[gentoo-user] libtool 2.x upgrade

[bn]

Hi,

I have a stable x86 system that requires still a bit of updating, among
those libtool and gcc. Since I need the system to be usable *now* for
work reasons, I don't feel like updating gcc and rebuilding it all with
an emerge -e system / emerge -e world, but more and more packages want
to upgrade to libtool 2.x

Is it safe to upgrade libtool without (1)rebuilding gcc too and
(2)rebuilding system/world?

thanks,
m.

I don't know, but for this type of scenario you are better off building 
binary packages of everything that need to be updated without actually 
installing any of it on the machine.  At the end, when all binaries have 
been created by portage, you can install them in one go at a convenient 
point.

Look up the "--buildpkgonly" option of emerge for this.

FWIW I've been using Libtool 2.2.6b since 091212
& GCC 4.3.4 since 091018 without any problems I can remember;
I kept GCC 4.1.2 installed as well & use 'quickpkg' to make back-ups.
You shouldn't need to rebuild anything else till it comes up naturally.
I never do 'emerge world' without '-Dup', but emerge pkgs individually.

GCC is slotted, so you can install the latest version but switch back to
the old version instantly if it gives you problems. Unless the is an ABI
change, which hasn't happened for a while, it is not necessary to rebuild
everything.

Looks like an excellent suggestion, I didn't think of that. Thanks!

Anyway, if someone else knows the answer to the libtool question, I'd be
happy, if only for learning purposes :)

That's exactly what I wanted to know. But it strikes me that from
libtool 1.x to 2.x there's no ABI change. Is this correct?

I don't know exactly what libtool does (I'm not a C programmer -well,
apart from very basic stuff), but in general major version updates break
compatibility, therefore my concern.
