Cumulus Support

Hi,

While upgrading my Mono 4.6.2 installation to Mono 6.12.0.90, ahead of upgrading to the latest Cumulus MX release, I received the following lines during the installation:

Mono precompiling /usr/lib/mono/4.5/csc.exe for arm (LLVM disabled due to missing SSE4.1)...
Mono precompiling /usr/lib/mono/4.5/vbc.exe for arm (LLVM disabled due to missing SSE4.1)...
Mono precompiling /usr/lib/mono/4.5/VBCSCompiler.exe for arm (LLVM disabled due to missing SSE4.1)...
Mono precompiling /usr/lib/mono/4.5/Microsoft.CodeAnalysis.CSharp.dll for arm (LLVM disabled due to missing SSE4.1)...

Progress: [ 99%] [######################################################################################################..]

Additionally, the installation appears to have frozen as it has not progressed in over 15 minutes.

Do I need to be concerned about the missing SSE4.1 for Cumulus MX to be able to use Mono without issues? I am running Ubuntu 18.04.5 LTS (Bionic Beaver) (Kernel: Linux 4.19.62-sunxi) on an Orange PI Lite (Arm).

I followed the Mono installation instructions for Ubuntu 18.04 here: https://www.mono-project.com/download/s ... lin-ubuntu

Thanks

No concern, the ARM chips used on the rPi do not include the SSE4.1 feature - I assume it is the same for the Orange Pi.

The install compiles some of the executables which can take a while even on a pi 4 - I hate to think how long it would take on a pi zero!

Hi Mark,

Thanks for your helpful reply.

My SSH connection froze and could not be re-established and Cumulus stopped updating, so I think the' installation crashed my OPi Lite.

I rebooted and ran "sudo dpkg --configure -a" to repair the installation, which worked and didn't take very long. It seems to have completed the installation successfully without any errors and Cumulus is back up and running, so happy days. Thank you, again.
