I know that you can do a emerge -u to update system or world but I read a post somewhere about doing a emerge -deep. I was wonding what the deep option does cause i cant find any documention on it. I have notice that if you do emerge -up the packages all have U's and if you do a emerge -p -deep there is a much longer list but they all have N's. At first I thought that the if you did emerge -u -deep if just updated more packages but again they all have N's not U's.

thanks

Hi,

the --deep method was introduced and you can do the following with it:

If you do emerge -u world it just updates the things listed in the world file and _not_ the dependancies (only if the updated package in the world file needs a newer package as a dependancy) and with --deep you tell emerge to update all packages and not just all packages listed in the world file...
(before --deep was introduced some people just added every installed package to the world file to -u world everything automatically...)

Another use is for emerge -e world...emerge -e world just recompiles all packages not compiled with your current set of gcc etc. but if combined with --deep everything is recompiled...

I am not 100% sure, though...Even if I am wrong (please someone correct me then) I think you can get a general idea of what the use of --deep can be usefull...

First, don't get confused about the number of hyphens: there are two. --deep. -deep is the same as -d -e -e -p, which includes -e (emptytree) and will recompile everything.

I am not sure, though.

I just heard from a user in IRC when he does
emerge -e world
he gets informed on all packages which are already current that he should touch the ebuild to recompile, but with --deep it worked for him - that's the only explanation I have for this...I can't say it from my point of view though...so it's more a guess - but as I said...don't blame me on this one

Only thing I could find that depends on sylpheed is sylpheed-iconset. Got that?

If I type "emerge --pretend --emptytree world", then the result is a listing of every package installed on my Gentoo Linux box?

Okay, I'd like to extend the question, then.

I just found a thread on "--deep" from back in October in which somebody says that you can occasionally get in trouble doing "emerge --deep --update world" because a library might be recompiled and a third package might still want the library compiled in the old way.

I'm interpreting this to mean that the only way to get around that is to use "emerge --update --deep --emptytree world" ... which could take days on my PIII/500MHz box!

Am I understanding this correctly?

TIA,
-Robert
