I've recently upgraded to a 64-bit machine (Kubuntu 12.04.02 AMD64) and in trying to assemble the list of things to compile some things I get conflicts. In trying to install lib64readline6
or lib64readline6-dev
I get:
The following packages have unmet dependencies:
lib64readline6:i386 : Depends: lib64tinfo5:i386 but it is not going to be installed
Depends: libc6-amd64:i386 (>= 2.11) but it is not going to be installed
I variously also try to include libc6-i386
(32 bit library for AMD64) as well as other combinations of things but I still get the conflicts.
