Cocoapod lint error: [xcodebuild] No such file or directory

I just started learning how to write my own Cocoapod yesterday. There’s a great tutorial to get you started. However, I ran into an issue when trying to lint my new spec. It looked like this:

$ pod spec lint MyAwesomeLibrary.podspec

<p>-> MyAwesomeLibrary (0.0.1)<br />

<p>Analyzed 1 podspec.</p>

<p>[!] The spec did not pass validation.

When I manually ran the command in the above error message, I saw this error:

$ /usr/bin/gcc-4.2 -v -E -dM -arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk -x objective-c -c /dev/null 2>&1<br />
gcc-4.2: error trying to exec '/usr/bin/arm-apple-darwin11-gcc-4.2.1': execvp: No such file or directory

I don’t have the file “/usr/bin/arm-apple-darwin11-gcc-4.2.1”. If you see this too, you should check whether you have a preferred C Compiler. This is configured via the CC environment variable. Mine was set to gcc-4.2.

$ echo $CC<br />
gcc-4.2

To let cocoapods use the default compiler instead, just run the linter as

$ CC= pod spec lint MyAwesomeLibrary.podspec</p>

<p>-> MyAwesomeLibrary (0.0.1)</p>

<p>Analyzed 1 podspec.</p>

<p>MyAwesomeLibrary.podspec passed validation.

Woohoo! It passed!
