) In this post, I will cover the following: Posted in code.The receipt in the image is from my wifeРІР‚в„ўs latest purchase from her favourite brand.Р”Р„fter using the receipt to learn image transformation, I finally feel that the purchase at the brand was worth the money. Ideally РІР‚Вbrew doctorРІР‚в„ў would have caught that I was missing the command-line tools that donРІР‚в„ўt get installed automatically with XCode 4.3. Searching on the text of the error led me to: Which convinced me that I was missing some fundamentals. Tiffgt.c:35:11: fatal error: РІР‚ВOpenGL/gl.hРІР‚в„ў file not found

Of course, it wasnРІР‚в„ўt, the key clue for me was finding this in the long stream of installation output: $ sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer I donРІР‚в„ўt have anything at /Developer, so I did this: Sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer If your Xcode is pre-4.3 or you installed the whole of Xcode 4.3 then one of Path at this time if you have *only* installed the Command Line Tools for Xcode. You should change it to the correct path. Warning: Your Xcode is configured with an invalid path.

Having additional scripts in your path can confuse software installed via Software packages are installed, and what additional flags to use when `./configure` scripts often look for *-config scripts to determine if Warning: РІР‚СљconfigРІР‚Сњ scripts exist outside your system or Homebrew directories. $ sudo chown sarah /usr/local/share/man/* $ sudo chown sarah /usr/local/share/man/de/* If a brew tries to add locale information to one of theseР”Вirectories, then the install will fail during the link step.

Install command-line tools from Р”В«efore I figured that out I fixed all of the issues found with РІР‚Вbrew doctorРІР‚в„ў If `brew doctorРІР‚в„ў does not help diagnose the issue, please report the bug: The first step of any solution, is, of course, understanding the problem. Along the way, I fixed a number of issues which took a bit of digging to find, so IРІР‚в„ўm leaving a little trail on the web in case other people run into the same things - or in case some inspired open source citizen has time to add better solution messages to brew. As with many install issues the root cause was actually pretty simple, but finding it was challenging. This is more about fixing my brew install, than about opencv.
