  • You will need to install Xcode from the App Store.After installing Xcode, make sure to install the command line tools by going to the Xcode preferences and under Downloads install the Command Line Tools components.

Installing required dependencies of EiffeStudio

MacPorts is a tool that allows you to use many Unix applications on the Mac. Before we can proceed with the installation of EiffelStudio, we need to install the required dependencies of EiffeStudio. First, install MacPorts.

Now simply type (from a bash terminal):

sudo port install pkgconfig
sudo port install bzip2
sudo port install xorg-libXtst
sudo port install gtk3                              

New required dependency for GTK3

sudo port install adwaita-icon-theme

Installing EiffelStudio from a compressed package

This section only applies if you have installed all the required prerequisites.

After downloading the compressed package, you should manually extract its contents to your hard drive. For example, you can extract it into /usr/local using the following commands (assuming that you have permission to /usr/local and that the installation package was saved in /tmp/Eiffel_X.Y.tar.bz2, where X.Y stands for the EiffelStudio version):cd /usr/local tar xvfj /tmp/Eiffel_X.Y.tar.bz2

This will install EiffelStudio files into /usr/local/Eiffel_X.Y . Once this is done, jump to the Setting up EiffelStudio section in order to complete the installation of EiffelStudio.

Setting up EiffelStudio

Once the files have been installed, you should define the following environment variables in order to run EiffelStudio:

  • ISE_EIFFEL to /usr/local/Eiffel_X.Y
  • ISE_PLATFORM to macosx-x86 for the 32 bits version or macosx-x86-64 for the 64 bits version or macosx-armv6 for the ARM version. We will be using macosx-x86-64 in the examples below.

and add $ISE_EIFFEL/studio/spec/$ISE_PLATFORM/bin to your PATH environment variable.

Using sh or bash as a shell, it suffices to type the following commands:export ISE_EIFFEL=/usr/local/Eiffel_X.Y export ISE_PLATFORM=macosx-x86-64 export PATH=$PATH:$ISE_EIFFEL/studio/spec/$ISE_PLATFORM/bin

Persisting Environment Variables

Se them up in the .bash_profile file once for good, so you don't need to set them up each time.1. Open the profile file into a text editor 2. Add the export command for every environment variable 3. Save your changes.To immediately apply all changes to .bash_profile, use the source command. source ~/.bash_profile

Starting EiffelStudio

Now everything should be properly installed and you should be able to run the compiler. Simply navigate to /usr/local/Eiffel_X.Y and double click the EiffelStudio icon.

Alternatively, you can also start EiffelStudio from the command line by entering the command estudio or use the command-line eiffel compiler ec.

If you are a new user to EiffelStudio, we recommend that you follow the EiffelStudio guided tour.
