Regarding compilation on Linux in debug mode (gcc 3.2),
I have extremely long linking phases, sometimes up to an hour
with my application :(. Is there a way to speed this up ?
Linking without debug info is much faster.

Must say the MS VC7 is much faster in this respect, at least 5 times.

I've got a 1GHz pentium with 256 Mb, which should be enough
(no swapping occurs).

That's absolutely right, and leaves the programmer some time to read mail
and newsgroups ;)

Except if you're actively developing the wrapper library and looking
for bugs in your code.

Ah, waiting for the laptop with dual P4, like to sit on the balcony while
coding. Especially when it's really nice weather outside.
