When I tried to upgrade my system the other day I got the message
:: The following packages should be upgraded first :
pacman
:: Do you want to cancel the current operation
:: and upgrade these packages now? [Y/n]
This is nothing unusual per se, but what happened next was
resolving dependencies…
looking for inter-conflicts…
error: failed to prepare transaction (could not satisfy dependencies)
:: gcc: requires gcc-libs=4.7.0-3
The solution is
[root@hp ~]# pacman -S libtool gcc gcc-libs
:: The following packages should be upgraded first :
pacman
:: Do you want to cancel the current operation
:: and upgrade these packages now? [Y/n] n
So, you have to specify libtool, gcc and gcc-libs at one time, else you will
run into a cross dependency problem pacman seems to be unable to solve itselve.
When it asks to upgrade pacman first, you should say no.
After this, you can upgrade pacman, and the rest of your system without issues.
