Illegal Instruction (core dumped) - Ubuntu

Tech Support
1

Hi - I’m on ubuntu and attempting to get it running. I have tried building the release (following the instructions left here, and grin compiles, I can init and listen to the wallet, but when both building the grin-miner through the instructions and trying to use the prebuilt miner found here, the program crashes with the illegal instruction (core dumped) message. That happens on the built version regardless of if I tried to build the cuda plugins for video card mining, or if I just build with the default cargo.toml file for cpu mining.

the log doesn’t even seem to point to an error:

Does anyone have any hints, tips suggestions on how I can get this thing working on ubuntu or what I’m doing wrong? I’m running rustc 1.31.1 when building the client with cargo.

what gpu are you running?
