# Got Errors?

Are you getting LaTeX errors when compiling the Open Logic Project files?  If you get this one:

LaTeX Error: \memendofchapterhook undefined.

it means you have an old version of the memoir class installed. Get a new version from CTAN, or update your TeXLive or MacTeX distributions.

If you get another one, make sure you have the most up-to-date version of OLP installed.  If it persists, please file an issue on GitHub, and attach the .log file of the file you’re trying to compile.
