It does help, and by telling me about gcc-config answers my 2nd |
| 10 |
question, how to switch. |
| 11 |
|
| 12 |
There's still my first question, though. These instructions assume I |
| 13 |
already have the gcc-5 ebuild, plus dependencies. If I do a normal full |
| 14 |
sync to achieve that, I already commit to going all the way. Presumably |
| 15 |
there'll be many packages in this update that will build-depend on the |
| 16 |
new gcc (especially those using C++), so I won't be able to just go back |
| 17 |
to gcc-4 by masking gcc-5 and proceeding as usual if something goes very |
| 18 |
wrong. |

What I hope for is a way to selectively download only the gcc-5 ebuild |
| 21 |
and its depndencies, which I could temporarily put in a separate local |
| 22 |
repo. Then, if the gcc update goes OK, I can move them in the normal |
| 23 |
portage tree and go ahead with the rest of the update. |

Thanks, and sorry for my extreme caution. With a source distro like |
| 26 |
gentoo a gcc upgrade is like a brain transplant. |
