Question

I been trying to install a port with the command sudo port install NAME_OF_PORT

The issue I am having with this particular port (OpenCV) is that it keeps asking me for dependencies with an error like the following:

Error: The following dependencies were not installed: libunwind-headers 
llvm-3.1 llvm_select

Is there any way I can sudo port install NAME_OF_PORT with all of its dependencies with just one command?

Thanks a lot for your time, any tip much appreciated.

Answer 1

Try running sudo port -v selfupdate and then rerun sudo port install opencv. If that’s not helping try running sudo port upgrade outdated to upgrade outdated dependencies.

Also take a look at this guide I wrote: Compile OpenCV (2.3.1+) for OS X Lion / Mountain Lion with Xcode
