AArch64, X86" -G "Unix Makefiles" ..
     $ make -j8
    
  2. Right after building, install Keystone.

     $ sudo make install
    

    Keystone is installed in /usr/local, depending on your distribution (eg. Ubuntu) you might need to add /usr/local/lib to /etc/ld.so.conf. Then update the dynamic linker with:

     $ sudo ldconfig
    

    Besides the libraries & C header files under directory "include/keystone", this step also installs a tool named "kstool" on the system. (The source of "kstool" is in the directory "kstool/kstool")

  3. Test Keystone with "kstool" like below.

     $ kstool x32 "add eax, ebx"
    

    Run "kstool" without any option to find out how to use this handy tool.
