I use OS X El Capitan. I installed Xcode 7 from AppStore and macports from an official website.

When I'm trying to install something using macports: sudo port install nodejs4, I'm getting the following warning: Warning: The Xcode Command Line Tools don't appear to be installed; most ports will likely fail to build.. But compiler (cc) works, make works, and I actually installed few macports packages without any problems.

Now if I run xcode-select --install, I'm getting dialog to install Developer Tools. But I think that Xcode already has all those tools:

$ xcode-select -p

So the question is: is it some bug in macports or is there some tools not included with Xcode 7 which must be installed separately using xcode-select --install? I don't want to introduce unnecessary clutter.

    If you open Xcode and go to Preferences, does it show command line tools installed? They aren't installed by default, just because you downloaded Xcode (in my experience). Commented Aug 7, 2016 at 20:33
  • @ruddfawcett I wasn't able to find anything about command line tools in Xcode 7. I remember that they were there in old versions, but now I can only see emulators and documentation for downloading. I think that Xcode now installs command-line tools automatically.

  • @user3439894 I will use Xcode regardless, I just don't want to install additional packages if it's not necessary. Command line tools seem to work fine, unless I missing some. But macports complain and I don't understand, why.

So I've inspected macports sources and it turns out that this warning is displayed, when directory /usr/include or executable /usr/bin/make is missing. While I have working /usr/bin/make, directory /usr/include was indeed missing. Installing command-line tools using xcode-select --install fixed it.

  • If that was indeed what solved your problem, consider accepting your own answer so that this question no longer shows up in the "unanswered" lists.

You have to install the developer tools to run the C compiler and other build tools (e.g. linker, make) from the command line and provide support files e.g. include and libraries

The command line tools are in places like /usr/bin and so installing via the AppStore cannot put the tools in the correct place. This a separate install step has to be done.

  • But those tools are working from terminal right now. There's /usr/bin/clang and it works, I can compile C programs. Same about /usr/bin/make, /usr/bin/xcrun, etc.

As a comment on the original question said, you must go to Xcode's settings, then to the last tab, Locations. The options for which command line toolset to use is there.

You must log in to answer this question.
