error: compiler is out of heap space , Vtk + Opencascade

Hi Sir!

i can't compile because the follow error is occurred.
fatal error C1060: compiler is out of heap space
Error executing cl.exe.

I use vc6.0 and I use the Opencascade plus vtk.

Without Vtk setting, I can compile Opencascade.
But, with vtk setting, i cannot compile.

after vtk forum search, i found the VTK_USE_ANSI_STDLIB complie option.
so I add inclued "VTK_USE_ANSI_STDLIB" in my project
but no effect.

and I add inclued /Zm1000 in my project.
but error: compiler is out of heap space displayed.

Help me..
i don't know how do i solve this problem.

thanks in advanced.

I'm also a OCC newbie, but I know that it is a HUGE project. And VTK is pretty huge too. So the cheap solution might be to simply add more physical memory (RAM)? A more manual solution might be to compile each lib individually (cd lib xx; make), then link everything (not statically, of course, as it will make a HUGE exe you might not be able to execute because of insufficient RAM). I hope this helps.

I always wondered, what is the difference between OCC and VTK? I mean, why use 'both'? My impression (so far) is that their functionalities overlap pretty much. I mean, you essentially can draw in 3d space with either one. OCC has better CAD-like demo, while VTK's medical visualisation is more impressive (and python support :). Oh yeah, VTK has also some nice books published, and community seems a little more active, but maybe that's just my impression.
Well, just wondering.

Out of curiosity, how 'long' does it take you to compile OCC libs
(what processor and how much physical RAM are you using)?

have tried building the workspaces one after each other? So don't use OCC.dsw but the smaller ones and build OCC with these workspaces?
As far as I know is "VTK_USE_ANSI_STDLIB" for newer compilers loke VC7
