Eclipse ADT Error: Cannot run program adb

Question

I'm on Ubuntu and just installed the Android SDK ("SDK Only") for 64-bit linux. I then installed the ADT plugin for Eclipse. When I restarted Eclipse it asked me to open the SDK Manager and install some OS SDKs, so I installed some Developer tools and the most recent (I believe it was 4.2.2) Android distro. I then restarted Eclipse and got no errors or console warnings.

I then tried to open several Android views (Heap, LogCat, etc.) and got the following error:

What is this and why am I seeing it? What can I do to correct it? Thanks in advance!

Update: running an ls -l on the directory in question produces:

Answer 1

What is your Ubuntu Version ? Before ubuntu 12.04, you must install ia32-libs

sudo apt-get install ia32-libs

Answer 2

If you're on ubuntu 13.10 (and possibly other versions >= 12.10), you may need to install

apt-get install lib32ncurses5 lib32stdc++6 zlib1g:i386 libc6-i386

in stead. ia32-libs is no longer available on 13.10
