• Get prebuilt binaries from Releases page
• ...or build yourself an executable in the platform of your choice.

ccipher requires cmake and a C 11-compatible compiler to be available inside your PATH environment variable.

To test whether you have it :

• Fire up a terminal.

• Enter cmake --version to test CMake. On GNU/Linux it should yields a result like this :

  cmake version 3.12.1
  
  CMake suite maintained and supported by Kitware (kitware.com/cmake).
  

• Enter g -v to test GCC suite. On GNU/Linux, you should see something like this :

  Using built-in specs.
  COLLECT_GCC=g  
  COLLECT_LTO_WRAPPER=/usr/lib/gcc/x86_64-linux-gnu/8/lto-wrapper
  OFFLOAD_TARGET_NAMES=nvptx-none
  OFFLOAD_TARGET_DEFAULT=1
  Target: x86_64-linux-gnu
  Configured with:
  ...
  Thread model: posix
  gcc version 8.2.0 (Debian 8.2.0-5)
  

• (Only if g isn't there)

  Type clang -v or clang --version to check if Clang is available. It should yields things like

  clang version 6.0.1-6
  Target: x86_64-pc-linux-gnu
  ...
  

• If you fail to successfully run any command of the above, see section "Fulfilling requirements" below.

• Fire up a terminal.

• Change the current directory to be the root of this repository.

  • git clone https://github.com/42tm/ccipher beforehand, if necessary.

• Make a directory there. Here I assume you used a directory called build/.

• Change current directory to it.

• Enter the following commands:

  cmake .. # Create Makefile

  • There are 2 options to build:
    • Release: -O3

    cmake -DCMAKE_BUILD_TYPE=Release ..
    

    • Debug: -g

    cmake -DCMAKE_BUILD_TYPE=Debug ..
    

By default, when run cmake .. without specific build type,

• If no build option was chosen in the past, cmake will try to build this repo in Release
• Else cmake will select last build type

• There should be build file for you after running CMake. Now run it:

cmake --build .

Now you should see an executable named ccipher inside your current directory (or ccipher.exe in case you use Windows).

• CMake : download from here.
• C -11 compatible compiler :
  • On Windows, try MSVC, Clang or MinGW-w64 GCC.
  • On GNU/Linux, try any compiler you want.
