[help-3dldf] Re: HELP TO INSTALL 1.2.0.0 RELESASE.

[Laurence Finston]

Hi Marcel,

I had another couple of thoughts regarding the problems compiling
`parser.c++'.  This is the command that's used:
g++ -c -g parser.c++
On my system, no optimization is performed.  Perhaps
this has been changed in GCC 3.4.3, or it's set up
differently on your system.
g++ -c -g -O0 parser.c++
should ensure that it's not done.  However, if it doesn't work,
you should check the man page for `g++' on your system to see
whether it says anything on the subject.  Optimization can cause
a great increase in compile time.  I had this problem a few months
ago;  that's why I turned it off.

I think what may be happening is that your swapper is "thrashing",
i.e., the process is swapping pages in and out of main memory and
not performing any useful work.  If this is the case, it's probably
because GCC was configured with memory limits that are too low
to handle `parser.c++'.  I don't know whether this would be easy to
change or not.

If not using `time' and turning off optimization don't work,
and you're still interested in trying to install 3DLDF, I'll write
to the "help" list for GCC.  Maybe someone there will have a suggestion.
I'll try to reduce the size of `parser.c++' by removing debugging code,
but this will take several hours of work, and I don't have much time
to work on it now.
