|
Hi.
I have a Raspberry Pi and I want to use Gentoo on it. I see two options and both seem impractical:
- compiling packages on the ARM (takes time)
- cross compiling on desktop Gentoo (annoying upload every time emerge something)
So I was thinking about two solutions:
- share the processing resources of my desktop over the network so the Pi can use it for compilation
- synching (in background, fast, automatic) between the cross-compiled binaries on the desktop and the Pi
Any other solutions, ideas ?
If any of these are good and easy to implement, could you give me any hings on where to start ?
Or maybe a binary distro for the ARMv6 ? Arch ? (please not Debian)
PS if the forum section is inappropriate, please move the topic |

I would do something like this:
script on Pi that calls $DESKTOP to build package using cross compile. Script handles all the details via ssh using public key authentication, or something. Once emerge completes, the binary is stored to a shared partition (samba, nfs, or somthing) and same script then installs the package on $PI. That way you use Gentoo, but everything is abstracted.
I wouldn't say Arch is not particularly reliable. I just had an update kill my shadow files. Honestly, the problem was NOT between the keyboard and the chair with that one.
Some script hints to get you going. I would call it compile.sh, just because.
Code: | #!/bin/bash
#log into compiling computer
echo "Starting login"
ssh <non-root user>@<some static ip>
echo "starting build"
# build package. Assume it is called 'xmerge'
sudo xmerge $1
# logout
echo "Build finished"
exit
echo "installing $1"
#install binary
sudo emerge -vg $1

And there you go! A simple emerge with only 1 command and also only 1 or 2 entries of your password depending on how you configure ssh.
For updates, you can do something similar, but first you need to process the output of emerge -quND world on your deivice (replace [ebuild ....] with =) _________________ First things first, but not necessarily in that order.
Apologies if I take a while to respond. I'm currently working on the dematerialization circuit for my blue box. |

Maybe because I've never used it and I don't know what it is I'll look into it. Thanks

Thanks It's a bit complex, but I'll consider it
btw... Does Tardis run on Gentoo ? xD |
