llvm-gcc-4.2: error

Question

The Project build & runs fine on a real device but a build for the iphone simulator finishes in this error 'llvm-gcc-4.2: error'. Any ideas?

llvm-gcc-4.2: error trying to exec '/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/../llvm-gcc-4.2/bin/arm-apple-darwin10-llvm-gcc-4.2': execvp: No such file or directory 
Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/llvm-gcc-4.2 failed with exit code 255

thx, Fabian

### XCode < 4.3.2 ###

After updating XCode from 4.2 to 4.3, I had exactly the same issue with lots of "unrelated" errors:

make[1]: /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.2: No such file or directory

Including a Command /Developer/usr/bin/clang failed with exit code 1 error.

I fixed that with:

cd /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin
ln -s llvm-gcc-4.2 gcc-4.2

### XCode >= 4.3.2 < 5.0 ###

After updating XCode to 4.3.2 and since it's now an App (not in /Developer anymore). Need to do these steps for both the simulator and the iOS device:

Fix the issue on the simulator:

cd /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin
ln -s ../llvm-gcc-4.2/bin/llvm-gcc-4.2 gcc
ln -s ../llvm-gcc-4.2/bin/llvm-gcc-4.2 gcc-4.2

Fix the issue on iOS devices:

cd /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin
ln -s ../llvm-gcc-4.2/bin/llvm-gcc-4.2 gcc
ln -s ../llvm-gcc-4.2/bin/llvm-gcc-4.2 gcc-4.2

### XCode >= 5.0 ### (11/03/2014)

Fix the issue on the simulator:

cd /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin
ln -s /usr/bin/llvm-gcc gcc-4.2

Fix the issue on iOS devices:

cd /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin
ln -s /usr/bin/llvm-gcc gcc-4.2

The first thing to do when things don't make sense is to clean the project (Product/Clean).

Also, look in /Developer/Platforms/iPhoneSimulator.platform ... etc and see if there is a directory or alias missing. Also open your target Build Settings and verify the paths under Search Paths.

Here's what my /Developer/Platforms/ looks like.

If you were like me you are upgrading a project.

Change your arch to arm7, which is now the standard I guess.
