Segmentation fault (OpenCL version) #6

Calimanov115 · 2021-01-03T12:18:55Z

Hello! I tried to build your program on Debian 10 and Manjaro 20.2 with Nvidia GPU and if i used default cpu based version of vanitygen-plusplus it's worked but when i want to use OpenCL version it just said me "Segmentation fault" on both OS after Compiling kernel process.

What's the arguments that you have specified?

Calimanov115 · 2021-01-03T13:37:18Z

I tried using arguments from the README file of this repository. The program is executed if no arguments are specified (only outputs instructions on how to use the program). But if you try to start generate private keys, an error will occur. For example, this happens even with such a simple command - ./oclvanitygen++ 1Love However, ./vanitygen++ 1Love works.

Same. Any help would be greatly appreciated.

Github "profanity" works great with GPU and ethminer GPU works great, but...

Ethminer can't work on mainnet because DAG is > 4096gb...profanity works great...

Recently, I fix a crash issue. May be the same issue you met here.

Suggest you try the latest code.
