Gentoo iBook G3 Cross Compiling?


Hi, I have been installing gentoo on my desktop for the past few weeks. (Not a whole lot of time to get to it) and I must say that I wished I had made the move a whole lot earlier. Anyway, my next canididate for gentoo would be my ibook g3 which has a slow processor. I have heard that for these systems cross compiling is a lot better of an option than compiling on the system itself. I have read the cross-compiling guide and am left a bit confused. Could I use my thumbdrive to transfer compiled binaries from my desktop to my laptop and install the packages that way? Also, what would I do when updates come out for my laptop. Is there any way of monitoring the package statuses?

Hi
All I can say about cross-compiling is that I tried to compile sparc64-binaries on a amd64-PC and that resulted in a huge mess. I think I will give it a shot again sometimes in the future but for the time being I don't feel like telling other people to do the same.

I installed Gentoo a few weeks back on a netbook having an Atom 270 and it worked fine - it just lasted 4 times longer than usual, but it was still acceptable.

What you could do instead of cross-compiling is to use "distcc" when you emerge something. "distcc" is fully transparent to "emerge" and it spreads out the compilation as well to other PCs connected to your network.

I used it on some PCs and it worked fine and it is for sure easier to use than cross-compiling, especially once you have a working environment.
The guide for distcc for cross-compiling: http://www.gentoo.org/doc/en/cross-compiling-distcc.xml
Hope it helps!
