Installing, Upgrading, and Uninstalling Macports

What is Macports?

• Macports is a software repository that ports Linux open-source software to be compatible with Macs.
• Examples of such software are gmt, nedit, ghostscript and gv.

Installing Macports on your Mac will allow you to have access to their repository and install ported Linux tools. You can also update any Macports software you installed via the appropriate port command.

Do I Need Macports?

• Macports is installed on every managed machine at IGPP.
• If you have a self-managed machine and need software like gmt, nedit, gv, etc. then you should follow this wiki.

Prerequisite: Install Xcode and Xcode Command Line Tools

1. A wiki on installing Xcode via the App Store can be found here: Installing Xcode Tools and X11
2. Prior to running these commands you should have:
3. Installed Xcode

4. Installed Xcode Command Line Tools.

   sudo xcode-select --install 
   sudo xcodebuild -license (type "agree" to accept license).
   open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg (10.14 and later)

Installing Macports

1. Download and install Macports from http://www.macports.org/ .

2. Sync your local software tree with the master repository using this command:

   sudo port -v selfupdate

3. This installs all the ports used at IGPP:

   sudo port install szip gdal +curl +geos +hdf5 +netcdf gmt5 gmt4 gawk ghostscript gv xorg-libXt +flat_namespace nedit g95 xpdf rsync sshfs geographiclib py27-obspy py27-numpy py27-scipy py27-matplotlib netcdf hdf5-18 ncarg gcc5 +universal sudo port install szip gdal +curl +geos +hdf5 +netcdf gmt5 gmt4 gawk ghostscript gv xorg-libXt +flat_namespace nedit g95 xpdf rsync sshfs geographiclib py27-obspy py27-numpy py27-scipy py27-matplotlib netcdf hdf5-18 ncarg gcc5 +universal

Installing GMT: An additional step is required for installing gmt4. Add the following line to your ~/.profile:

export PATH=/opt/local/lib/gmt4/bin:$PATH 

Explanation: By default, Macports and most ports install in /opt/local/bin and /opt/local/sbin. To let the computer know where to look for Macports and installed ports, a path is created in ~/.profile as such:

export PATH=/opt/local/bin:/opt/local/sbin:$PATH

This is automatically done for you when you install Macports.

However, gmt4 is installed in /opt/local/lib/gmt4/. Since this path isn't installed by default, you must manually create it in your ~/.profile so your computer knows where to look for it.

Upgrading Macports

These commands would be done if you wanted to keep your installed ports updated to the latest version.

1. sudo port selfupdate
2. sudo port upgrade installed
