[solved] Package A depends on package B which depends on package A

Example: http://www.archlinux.org/packages/core/i686/openssl/
ca-certificates depend on openssl which (optionally) depends on ca-certificates.

There are more such situations. I'm curious why the dependencies are laid out like that.

Because that is what is needed.

I don't see the problem. Generally a dependency is needed for the program to run whereas an optional dependency would be for enabling additional features. ca-certificates needs openssl but openssl does not need ca-certificates.

Almost, since the ones I found were optional from one side, so to speak.

Don't see the issue. ca-certificate gives a plus to openssl and cannot be run without openssl. Any addon for some software will be referenced on the same way. Abiword-plugins obviously depends on abiword; abiword optionaly depends on abiword plugins which enhance its functionality.

I have a new example: http://www.archlinux.org/packages/extra/any/rhino/

[karol@black ~]$ pacman -S rhino
resolving dependencies...
:: There are 2 providers available for java-runtime:
:: Repository extra
   1) jre7-openjdk-headless  2) openjdk6

Enter a number (default=1): 1
warning: dependency cycle detected:
warning: jre7-openjdk-headless will be installed before its rhino dependency
looking for inter-conflicts...

[karol@black ~]$ pacman -S jre7-openjdk-headless
resolving dependencies...
warning: dependency cycle detected:
warning: rhino will be installed before its jre7-openjdk-headless dependency
looking for inter-conflicts...

The packages install fine in both cases.

The traditional way to solve circular deps are to install both in one go.

pacman -Syu rhino jre7-openjdk-headless

It just happens that pacman can in some cases, unlike most other package managers, handle circular deps on its own, as the previous post shows.

Just to close the thread, link to the integrity check report: http://mailman.archlinux.org/pipermail/ … 22698.html

Since this is a known issue, it will be presumably dealt with one way or another some day.
