How to start CumulusMX with dotnet in linux

[avvy65]

I have been using CumulusMX for a number of years on my Linux Mint computer. I use mono to start the program , ie 'sudo mono CumulusMX.exe'
Now as CumulusMX is updated to 4022 I want to know how to start it with dotnet8. I haven't updated to 4022 yet as I don't know how to run CumuslusMX

I don't see that on the link freddie provided, but it's "sudo dotnet CumulusMX.dll".

Yes, dll not exe. That is a first for me.

The need to use sudo depends on the ownership of the CMX drectory/file structure.
If that ownership is root and you are logged in as pi (or whatever owner you use for CMX) you will need to use sudo.
If that ownership is pi and you are logged in as pi (or whatever owner you use for CMX) you don't need sudo.

It is advised not to install CMX as root.

It seems like a lot of work to use 4022 version, from the link given.

What is the conversion program which converts the said files from v3 to v4
How can you keep? v3 to be converted to v4. I know about copying the said files to a safe place then copying them back to v4

The software to migrate the data files to V4 is mentionedin the link Freddie gave.

I would recomment studying that link fully BEFORE migrating.

FWIW you can run V3 and V4 on the same machine so once you have copied and migrated your data files you can continue to log data with your working V3 set-up and if the V4 doesn't suit then just carry on with V3 - no loss of data. DO NOT install CMX V4 in the same directory as V3!!

I migrated my three V3 systems to V4 and everything went well and I am very pleased with V4 from a performance point of view.

Ok thanks , but I hit my first problem
Using Migratedata3to4 returns
MuigrateData3to4: command not found.

I installed 4022 to a new CumulusMX folder, then copied the said file fro v3 to v4. I also renamed the v3 data folder to datav3 a per the instructions.
The one thing I didn't do is change the path to the v4 fiolder.
Also when I ran the command : sudo ln -s /usr/share/dotnet/dotnet /usr/bin/dotnet
It returned failed to create a smbolic link '/usr/bin/dotnet': file already exists. I actually installed dotnet from software mamanger , rather than from the cmd line from the link. This was because of an error I encountered to do with one of the library files.

thanks

Ok thanks , but I hit my first problem

What does the dotnet --info command show (screenshot please)?
What does ls -al Migr* in the CumulusMX directory show (screenshot please)?
Do you execute MigrateData3to4 in the CumulusMX directory?
Hoe do you startup the conversion ( the MigrateData3to4 commandline)?

[avvy65]

As requested

That was running the command "dotnet MigrateData3to4.dll"? (note capital D).

SORRY: Cross posted!

[philpugh]

dotnet appears to be installed ok but the first command Hans gave had a * in it the command should look like

philpi5:~/WS68 $ ls -al Migr*
-rw-r--r-- 1 phil phil 32256 May 13 11:49 MigrateData3to4.dll
-rw-r--r-- 1 phil phil 143360 May 13 11:49 MigrateData3to4.exe
-rw-r--r-- 1 phil phil 340 May 13 11:49 MigrateData3to4.runtimeconfig.json
phil@philpi5:~/WS68 $

I have CMX under the WS68 directory on my Rpi. For your system you would run it starting with…

dotnet MigrateData3to4.dll

The full command is in the instructions at the top of the V4 section of this board.

See post viewtopic.php?t=22051

Forgot to mention. Take a copy of all your data files BEFORE you start this - just in case!

[avvy65]

Thanks.
I ran MigrateData3to4.dll this time, I forgot about .dll before, doh!
The data files were then converted to version 4.

So now they are converted, how do I actually start version 4 . Do I have to run CumulusMX as a service or can it be run any other way. I am the only person who runs and sees the data

[mcrossley]

At first you could run it interactively...

Code: Select all

dotnet CumulusMX.dll

Once you are happy it is working OK, install it as a service. Running it interactively means it will stop when you logout.
