I do not understand that. I've compiled qt and got the shared libraries. The
programs in qt-2.3.0/examples work fine. They are all dynamically linked
against libqt. That's why I would say icc is able to produce shared libraries.
Or have I missed something?

What do you mean by supporting static objects? A link would be sufficient.

I would expect that libtool is able to learn a new compiler. This seems to
be a minor problem.

I've read a lot about gcc's terrific c++ implementation. That's why I expect
a performance boost with platform specific binaries compiled with icc. Even
people with Athlon processors should profit because icc's i386 code much is
better than g++ one's.

Unfortunately I cannot remember the link, but Intel said something about up
to 30% faster binaries. There is one Document, which describes some
performance issues of
icc:

http://developer.intel.com/software/products/compilers/linux/opt_convert_linux.pdf

Till now I can only state that compiling qt was much faster than with
gcc/g++ (7 min instead of 12 min), but this is not representative.

Thanks

Christoph
