OSCAR Build Instructions for Mac

Prerequisites

• Qt 5.12.8 (the current LTS release as of OSCAR 1.1.0)
• macOS 10.12 Sierra or higher for building (required by Qt 5.12)
• Command-Line Tools for Xcode 9.2, and optionally Xcode itself
  • Xcode 9.2 is the last version that runs on macOS 10.12
  • Xcode 10.1 is the last version that runs on macOS 10.13
  • Xcode 10.3 is the latest version that runs on macOS 10.14

NOTE: Official builds are currently made with macOS 10.14 Mojave and Command-Line Tools for Xcode 10.3.

Setup

1. Install Mac OS X 10.12.6 Sierra (or later) and apply all updates.

   • Optionally create a "build" user.

2. (Optional) Install Xcode 9.2 (or later, if using a newer version of macOS), approx. 7GB:

   1. Open Xcode_9.2.xip to expand it with Archive Utility. This will take a while.
   2. Delete the .xip archive.
   3. Move Xcode.app into /Applications.
   4. Launch Xcode.app and agree to the license.
   5. Uncheck "Show this window..." and close the window.
   6. Xcode > Quit

3. Install the command-line developer tools, approx. 0.6GB:

   1. Launch Terminal.app and run:

       xcode-select --install
      

   2. Click "Install".

   3. Click "Agree".

   This will download and install the latest version of the Command-Line Tools for Xcode for your version of macOS, without requiring a developer account.

   Alternatively, the command-line tools installer .dmg can be downloaded from the Xcode download site, but you will need a (free) developer account and will need to pick the appropriate download for your version of macOS.

4. Install Qt (as "build" user, if created), approx. 3GB:

   1. Mount qt-opensource-mac-x64-5.12.8.dmg
   2. Launch qt-opensource-mac-x64-5.12.8
   3. Next, Skip, Continue, (optionally change the installation directory), Continue
      • Qt is entirely self-contained and can be installed anywhere. It defaults to ~/Qt5.12.8.
      • If you only have the command-line tools installed, the Qt installer will complain that "You need to install Xcode and set up Xcode command line tools." Simply click OK.
   4. Expand Qt 5.12.8 and select "macOS", Continue
   5. Select "I have read and agree..." and Continue, Install
   6. Uncheck "Launch Qt Creator", Done
   7. Eject qt-opensource-mac-x64-5.12.8

Build

1. Build OSCAR:

    git clone https://gitlab.com/CrimsonNape/OSCAR-code.git
    cd OSCAR-code
    mkdir build
    cd build
    ~/Qt5.12.8/5.12.8/clang_64/bin/qmake ../oscar/oscar.pro
    make
   

   The application is in OSCAR.app.

2. (Optional) Package for distribution:

    make dist-mac
   

   The dmg is at OSCAR.dmg.

(Optional) Using Qt Creator

1. Launch Qt Creator where you installed Qt above, by default ~/Qt5.12.8/Qt Creator.app.
2. File > Open File or Project... and select ~/OSCAR-code/oscar/oscar.pro (or wherever you cloned it above), then click "Configure Project".
3. Configure building:
   1. Click on "Projects" in the left panel.
   2. Under Build Settings, in the "Edit build configuration" drop-down menu, select "Release".
   3. Click to expand "Details" for the qmake build step.
   4. Uncheck "Enable Qt Quick Compiler", click "No" to defer recompiling.
4. Configure packaging for distribution:
   1. Click "Clone..." to the right of the "Edit build configuration" drop-down menu.
   2. Name the new configuration "Deploy".
   3. Click to expand "Details" for the Make build step.
   4. Set the Make arguments for the Make step to "dist-mac".
5. To build OSCAR, select "Release" from the "oscar" button in the left panel. Then select Build > Build Project "oscar". The application is in OSCAR.app.
6. To build OSCAR and package for distribution, select "Deploy" from the "oscar" button in the left panel. Then select Build > Build Project "oscar". The dmg is at OSCAR.dmg.
   • Progress in "Compile Output" will pause for several seconds while "Creating .dmg". This is normal.
