[gentoo-user] Multiple versions of automake?

[Tanstaafl]

Hello,

I currently have 3 versions of automake installed (1.7.9-r1, 1.9.6-r3,
and 1.10.2).

emerge -pvuDN world shows an update available for each one, but, my
question is, do I need all 3 versions?

'equery depends automake' shows 44 packages, all depending on 1.10* or
higher.

So, can I safely emerge -C the other 2 versions? Should I (does it even
matter)?

Thanks,

Assuming you do not have those versions in world, the answer is:

yes

try running equery depends on a specific version or a SLOT.

equery lies through it's teeth. basically, it does a giant grep and tries to 
format the output sensibly. Oftentimes, it doesn't succeed in the "sensibly" 
department

No. The next emerge world will simply pull them back in. But they are build 
depends so stuff won't stop working

You're first step though is to check for a dodgy world file with cruft in it.

Probably won't matter.  A few packages actually specify an exact version
of the autotools, but most just want a certain minimum version.  If you
try to install such a package in the future it 'should' re-emerge the
required version of autoconf automatically.  It might matter more if you
want to install custom software independent of the portage system.

equery can be unreliable. If emerge --depclean -a wants to remove one of
both of them, let it, otherwise leave well alone.

Portage doesn't allow ebuilds to specify minimum versions or ranges for 
automake, only exact versions.

Specifying a mininum only works when putting automake as a dep in 
DEPEND.  However, Gentoo devs are required to use WANT_AUTOMAKE, not 
DEPEND and WANT_AUTOMAKE only allows specific versions, not minimum ones.

And this means multiple automake versions on the system are perfectly 
normal.

Ok, that's what I needed to hear... :)

Thanks Nikos...

Understood, thanks...

Just to be sure... the -a in the 'emerge --depclean -a' above will 'ask'
me if I want to continue and remove the packages it finds, correct?
Meaning, it won't just blindly go ahead and start ripping stuff out...

How does that differ from 'emerge -p --depclean'?

"emerge -p" will only print what it would merge/unmerge and then quits 
without asking.  You can run this as normal user, no need to be root.

"emerge -a" will print what it would merge/unmerge and then ask if you 
want to proceed.  You have to be root to use this command.

If you are not root and use "emerge -a", portage will turn it into an 
"emerge -p" and tell you that it did so because you are not root.

Saves you the time of running it twice if you decide to say "Yes"

Yes.

With -p you have to run the command again, and let is scan all installed
packages and their deps again, when you want it to actually remove them.
It's just a more efficient way of doing it.

Oops, I was actually thinking of how the autotools can specify minimum
versions of required libraries.  Libraries != autotools  :(

Well that was kind of obvious... ;) ok, thanks...
