[hubrix]

need to run
sudo gcc and agree to license terms
no error tells you about it

you get this

if you run gcc without root you get this message
which should be detectable

Agreeing to the Xcode/iOS license requires admin privileges, please re-run as root via sudo.

@hubrix Can you help me understand what documentation would have helped you understand this problem?

[hubrix]

So the error message is one of those that gives the user the wrong hint. I had development tools installed but had not agreed to the TOS. My recommendation would be to have extconf check for the error message from gcc. if it is "Agreeing to the Xcode/iOS license requires admin privileges, please re-run as root via sudo." it should spit out instructions to run "sudo gcc" and agree to the TOS.

I'm guessing this is not a gcc issue, but instead the situation where you haven't accepted the xcode EULA. Is this understanding correct?

The current tutorial advises users to run xcode-select --install which will prompt people for proper license acceptance. Did you do this? Did you see the "network problem" error that the following section covers?

[hubrix]

yes it is about not accepting the eula. i'm just saying the error message
could be better
