How to build

System Requirements:


  1. Get source code by executing a following command in

    git clone --depth 1
    cd ShowyEdge
    git submodule update --init --recursive --depth 1
  2. Find your codesign identity if you have one.
    (Skip this step if you don't have your codesign identity.)

    security find-identity -p codesigning -v | grep 'Developer ID Application'

    The result is as follows.

    1) 8D660191481C98F5C56630847A6C39D95C166F22 "Developer ID Application: Fumihiko Takayama (G43BCU2T37)"

    Your codesign identity is 8D660191481C98F5C56630847A6C39D95C166F22 in the above case.

  3. Set environment variable to use your codesign identity.
    (Skip this step if you don't have your codesign identity.)

    export PQRS_ORG_CODE_SIGN_IDENTITY=8D660191481C98F5C56630847A6C39D95C166F22
  4. Build a package by executing a following command in

    cd ShowyEdge
    make clean all

    Then, ShowyEdge-VERSION.dmg has been created in the current directory. It's a distributable package.

    Note: If you don't have codesign identity, the dmg works only on your machine.
