Compiling For Zubuntu, g++ too slow Options

[walkman]

Hello,
first of all, thanks a lot for the great Zubuntu distro. What I need just works™ ;-).

This is the first time I am trying to compile something on my Zaurus, which I actually acquired some time ago mainly in order to port my own software to ARM based platform and to play with it. I have a rather small project written in C++ heavily using Boost libraries and packaged with autotools chain. No problem under Zubuntu, configure worked perfectly, even a devel distro build (after I downloaded and compiled libtool2 which went as a breeze - well, pure C). Now the poor gadget is fighting with my code already since 3 hours and still it did not finish crunching the first(!) cpp file. When I check it with g++ -E ..., I can see that the piece after expanding all the macros has 60k+ lines in C++. Well, there are bigger still to come...

What can I do to speed up the compilation process? How do you guys compile large C++ codebases? Overclocking doesn't seem to be an option, so with this speed of progress, if I am lucky, I will probably wait about a week until my smallish program (it has about 5k physical source lines of code) compiles and links.

Is there perhaps some quick and dirty manual for cross-compiling for ARM (in particular Zubuntu 1.0)?

Thanks for any advice,

Peter.
