This may be a real problem, or it may be just the `time' command.
On my machine, it takes slightly over a minute.
`time' isn't needed.  It just tells me how long the compilation takes.

Try making this change in `3DLDF-1.2.0.0/CWEB/Makefile.am':

Replace this:

parser.o: $(3dldf_header_timers) parser.tby prbsnflx parser.c++
        @echo "Compiling \`parser.c++'.  This may take a minute or so ..."
        time $(CXX) -c -g parser.c++

With this:

parser.o: $(3dldf_header_timers) parser.tby prbsnflx parser.c++
        @echo "Compiling \`parser.c++'.  This may take a minute or so ..."
        $(CXX) -c -g parser.c++

If this isn't the problem, then it's the size of `parser.c++'.  However,
if GCC was configured on your system with insufficient memory limits to
process it, I would expect it to exit with an error message.

`parser.c++' can't be broken into units for separate compilation, because
it's generated by GNU Bison.  I've been working on removing debugging
code from the parser actions and replacing the remaining code with
function calls.  The functions can be defined in other files.  Along
with not using optimization, this has helped to reduce compilation time
for `parser.c++':  down to slightly over a minute from about 10 minutes
on my system.  However, there are a lot of parser input files, and it's
rather time-consuming (and boring) to make these changes.

In short, please get rid of the call to `time', and let me know if
it doesn't work.

Thanks.
