Has anybody ever succeeded in building Qt 3.x on Linux using ICC 7+ with all the optimizations enabled?
I tried many times - most of the time the compile process gets stuck - mcpcom keeps on taking 90% CPU and it never ends. Some times It did build it successfully after disabling ip and ipo but applications segfault. I have similar experience with the Open Source ORB TAO.
In my $0.002 worth opinion, Intel C++ compiler hasn't yet reached the maturity of GCC - at least not on Linux. It can't compile any complex software (ACE/TAO, Qt etc.) with optimizations enabled. Even if it does, the compiled software hasn't worked. To file a bug report at Intel, you require premier support or some such thing. That's the sole reason the compilers aren't improving by each release.
