This documentation explains how to compile, install & run Unicorn on MacOSX,
Linux, *BSD & Solaris. We also show steps to cross-compile for Microsoft Windows.

                        *-*-*-*-*-*

[0] Dependencies

Unicorn requires few dependent packages as followings

- For Mac OS X, "pkg-config" is needed.
  Brew users can install "pkg-config" with:

      $ brew install pkg-config

- For Linux, glib2-dev is needed.
  Ubuntu/Debian users can install this with:

      $ sudo apt-get install libglib2.0-dev

- For Windows, cross-compile using Mingw. Mingw-glib2 is needed.

    On Ubuntu 14.04 64-bit, do:

        1. Download DEB packages for Mingw64 from https://launchpad.net/~greg-hellings/+archive/ubuntu/mingw-libs/+build/2924251

        2. To cross-compile for Windows 32-bit, install Mingw with (ignore all the warnings):

            $ sudo dpkg -i --force-depends mingw64-x86-glib2_2.31.0_all.deb

           To cross-compile for Windows 64-bit, install Mingw with:

            $ sudo dpkg -i --force-depends mingw64-x64-glib2_2.31.0_all.deb



[1] Tailor Unicorn to your need.

  Out of 8 archtitectures supported by Unicorn (Arm, Arm64, Mips, PPC, Sparc,
  SystemZ, XCore & X86), if you just need several selected archs, choose which
  ones you want to compile in by editing "config.mk" before going to next steps.

  By default, all 8 architectures are compiled.

  The other way of customize Unicorn without having to edit config.mk is to
  pass the desired options on the commandline to ./make.sh. Currently,
  Unicorn supports 3 options, as followings.

  - UNICORN_ARCHS: specify list of architectures to compiled in.
  - UNICORN_STATIC: build static library.
  - UNICORN_SHARED: build dynamic (shared) library.

  To avoid editing config.mk for these customization, we can pass their values to
  make.sh, as followings.

  $ UNICORN_ARCHS="arm aarch64 x86" ./make.sh

  NOTE: on commandline, put these values in front of ./make.sh, not after it.

  For each option, refer to docs/README for more details.



[2] Compile from source

  On *nix (such as MacOSX, Linux, *BSD, Solaris):

  - To compile for current platform, run:

		$ ./make.sh

  - On 64-bit OS, run the command below to cross-compile Unicorn for 32-bit binary:

		$ ./make.sh nix32



[3] Install Unicorn on *nix (such as MacOSX, Linux, *BSD, Solaris)

  To install Unicorn, run:

	$ sudo ./make.sh install

	For FreeBSD/OpenBSD, where sudo is unavailable, run:

		$ su; ./make.sh install

  Users are then required to enter root password to copy Unicorn into machine
  system directories.

  Afterwards, run ./tests/test* to see the tests disassembling sample code.


  NOTE: The core framework installed by "./make.sh install" consist of
  following files:

	/usr/include/unicorn/unicorn.h
	/usr/include/unicorn/x86.h
	/usr/include/unicorn/arm.h
	/usr/include/unicorn/arm64.h
	/usr/include/unicorn/mips.h
	/usr/include/unicorn/ppc.h
	/usr/include/unicorn/sparc.h
	/usr/include/unicorn/m68k.h
	/usr/include/unicorn/platform.h
	/usr/lib/libunicorn.so (for Linux/*nix), or /usr/lib/libunicorn.dylib (OSX)
	/usr/lib/libunicorn.a



[4] Cross-compile for Windows from *nix

  To cross-compile for Windows, Linux & gcc-mingw-w64-i686 (and also gcc-mingw-w64-x86-64
  for 64-bit binaries) are required.

	- To cross-compile Windows 32-bit binary, simply run:

		$ ./make.sh cross-win32

	- To cross-compile Windows 64-bit binary, run:

		$ ./make.sh cross-win64

  Resulted files libunicorn.dll, libunicorn.dll.a & tests/test*.exe can then
  be used on Windows machine.

  To run sample_x86.exe on Windows 32-bit, you need the following files:

   - unicorn.dll
   - /usr/i686-w64-mingw32/sys-root/mingw/bin/libglib-2.0-0.dll
   - /usr/lib/gcc/i686-w64-mingw32/4.8/libgcc_s_sjlj-1.dll
   - /usr/i686-w64-mingw32/lib/libwinpthread-1.dll

  To run sample_x86.exe on Windows 64-bit, you need the following files:
   - unicorn.dll
   - /usr/x86_64-w64-mingw32/sys-root/mingw/bin/libglib-2.0-0.dll
   - /usr/lib/gcc/x86_64-w64-mingw32/4.8/libgcc_s_sjlj-1.dll
   - /usr/x86_64-w64-mingw32/lib/libwinpthread-1.dll

  Then run either "sample_x86.exe -32" or "sample_x86.exe -64" to test emulators for X86 32-bit or X86 64-bit.
  For other architectures, run "sample_xxx.exe" found in the same directory.



[5] Cross-compile for iOS from Mac OSX.

  To cross-compile for iOS (iPhone/iPad/iPod), Mac OSX with XCode installed is required. 

	- To cross-compile for ArmV7 (iPod 4, iPad 1/2/3, iPhone4, iPhone4S), run:
		$ ./make.sh ios_armv7

	- To cross-compile for ArmV7s (iPad 4, iPhone 5C, iPad mini), run:
		$ ./make.sh ios_armv7s

	- To cross-compile for Arm64 (iPhone 5S, iPad mini Retina, iPad Air), run:
		$ ./make.sh ios_arm64

	- To cross-compile for all iDevices (armv7 + armv7s + arm64), run:
		$ ./make.sh ios

  Resulted files libunicorn.dylib, libunicorn.a & tests/test* can then
  be used on iOS devices.



[6] Cross-compile for Android

  To cross-compile for Android (smartphone/tablet), Android NDK is required.
  NOTE: Only ARM and ARM64 are currently supported.

	$ NDK=/android/android-ndk-r10e ./make.sh cross-android arm
  or
	$ NDK=/android/android-ndk-r10e ./make.sh cross-android arm64

  Resulted files libunicorn.so, libunicorn.a & tests/test* can then
  be used on Android devices.



[7] Compile on Windows with Cygwin

  To compile under Cygwin gcc-mingw-w64-i686 or x86_64-w64-mingw32 run:

        - To compile Windows 32-bit binary under Cygwin, run:

                $ ./make.sh cygwin-mingw32

        - To compile Windows 64-bit binary under Cygwin, run:

                $ ./make.sh cygwin-mingw64

  Resulted files libunicorn.dll, libunicorn.dll.a & tests/test*.exe can then
  be used on Windows machine.



[8] By default, "cc" (default C compiler on the system) is used as compiler.

	- To use "clang" compiler instead, run the command below:

		$ ./make.sh clang

	- To use "gcc" compiler instead, run:

		$ ./make.sh gcc



[9] To uninstall Unicorn, run the command below:

		$ sudo ./make.sh uninstall



[10] Language bindings

  So far, only Python is supported by bindings in the main code.
  Look for the bindings under directory bindings/, and refer to README file
  of corresponding languages.
