MacOS Missing development tools #345

Closed jahvix closed 5 years ago

jahvix commented 5 years ago

I've followed the installation instructions, but running ruby extconf.rb yields the error:

Checking for float.h... /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/mkmf.rb:456:in `try_do': The compiler failed to generate an executable file. (RuntimeError)

This is on MacOS Mojave 10.14.

I'm not sure how to install the additional development tools required. I've installed Ruby development dependencies brew install ruby-dev and additional development tools via xcode-select --install.

Any suggestions?

bradwood commented 5 years ago

You probably need to install XCode from MacOSX App Store.

ecdemis123 commented 5 years ago

I am also having this same issue. Were you able to figure out a solution?

I already have XCode installed.

wincent commented 5 years ago

You could try xcode-select --install, which supposedly installs the BSD development tools as well. I haven't updated to Mojave myself, so I am flying blind as far as troubleshooting goes.

ecdemis123 commented 5 years ago

Thanks, I'll give that a try next. I'm upgrading Xcode right now to 10.1 so we'll see how it goes once I do that.

I've tried a couple of things from this thread but none of them have worked yet. https://github.com/wincent/command-t/issues/341

I'll update here when I figure out a solution.

ecdemis123 commented 5 years ago

This is what I did to get it working https://github.com/wincent/command-t/issues/341#issuecomment-457359052

Closing based on success reported in #341.
