You are missing the “grin-miner.toml” file in your grin-miner binaries directory.

Copy the file from ~/grin-miner$ to ~/grin-miner/target/debug$ directory

Done, thanks!
but now it gets killed a second or two after running grin-miner from the debug dir
the ui remains on the screen, but i can see the cursor line come back and above it and to the right poking through the ui i can see the word ‘killed’
not sure what’s rthe problem

Try to compile a new copy from github.
There is updates…

still not working, perhaps it’s crashing because system only has 4gb ram and old cpu?

Check your grin-miner.log for possible more diagnostics about the crash.

Good advice tromp.
For active monitoring of logfile use “tail -f grin-miner.log”

When i start “./grin-miner --floonet” the miner app uses 3,7 GB of memory.
Your problem is your memory, you need more.
The second line of your fault message is “Out of memory”

I’m CPU mining…
I don’t have any functional GPU card for mining… ☹

All i have are a bunch of 4gb amd’s doing Monero, i was hoping to reassign a couple for Grin. unfortunately they don’t have enough memory to participate, and no miner support yet.
So against my better judgement i went out and bought a 2080 this evening. This will be the last graphics card I ever buy, i swear!

ok success…
problem was i had no swap disk, (for some misguided reason, i have not been using swap partitions hoping to save my cheapo ssd’s from abuse)
so i made a swap file and it started right up
i have mined a handful of different coins / algorithms and this is the first time 4gb was not enough
Thanks everyone, I am going to stare at this for a while and see if i can make heads or tails of all these systems…

So did you successfully mine at 4GB?
