Do not allow sending files (in the end it is good), I leave the file in the cloud here; I hope it serves what you want to look at.

Both things confirmed, I have the output here I will try to send it to you by direct message.
The tests were against the testnet, so I am not struggling with the current difficulty of the chain.

Ok, we have this controlled, yes I confirm in advance that we have mined it in the past with the LitecoinCash cpuminer-multi alone;
Anyway, I execute an iteration with the flags that you indicate me;
I save the result to you in a plain text file and send it to you.

Thanks for the explanation of the Getwork and GBT, it makes everything very clear

I can try Ring (because it's what I've already installed on my computers) and the one I'm most familiar with (also the one that knocks on the door); but I guess the other currencies (CPU only, which is what I can help with) shouldn't be much different;
- put the wallet down
- sync (which is the heaviest, but a pruning = 100 MB)
- request a legacy address
- put a mine against your node

I don't understand very well about 'getwork'; if i use it myself or if the blockchain responds to that command? if it is the latter, I don't see that command between rpc commands; maybe my other colleagues know more about it

Let's say I'm new, among the RPC commands, mining ... but I dock quickly, if you tell me what to do exactly or where to read I can keep up with you.

I can help you with testing and compiling on Linux computers. 

Copying text from a command window in Windows is:
- In the command window, right-click
- Use the 'mark' option
- (Optional) Scroll in the window with the right sidebar, from where you want to copy
- Press the left mouse button (the marker is shown here) and drag/slide the score for everything you want to copy
- Once everything is marked, press the right mouse button; and the selection remains on the clipboard to be copied where needed (Ctrl + V)

Cheers 

In my case, I have tested it on Linux and I have problems, even with one of the two you mention that works (AES-SSE42). I wanted to leave you an attachment with the screen outputs, but I see can't; You tell me what options you need me to put in to help you improve the problem.
