Hello all,

I am getting a very convoluted error message while building grin as per this tutorial: [https://medium.com/@blade.doyle/gpu-mining-on-mwgrinpool-com-how-to-72970e550a27](https://medium.com/@blade.doyle/gpu-mining-on-mwgrinpool-com-how-to-72970e550a27)

Here is the pastebin of the log: [https://pastebin.com/vdy5h627](https://pastebin.com/vdy5h627)

**I think this is the most important line:**

> [20%] Built target cuckatoo\_mean\_cpu\_avx2\_19
> 
> Makefile:83: recipe for target ‘all’ failed

I do not qwant to build the CPU miner, I would be happy with the mean GPU miner alone. What can I do ?

What version of the gcc are you using? I had to switch mine to v 6 from v 7. Check out [https://github.com/mimblewimble/grin-miner/issues/92](https://github.com/mimblewimble/grin-miner/issues/92)

Maybe that will help
