=====Installing Eiffel under MacOs=====

See [[https://dev.eiffel.com/EiffelOnMac|here]]

=====Old=====
==EiffelStudio 14.05 on the Mac==

You can now install EiffelStudio via the Homebrew package manager. See [[http://dev.eiffel.com/EiffelOnMac|Eiffel On Mac]]. In brief:

  * install XCode
  * install XQuartz
  * install brew
  * run the following commands:

<code>
brew update
brew tap homebrew/x11
brew install eiffelstudio
</code>

The final steps will take quite a bit of time since we are recompiling the whole EiffelStudio delivery. Once done, you will have access to `ec', `estudio', and other executables in your path without having to set any of the ISE_EIFFEL or ISE_PLATFORM environment variables (they are automatically set for you when you launch those programs). 

==EiffelStudio 15.01 on the Mac==

 Until a Homebrew package is available do the following. It will take some time to update Macports:

  * Make sure you have the latest Xcode and [[https://www.macports.org/install.php|Macports]] 
  * Update [[https://trac.macports.org/wiki/YosemiteProblems|Macports for Yosemite]]. Download it [[https://wiki.eecs.yorku.ca/project/eiffel/getting_started:start|here]].

<code>
sudo port -v selfupdate
sudo port upgrade outdated
</code>


  * Download the latest EiffelStudio for MacOs [[ftp://ftp.eiffel.com/pub/download/15.01/|here]] (ftp as a guest/anonymous).
  * Unpack the tar file and place it in some reasonable place on your Mac, e.g. /usr/local/Eiffel_15.01.
  * Write a bash script and make it executable (or do the equivalent in your .profile)

<code>
#For Eiffel_15.01
export ISE_EIFFEL=/usr/local/Eiffel_15.01
export ISE_PLATFORM=macosx-x86-64
export PATH=$PATH:$ISE_EIFFEL/studio/spec/$ISE_PLATFORM/bin
/usr/local/Eiffel_15.01/studio/spec/macosx-x86-64/bin/estudio $1
</code>

Be sure to disable catcall warnings in the debugger/console at the menu Executions → Execution Handling.
