Well, this is an autor-reply :)
Finally I found the package needed to run idl and load correctly the XML
module.
I use Ubuntu (Debian based) distribution and the magic package (among
others) is:
libstdc++2.10-glibc2.2
Bye.

Hi,
I've had the same problem for a while and threw it in the "too hard
basket". You don't just need libstdc++, you actually need libstdc++ as
it was packaged for mandrake and redhat. The distribution I use (gentoo) has a
compatibility package lib-compat - "Compatibility C++ and libc5 and
libc6 libraries for programs new and old". I recommend looking for an
equivalent package in your distribution.
If you can't find one then you need to install libstdc++ yourself.
I'm guessing that redhat/mandrake used libstdc++ for gcc 2.95.3 or
something close to that (Perhaps you can verify it with RSI).
You can get gcc from ftp://gcc.gnu.org/pub/gcc/releases/
Don't make the entire of gcc, just "make all-target-libstdc++".
Another option is to include the binaries themselves. There are numerous
versions floating around. For example:

> http://dev.gentoo.org/~eradicator/lib-compat-add.tar.bz2
As you can see, this is a general issue with migrating binaries from
redhat and mandrake.
Another thing to note is that there is a makefile in
/usr/local/rsi/idl_6.0/bin/bin.linux.x86
I wonder if it is possible to build objects like
libxerces-c1_7_0.so overselves so that we (and RSI) don't have to worry
about the compatibility libraries.
I can't really give a detailed way to solve this without knowing the
distribution. But I hope this post gives you a few options to get it
working.

It looks like you still have a problem with C++. The undefined symbol
"cout" is a symbol which should exist in the core C++ libraries. I
don't know where to go from here. ????

What version of libstdc++ did you install?
