Dear maintainer, thanks for your help ! I found the problem and resolved it - the bug can be closed !
The problem was, that I did not realize (and no one told me - even not the maintainers after the explizit question why "/usr/lib32/ is not existent" ;-) that during an update of "multiarch" and the "ia32-libs.." the folder "/usr/lib32/" moved to "/usr/lib/i386/linux-gnu/" After realizing this, it was very easy to set the correct links to make ADS2012 work again ! ln -s /usr/lib/i386-linux-gnu/libXm.so.2 /usr/lib/i386-linux-gnu/libXm.so.3 ln -s /usr/lib/libXm.so.4 /usr/lib/libXm.so.3 did it. Dear Goswin, one last question on this topic: When (version or date) was "/usr/lib32" replaced by "/usr/lib/i386-linux-gnu" ? Best regards Holger
