Overview

This project was created with the goal of running Eiffel Studio natively on the Mac and succeeds the previous Carbon based EiffelVision implementation.

Build instructions

  1. Get the latest EiffelStudio for the Mac. If you have MacPorts installed you can do this by typing 
    port install eiffelstudio65
  2. Check out the latest source code from the trunk 
    svn co https://svn.origo.ethz.ch/eiffelstudio/trunk
  3. Set your EIFFEL_SRC and ISE_LIBRARY to the directory 
       export EIFFEL_SRC=/directory/to/your/checkout/trunk/Src
   export EIFFEL_SRC=$ISE_LIBRARY
  4. Locate EiffelStudio's config.sh file (probably /Applications/MacPorts/Eiffel65/studio/spec/macosx-x86/include/config.sh) and add the flag -ObjC to the definition of the ccflags, like this: 
       ccflags='-ObjC -pipe -no-cpp-precomp -fno-common -fPIC'
  5. Compile the C-parts of the library 
       cd $ISE_LIBRARY/experimental/library/objc_base/Clib
   finish_freezing -library
   cd $ISE_LIBRARY/experimental/library/cocoa/Clib
   finish_freezing -library
  6. Now open the .ecf file of your project and add the following line to your target: 
       <variable name="vision_implementation" value="cocoa"/>

    alternatively you can add another target which will allow you to easily compile both, a GTK+ and a Cocoa version of your application: 

       <target name="cocoa" extends="classic">
      <variable name="vision_implementation" value="cocoa"/>
   </target>

    If you want to compile Eiffel Studio there is already a target called "bench_cocoa" which you can select.

  7. Use ec -experiment (or estudio -experiment) to compile
