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It’s probably Apple trying to tell you “Xcode is out of date”, but they should certainly show that in a more obvious way and redirect to the App Store that does show it: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