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

• Get the latest EiffelStudio for the Mac. If you have MacPorts installed you can do this by typing

  port install eiffelstudio65

• Check out the latest source code from the trunk

  svn co https://svn.origo.ethz.ch/eiffelstudio/trunk

• Set your EIFFEL_SRC and ISE_LIBRARY to the directory

  export EIFFEL_SRC=/directory/to/your/checkout/trunk/Src
  export EIFFEL_SRC=$ISE_LIBRARY

• 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'

• 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

• 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.

• Use ec -experiment (or estudio -experiment) to compile
