OSX 10.7, Xcode 4.6.2, icc 18.104.22.168
For some projects the compile errors aren't printed in log, can't be navigated with Xcode issues navigator and aren't hilited in sources. There is only a message "compilation aborted for <file name> code 2" - that's all. But all errors are printed as they should in .diag file. It looks like output is redirected to the .diag file no matter "Emit Diagnostics to File" is off. How to fix it?
Could you insert here the log from compilation with the error? (make sure you expand line starting with "CompileICC" in Log browser)
I would suggest using more recent version of compiler if possible, e.g. 15.0. There is a chance that it has no such problem.
