I had several errors when I first tried to install CQRLOG. First there was the error with apparmor. The installation script with CQRLOG 1.9.0-5 did not add the correct line into /etc/apparmor.d/usr.bin.mysqld
There was also an error related to the MySQL library. This was partly due to an incompatibility with the MySQL client in CQRLOG and the version of MySQL server installed.
Installing CQRLOG 2.0.5-1 fixed this issue.
