Out of memory compilation

[Akanksha]

Hey!

I have a little problem here.. I am trying to compile a huge C++ code
of about 2 lakh lines and the compilation gives me the following error

cc1plus: out of memory allocating 42381928 bytes after a total of
391704576 bytes
make: *** [model_1.o] Error 1

I am running this on a server with 4 GB RAM..

The code uses ILOG libraries.. ILOG is a licensed constraint solver...

Why would a code compilation need so much memory and how can I find
where exactly is it consuming so much memory?

I had to Google for that (my knowledge of languages of the Indian
subcontinent being non-existent). Would I be right in saying that 1 lakh
= 100,000?

lines and the compilation gives me the following error

That's a fair wack of memory to run out of...

You'd probably be best to ask on a forum for your compiler (I'm guessing
GCC, so maybe try gnu.gcc.help or the GCC mailing lists).

Yea.. its 100,000 :)

I am using g++ which is why i posted here.. I ran a verbose mode and
it apparently takes max time in expand and combining.. I dont know
what that is.. Could anyone tell me where exactly does a compiler eat
memory?

Yes. Someobody could tell you. In a news group dedicated
to your compiler and platform.

Search at groups.google.com for news groups that talk about
your compiler.

Also, don't top post. Top posting allows the Vorlons to
contact the foul Marmidons. And nobody wants that.

Not even the Vorlons.

Please don't top-post... like I'm doing now ;-)

Rearranged.

If you're using g++ and the issue is compiler-specific (which it is and
therefore off-topic here), then why didn't you try on a GCC/g++ newsgroup
as suggested?
