# Trouble when compiling from the github repository

Dear community,

I'm trying to install the latest release (from the github page) of cadabra2, but I got some errors when compiling

This is part of the make process (the previous cmake .. does Ok)

Compilation error

I thought it could be harmless, but at last the sudo make install returned

Installation error

Q: Any ideas?

For the 2nd issue, read the message: you need to run make deduplicate (possibly with sudo) to remove the manual pages installed in an old deprecated location, and then make install will work again.
Sorry for the damn question! I didn't understood the "make deduplicate" was a command line. Thank you so much!
