LLVM GCC 4.2 Error Can't exec '/usr/bin/gcc-4.0' (No such file or folder)

Please help!!

I've upgraded from Snow Leopard to Lion (OSX 10.7.2) and then downloaded Xcode 4.2.1 successfully. However, when I created a new empty application without making any changes to the main.m or anything and click the Run triangle button, I got the build error. Can anyone help me out with this? I tried many things and they all failed.

* Reinstall 4.1 and then 4.2

* Uninstall 4.2.1 using the /Developer/Library/uninstall-developer-folders and reinstall 4.2.1

I cannot use Xcode for anything now. :-(

I guess you need to set the proper compiler.Go to Build Settings->Build Option->Compiler For C/C++/Objective C and set GCC 4.2 or System Default.

I did. It still failed for both compilers 3.0 or GCC 4.2. :-(

You mean you switched to GCC 4.2 and it still fails with a GCC 4.0 error?

If I use 3.0, it says "Apple LLVM compiler 3.0 Error, Can't exec '/usr/bin/gcc-4.0' (No such file or directory).

If I use gcc 4.2, it says "LLVM GCC 4.2 Error, Can't exec '/usr/bin/gcc-4.0' (No such file or directory).

Any clue?

Thanks!

Create a new project and see if that works.

Hi,

I did. I still couldn't compile any code. I remove all folders using sudo /Developer/Library/uninstall-developer-folder mode=all and reinstall Xcode 4.2.1. But the problem persists no matter how I tried. Does any one have the same problem? All these problem occurred after I upgraded Snow Leopard to Lion and Xcode 3 to Xcode 4.2.1. I also tried to install Ruby 1.9.3 and failed. That was my original reason to upgrade from Snow Leopard to Lion.

-Help!!
