Try glibc-2.5-r1 and binutils 2.17.50.0.9. You may have to unmask them |
| 2 |
first. Also, to protect your system from human error, you may want to do it |
| 3 |
in a 32/64bit chrooted env. |

Hi all, |
| 23 |
|
| 24 |
I'm new to Gentoo embedded and fairly new to Gentoo, so I apologize if I am |
| 25 |
missing something obvious. I'm having trouble getting the crossdev toolchain |
| 26 |
up and running with a current portage sync. Could someone please point me |
| 27 |
in the direction of fixing this? |
| 28 |
|
| 29 |
Here's what I'm seeing: |
