The directory war/WEB-INF/authkey contains the encryption keys used to encrypt/decrypt session cookies.

We could create this file each time we build the system. However that would result in each build invalidating any cookies used by the previous build. This would be a disaster for our production environment and an annoyance for developers working with the local development server.

Instead we keep a copy of the authkey keys in the file $HOME/.appinventor/authkey.zip. During the build process its contents are unzipped and placed in war/WEB-INF/authkey. If this file doesn’t exist an error (pointing to this file) is generated by the build system.

Follow the instructions in ...misc/docs/authkey.md. Basically you use
“ant makeauthkey” to create the key. You only need to do this once. The
key is stored in your home directory and used when you build MIT App
Inventor.

I've seen this happen on 64-bit installations where the 32-bit libraries are not present. If you are on a Debian-based system, you can install 32-bit compatibility libraries by doing sudo apt-get install ia32-libs

Depending on what distribution of Linux you are using your mileage may vary.

Take a look at our document on how to build MIT App Inventor from
sources (found at http://appinventor.mit.edu/appinventor-sources). In
particular look at:

https://docs.google.com/document/pub?id=1Xc9yt02x3BRoq5m1PJHBr81OOv69rEBy8LVG_84j9jc#h.pz6zzhs54gxj

which talks about making sure you have the 32 bit libraries needed to
run Google’s “aapt” program (which is the program it is complaining
about).
