Error when trying to install rugged

[duser0]

Hey

I've been trying to install rugged for the last few days (Dandelion Deploy seems to have stopped working because of it)... I'm getting the following error though.

Please bear with me as not a backender at all. I have absolutely no idea how to fix it. I've tried reinstalling RVM, Ruby, Rails, Node, cmake, pkg-config... and nothing has worked. But the error persists!

gem install rugged
Building native extensions. This could take a while...

Oh and the mkmf.log file contains the following...

Tell CMake where to find the compiler by setting either the environment
variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
the compiler, or to the compiler name if it is in the PATH.

Hey @duser0, sorry for the trouble you've to go through installing rugged.

Which version of OS X are you running on?
Do you have the latest version of the XCode command line utilities (or XCode itself) installed?

[duser0]

Hey Arthur!

I was running Mac Lion 10.7.5 and XCode Version 2308...

I just updated to the latest possible XCode 4.6.3 and that fixed the problem!

(I could then install rugged, then dandelion and net-sftp and dandelion deploys again!)

Thank you for your time and help

No worries! 👍

I had the same issue. Solved by installing XCode command line utilities.
