Could you please explain the right way to install it?
Many thanks in advance.
the issue has been caused by the old version 1.62.0 of libboost-system. Our newly deployed Mervis packages 2.2.x.x are based on the Debian Buster distro where the version 1.67.0 of the package is used. It should be fixed in the dependency list now.
Can you please do apt update and try to install the package again?
Many thanks @martin_triska: installation is now successful and I could get the solution working.
However, the installer does not create the service file:
root@M505-sn69:/opt/unipi/tools# systemctl enable sscp-sql-daemon Failed to enable unit: Unit file sscp-sql-daemon.service does not exist. root@M505-sn69:/opt/unipi/tools# systemctl start sscp-sql-daemon Failed to start sscp-sql-daemon.service: Unit sscp-sql-daemon.service not found.
the service is named after the package: sscp-sql-bridge
Yes, many thanks!
I suggest you to correct service enable documentation on https://kb.unipi.technology/en:sw:01-mervis:08-sscp-bridge
Thank you @pascal37, I fixed it!
Dear Unipi support team,
Is there a way to make the SSCP to SQL Bridge more robust, for example, so that it is not necessary to restart it manually after every solution deployment or PLC restart?
Many thanks in advance and kind regards.
