Boost fails to download for configure/build

[hlfritz]

Describe the bug
I am trying to build for cuda 11.2 on ubuntu 18.04. everything goes swimingly until i use cmake to configure the build (obviously i do not get far). it fails to find the url for the Boost package.

To Reproduce
Steps to reproduce the behavior:

1. follow build instruction to the point of cmake .. to configure the build.
2. errors on

Expected behavior
that the Boost file downloads and the configure process continues.

Environment (please complete the following information):

• Operating System: Ubuntu 18.04
• Hardware A100
• Ethminer Version 0.19.0
• Ethminer options used : cannot even get there yet.

Additional context
Help! are there alternatives to the auto download?

Same setup , same cuda and A100s ...and exactly same error

Thx for doing the research, yes, got it to compile. maybe the devs will update the source package.

did you have any luck with your a100's? i get:

CUDA Error : system not yet initialized
Error: No usable mining devices found

even though nvidia-smi sees all the gpu's.

PR #2284 resolves the Boost issue. Use that branch/fork until it gets merged

Also seeing this. Trying @jimmystewpot fork for now.
