MacPorts and Clang

[Christopher Jones]

Hi,

/usr/bin/clang is the Apple system clang. You REALLY REALLY should not go fiddling with this. If you have changed it, change it back… Much breakage will occur if you do not.

Macports installs everything under /opt/local 

You can make a specific MacPorts clang version the default MP one using for example

 > sudo port select clang mp-clang-3.6

This will make /opt/local/bin/clang etc. point to the MP 3.6 clang version.

Then, to make this the ‘default’ you get at the command line, simply make sure /opt/local/bin is first in your PATH.
