 Posted: Fri Jun 29, 2012 12:14 am Post subject: Use desktop PC to accelerate compiling on Asus Eee PC 1000H |
 |
|
Currently I am running Gentoo 64Bit on my desktop PC with an AMD FX-8120. Now I want to setup my Eee PC 1000H with Gentoo 32Bit, because every other distro just "feels" wrong! =) But compiling on my netbook would take a couple of time. So here is my question:
What would be the best way to use the power of my desktop PC to accelerate compiling on my Eee PC?
Thanks!

I have a similar setup, and use distcc and crossdev (on the desktop, to handle the difference between the hardwares). Though it's a bit involved, it makes recompiling chromium or KDE feasible; otherwise it would take more than a day

Does distcc has any disadvantages? Can you recommend a guide for setting up distcc with crosscompiling to me?

What other ways are there?
I read about icecream. Does anybody has experience with it?

I tried to set up distcc, but seems like it is not running. How can I find out misconfiguration?

emerge distcc
set up /etc/distcc/hosts
then make sure to add FEATURES="distcc" to make.conf
one other thing to note, using -march=native on your 32bit machine disables distcc
my personal preference is to just do a 32bit chroot on the 64bit machine (just untar a 32bit stage3 onto your 64bit machine, bind mount /proc and /dev, then linux32 chroot /mnt/gentoo32 /bin/bash (replace /mnt/gentoo32 with wherever youve untarred things), untar portage from within the chroot *after* chrooting, set up make.conf, build whatever you like)
build binary packages within the chroot, transfer them to the 32bit machine, done and done

It is recommended you post your errors here, only huge logs go to pastebin.
That said, isn't this error self-explanatory? You have to dedicate at least one helper with cpp option in your netbook hosts.
And you really should run emerge with -av to see what you are doing.

I changed my /etc/distcc/hosts to
| Code: | | 192.168.1.24,cpp,lzo |
then I tried again
| Code: | | pump emerge -avq gnome |
on my netbook but
doesn't display any task
Update:
I found the error. It's kind of embarrassing. 
http://bpaste.net/show/33813/
In line 14 was a typing error.
Now everything runs fine.
But I have got one more question: Is there a way to disable compiling on my netbook completely? Only my desktop PC should be used if it is possible
Thanks!

I couldn't notice a real acceleration of compiling with distcc enabled and for some packages I had to disable it to compile without errors.
Is the a measurable improvement of using chroot?

If you use the 32-bit chroot then you can practically duplicate the whole netbook in chroot with USE flags, etc. Just add FEATURES="buildpkg" to the make.conf in your chroot.
Then share your /usr/portage over NFS, mount it from your netbook and add FEATURES="getbinpkg" to the make.conf.
Alternative: I haven't tried it, but I see no reason why you could not be able to mount the / of netbook over NFS and use it as 32-bit chroot.

I would recommend icecream over distcc...when icecream works. Lesser configuration needed for icecream. Unfortunately, icecream is bug-riddled at the moment, and no one seems to be in a hurry to fix it.  |
