Numbers don't count -- it's focus. There are maybe 5 portable GUI libraries
you could go evaluate for C++ -- in JAVA it's much simplier. And despite the
large numbers of libraries, I think almost no-one can argue that one might use
C++ to implement a web server backend these days. Sad because this is one of
the places I would expect C++ to have an upper hand on JAVA.

I agree these are barriers.

Well we can debate what's low level. For example, consider getting stuff out
of a database 'low level', but essential to applications of all sorts.
Certainly there are several libraries out there, with varying degrees of
standard library integration, portability, licensing, etc. Nothing even close
to 'standard'. This is just standard stuff in JAVA, Perl, etc.

That could be useful. Like CPAN I think you would need to be able to run a
few simple to understand commands to retrieve a new library into your library
set. A kind of distributed bcp perhaps.

No question portability is more difficult...
