Any way, after upgrading to 64 bit Ubuntu a while back and trying to run ./ccxstream from command line, I got this error:
./ccxstream: error while loading shared libraries: libreadline.so.5: cannot open shared object file: No such file or directory
I've gotten this error before and since then forgot how to fix it, so I'm putting it up here in case I one day forget again. The fix for this problem is to install the appropriate libreadline file, which can be done by:
bryan@SERVER-UBUNTU:~/$ sudo apt-get install lib32readline5
Reading package lists... Done
Building dependency tree
Reading state information... Done
lib32readline5 is already the newest version.

The key is that it's the 32-bit libreadline file. The one the 64-bit OS looks to is the 64-bit readline file, which my version of ccxstream doesn't like.
