Apparently the Opera Mobile Emulator is a 32-bit program and Ubuntu 13.10 no longer contains the "a32-libs" package to provide this support.

I have downloaded and unzipped the files, but when I try to run the emulator I get the following error message:

./opera-mobile-emulator-launcher: error while loading shared libraries: cannot open shared object file: No such file or directory

I have searched all over and have found all sorts of package-lists that one should install in order to run 32-bit programs on 13.10. I have tried several, but they have all failed because it seems that the list of packages that you need to run a specific program is specific to that program.

Does anyone know how I can get this to work?

This question came from our site for professional and enthusiast programmers.

Unless you are using an architecture different to the rest of your system just executing sudo apt-get install libqtgui4 should suffice.

In case that you are using another architecture just append :arch to the package name. Example, if you are using the 64-bits version then libqtgui4:amd64 is for you:

sudo apt-get install libqtgui4:amd64

That did the trick. Thanks a lot, Braiam! – Larry Dec 16 '13 at 13:46
If you are using another system (like ARM) try sudo apt-get install libqtgui4 – Nino van Hooff May 24 '15 at 20:06
