GQRX fails to install

[doubleosixandahalf]

This is the output I get when I attempt to install GQRX, log file from "/opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_science_gqrx/gqrx/main.log" is attached. I have Xquartz installed so I dont know why im getting messages about xcode not being installed.

$ sudo port install gqrx

Xcode is not the same thing as Xquartz. What output does this command give?

xcodebuild -version

It looks like Xcode isn't properly installed ... might be Xcode itself or the Command Line Tools. Please verify that these are installed, e..g, per @jmroot's suggestion above.

Once you have Xcode and the CLT installed, try doing the following:

sudo port clean --all "gqrx*"
sudo port install gqrx

and see if that works. If not, please post the new log file.

Hmm, I just downloaded and reinstalled the latest version of Xcode and CLI tools that are compatible with Sierra, Xcode 9.2. I had installed Xcode years ago when it still came on the OS X DVD. Reinstalling Xcode / CLI Tools did not change anything.

Running "xcodebuild -version" outputs "xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance"

Running "sudo port clean --all "gqrx*"" and "sudo port install gqrx" still ultimately returns a "Error: Processing of port gqrx failed"

AH, got it working. I needed to run "sudo xcode-select -s /Applications/Xcode.app/Contents/Developer"
