 |
|
Hi Guys,
I've decided to install a clean Gentoo to my new rig, wich has an FX-8150 CPU and 16 gigs of RAM.
At the moment I just finished making the kernel. However I've noticed that the emerges are not working because I've set -march=bdver1 but gcc is only at 4.5.2.
I thought I could grab 4.6.2, no matter wether its stable or not, so I wrote
| Code: | | =sys-devel/gcc-4.6.2 |
into /etc/portage/package.accept_keywords.
I've tried many and many combinations, without the = sign, only typing sys-devel/gcc, giving these to package.unmask or package.keyword, anything i could imagine, yet portage does not want to pull ver 4.6.2, only 4.5.3-r1.
How the hell can I give him the order to pull that package? As I said I am in the middle of the installation, with the installation USB stick still in the PC.
Please help me, I would really love to try my new CPU wit all his features in my beloved Gentoo system.

| Outside of certain specific domains, such as scientific number crunching, it is rarely helpful to enable every last feature of your CPU. If you still want to use sys-devel/gcc:4.6, then provide the output of emerge --pretend --verbose sys-devel/gcc:4.6. This will tell you exactly why Portage is refusing to use a 4.6.x gcc. |

So you are saying that I wont see any gain by using gcc 4.6? I've read that the Zambezi chips require special care in multi-threading and task scheduling.
I typed in what you said, and portage hasn't found any result... It seems its not in the portage-tree somehow, although I did an emerge--sync just a couple of minutes ago.
But if it really does not give any boost, then its no point trying, better do the install the usual way...
UPDATE: Nevermind, I managed to grab it, thank you for your help!
