PC/SC support broken due to multiarch enabled libpcsclite1

[Tuomas Jormola]

At least in precise, libpcsclite1 provides the multiarch enabled shared library, e.g. /lib/x86_64-linux-gnu/libpcsclite.so.1 on amd64. However, the PC/SC module in opensc expects to find the library as /lib/libpcsclite.so.1 as demonstrated by this session in current precise with a SCR331 USB card reader installed. Also a local workaround by creating a symlink to the multiarch library is shown.

The shared library loading of opensc should be multiarch compatible.

This is affecting me too (Precise) and can confirm that the workaround works - thanks.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[ubu-user-1234 (rangelov-u)]

This affects me too (using ubuntu 12.04 beta 2).
Just some remarks:
1. This bug did not existed prior the latest updates (today I have updated and my card reader stopped worikng)
2. I am using a 32 bit ubuntu and the directories start with i384 rather then x86_64
3. The fix proposed by Tuomas Jormola works on my machine also

One other comment: While opensc-tool has a problem pcsc_scan is working perfectly (it is able to see my card => it is using the reader) - that is why I have decided that there must be a problem with opensc.

This should be fixed by resolving this:

It is a bug in OpenSC not pcsc-lite. See bug #978974
