“Error: Xcode alone is not sufficient on Sierra.”

Posted by jpluimers on 2019/10/21

Once in a while, despite having Xcode, the Xcode command-line tools, homebrew and ruby installed on your Mac OS X / Mac OS / whatever it is called now, you get this on the console:

Error: Xcode alone is not sufficient on Sierra.
Install the Command Line Tools:
xcode-select --install

Running the commandxcode-select --install makes it even more confusing:

It’s probably Apple trying to tell you “Xcode is out of date”, but they should certainly show that in a more obvious way and redirect to the App Store that does show it:

Reminder to self: brew update needs re-accepting the xcode license agreement

Posted by jpluimers on 2017/09/29

Even though I have accepted this before, I needed to accept it again:

$ brew-update-ugprade 
Error: You have not agreed to the Xcode license. Please resolve this by running:
  sudo xcodebuild -license accept
$ sudo xcodebuild -license accept
Password:
$ brew-update-ugprade

How-To: Create a free Apple developer account for sideloading apps | 9to5Mac

Posted by jpluimers on 2017/02/16

Interesting: Starting with Xcode 7, Apple made it possible to sideload apps on the iPhone, iPad, and Apple TV using a free Apple ID. Although a paid developer account is still required to deploy apps to the App…: How-To: Create a free Apple developer account for sideloading apps | 9to5Mac

Ken Thompson – quotes – Reflections on Trust

Posted by jpluimers on 2016/12/21

Some of the Ken Thompson – Wikiquote¬†entries come from a great 1983 ACM Turing Award Acceptance Lecture “Reflections on Trusting Trust”.

That lecture used to be on http://cm.bell-labs.com/who/ken/trust.html

But it isn’t, and it’s not in the WayBack machine¬†and neither in the Google Cache because of the robots.txt. Historic link rot galore!

The lecture is about compiler viruses and viruses actually did this at least a few times: Delphi in the 2009 and to XCode in 2015.

A few nice links from ACM Classic: Reflections on Trusting Trust РGoogle Groups though:

And archived versions of (I hope accurate) copies of the article:

Finally I found a PDF copy of the original ACM prints¬†that Greg Ganger¬†of¬†Electrical and Computer Engineering at Carnegie Mellon University¬†has online. It’s archived too.

`xcode-select –install` required for OS X 10.9 Xcode command-line tools (like `zlib-devel`)

Posted by jpluimers on 2016/11/16

Hopefully this was a one time oversight from Apple, but on OS X 10.9 (Mavericks) the Xcode command-line tools cannot be installed from the Xcode Preferences pane.

You have to install them from the command-line:

xcode-select --install

There is one catch though: it might fail as you first have to start Xcode once and accept the license agreement.

You need them for instance when playing with zlib-devel (for instance when creating your own openssl builds).
