Hi Troy,
We did quite a bit of work in this area. The result of this work
is in ROOT 4.00/02. Could you please try to upgrade and let me
know if your still have problem?
Note that in 4.00/02 the std::string dictionary has move from
the cintdlls to the libCore.dll.
Cheers,
Philippe.

It also works fine under root 3.10.02 as well, of course, it was just
failing on my particular machine. The "cout" was just an example that
something about strings appeared to be screwy. The real problems were
in passing strings to functions and getting automatic type conversion
from C string literals ("these") to string types, as in:
void takesastring(const string &);
takesastring("foo");
which were failing as well. So the c_str() workaround worked, but
that wasn't the point. I should have been clearer.
But anyway I found the problem. As it turns out, on my machine,
string.so in "cintdlls" fails to build, but the error is ignored and
the compile keeps going, ending up in a faulty installation of root.
Installing the binary distribution fixes these problems. I'm fine
using the binary distribution, and I would find the string::iterator
problem myself (no time right now), but in case anybody wants to chase
down this error, I'll include it. I got this error with root 3.10.01
and 3.10.02, using gcc v.3.3.2 and v.3.2.3. Glibc version 2.3.2.
(Yep, I did quite a lot of compiling, and every time the error flew by
without my seeing it.)
Cheers,
Troy
