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

Solution

Make sure your config.sh was changed to allow compiling Objective-C (see step 4 above).

Problem

C compilation yields an linker error (symbols not found):

  Compiling C code in C1
  Compiling C code in E1
  Undefined symbols:
    "_bridge_void_general", referenced from:
        _bridge_void_general$non_lazy_ptr in Cobj160.o
    "_bridge_void_ptr_ptr", referenced from:
        _bridge_void_ptr_ptr$non_lazy_ptr in Cobj160.o
  ld: symbol(s) not found
  collect2: ld returned 1 exit status
  make: *** [ec] Error 1

Solution

Make sure you compiled the C-parts of the libraries (see step 5 above).
