Apple LLVM compiler 3.1 error - iOS 5; Xcode 4.3

I have been receiving this error for a long time and I don't know what to do.

In order to keep the question short, I have written the error into a .rtf file and put it into CloudApp. Here's the link: http://cl.ly/0T3n1Q123u352T372t0m

I think it has something to do with "CLAPIDeserializer.m".

I will appreciate any help. Thank you.

Is this a project you made or one that you downloaded? It looks like one of the pre or post build scripts is unable to run. – borrrden

When this happens, close xcode and issue the "purge" command in Terminal then restart xcode. That solved this error for me.

It means your OS X kernel cannot spawn any more processes for your user ID. There is a maximum number of processes per user:

To see your process limitation:

sysctl kern.maxprocperuid

To check how many processes you have running:

ps aux | grep username | wc -l

To see how many zombie process:

ps -v -u username | grep -v grep | awk '{print $2}' | grep Z | wc -l

To see what they are:

for pid in `ps -v -u username | grep -v grep | awk '{print $1, $2}' | grep Z  | awk '{print $1}'`
do
  ps -o command="" -p $pid >> zombies.txt
done

None of these processes can be killed, and purge won't work on my mac, 10.8.2.

You could temporarily increase the max user processes count:

sudo sysctl -w kern.maxprocperuid=1024

Then in your .bash_profile or .bashrc add:

ulimit -u 1024

And change Finder’s limits:

sudo launchctl limit maxproc 1024

But really, it's time for coffee and give your mac a reboot..

I had this same problem with a project that I have under GIT with some of my team, the problem was that some of my team forgot to commit some new added files.

So, the .xcodeproj project it self was taking into consideration that it has some ViewControllers, but they weren't physically exist.

As soon as I added the missing view controllers, the project got built properly.

Hope this can help your situation.

I had to do a clean to fix this. product>clean from xcode. rebooting & purging didn't help, cleaning fixed it.

The message says

clang frontend command failed due to signal 1 (use -v to see invocation)

Try adding a "-v" to your "Other C Flags" under Build Settings of your project and see what it spits out...
