 Posted: Mon Feb 27, 2012 11:27 am Post subject: Moving Install to another Hard-Disk, CFlags/Cross Compiling |
 |
|
Ok so im setting up gentoo on an external hard drive from ubuntu. Once Im done i would like to remove ubuntu make a new partion table where ubuntu was and then copy gentoo over to the main hard drive on on the new partion table where ubuntu was. Can i just boot onto a live cd and use the cp command to do this, or is there a better way?
I do alot of kernel development for android and embedded ARM boards. Is the make.conf i set up going to interfere with my cross compiling? For instance i set my march to native, im not use to a global gcc config will my makefiles and cross compiler overide the make.conf? |

Is there a reason why you don't just boot the live cd and hose your ubuntu install then just do a normal gentoo install? btw if you need wireless support the sysresc cd is generally the best.

Im not hosing ubuntu becuase I have alot of work to do I cant afford to have my PC down. Im trying to take my time get all my flags optimized and make sure I have a full working version of X before I hose my current install. I just have to have access to my cross compilers, I cant afford to have my laptop down more than a few hours. Im also using this as a learning experince to try to port gentoo to another platform. I figure after i get the procedure down i can build ubuntu on a pc using my arm cross compiler for a board called the Raspberry PI.
What is the sysresc cd? Sorry for my ignorance. Also Im at the point of building my kernel and i see no drivers for my Atheros chipset wifi. Anyone know if there is some native drivers i can get or am i going to have to use ndiswrapper/madwifi or some crap like that? |

This will not be a problem. /etc/portage/make.conf controls the settings that Portage applies when it runs ebuilds. It does not have any effect on non-Portage compilations, whether native or cross.

System Rescue CD. What wifi chipset do you use? What is the output of lspci -k when you are running Ubuntu on that system? |

Ok well thats good then even when not using a cross compiler i can set up my own flags. As far as USE flags what happens if say you dont have something like alsa in your USE flags, does that mean nothing portage compiles will have sound support??
Well i have and Atheros AR9285 b/g/n card here is the output you asked for

As described in Definition of a USE flag, USE flags control optional behavior. Setting USE=-alsa will disable optional alsa support. If a package always supports alsa, then setting USE=-alsa will not disable it.

You need the ath9k driver to operate your wireless card. If I had to guess, I would say that this is the kernel configuration symbol CONFIG_ATH9K, described in menuconfig as Atheros 802.11n wireless cards support. |
