Hi,
I have an conflict wth 2 Versions of Readline:
(sys-libs/readline-5.2_p12-r1::gentoo, installed) pulled in by
=sys-libs/readline-5* required by (dev-lang/ghc-6.8.2::gentoo, installed)
(sys-libs/readline-6.2_p1::gentoo, ebuild scheduled for merge) pulled
in by =sys-libs/readline-6.2_p1
Is ts possible to install both libraries in the same time?
Yes. Portage can support different versions side-by-side if the ebuild
makes use of the SLOT variable. For instance, I have
sys-libs/readline-6.2_p1 installed and attempting to install readline-5*
yields:
Calculating dependencies... done!
[ebuild NS ] sys-libs/readline-5.2_p14:5 [6.2_p1:0] 2,024 kB
Note that this isn't a downgrade in so far as 6.2_p1 won't be removed.
It's a new, slotted instance of the package. No problem there.
hangeLog: Stabilize old ABI SLOT version.
readline-4.3_p5.ebuild:SLOT="${PV:0:1}"
readline-5.2_p14.ebuild:SLOT="${PV:0:1}"
readline-6.1.ebuild:SLOT="0"
readline-6.1_p2.ebuild:SLOT="0"
readline-6.2.ebuild:SLOT="0"
readline-6.2_p1.ebuild:SLOT="0"
readline-6.2_p1-r1.ebuild:SLOT="0"
readline-6.2_p4.ebuild:SLOT="0"
it seems to be that in my case readline-5.2_p12-r1 ist installed under SLOT 0.
can i override the slot-variable ?
I gather that you've synced so if you run emerge -a1 '=readline-5*',
that should install the latest 5.2_p14 ebuild which is appropriately
slotted.
Note that the latest stable version of ghc (6.12.3-r2) doesn't depend on
the old version of readline anyway. The main issue was that your portage
tree was out of date. Now that has been dealt with, I think you just
need to upgrade as normal. You can uninstall the old instance of ghc
before allowing it to re-install, in case it still blocks.
