I develop 3DLDF on a computer running under Suse Linux, so that could
be a reason why you're having problems.  I would be very interested to
know what's necessary to fix them, though.

`ios' and `limits' are standard library header files.  They are either
missing on your installation, or the compiler isn't finding them.
The first thing to do is to determine whether they are available on
your system.  On mine, they are in the directory `/usr/include/g++/'.
If they are, you must make sure that the compiler finds them.  I believe
there's a way of doing this by setting an environment variable, but I
don't know off the top of my head, so you'll have to look this up (see
below).

There's also a GCC option for specifying a path to search for
including files.  This would be a bit more work because you would have to
add this option to the `AM_CXXFLAGS'
variable in `3DLDF-1.1.5.1/CWEB/Makefile.am', then run
autoconf && autoheader && automake && configure --prefix=<your path>
(I'm not sure whether `autoheader' is necessary, but it won't hurt).
This means you must have all of these programs.  I think you should,
but if you don't have CWEB, you might not have any or all of these
programs, either.

Before you do this, you should make sure GCC and the standard library is
up-to-date on your installation.
See `http://gcc.gnu.org/libstdc++/' and `http://gcc.gnu.org/index.html'
for more information.

Generally speaking, library headers with filenames that include an
`.h' suffix have been replaced by ones without a suffix, so if you
have `limits.h' but not `limits', this may indicate that your standard
library is out-of-date.  If you look at `loader.web', you will see
that when GCC 2.95 is being used, `streambuf.h' is included rather
than `ios'.  3DLDF will no longer compile with GCC 2.95.

My pleasure.
