Linux Build Error "unknown type name SC_HANDLE" on Ubuntu 20.04

[cniweb]

On a Ubuntu 20.04 system:

gcc --version
gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0

I get an error:

What can I do against it?

I get the same on 20.10. Not sure what the issue is

I was able to compile past that by editing the MSR section of miner.h and rem'd out: static SC_HANDLE hManager; static SC_HANDLE hService; static HANDLE hDriver;

These appear to be Windows compiler settings for service manager. Not sure why the makefile is not taking care of this.

Still chasing Alice... Looks like I'm just reverting to the prior commit: https://github.com/LUX-Core/rx2-cpuminer/tree/97b30645aa6efc3e092faee7ac3e9c14c82babe5

I recommend pulling the prior commit. I was able to rem lines 47 and 48 in rx2_algo.cpp, as well as all MSR references in cpu-miner.c. It built and ran, will test with a pool/wallet, but it breaks the intent for cross platform compiling.

these "HANDLE" are for windows only, forgot to put an exception. Will correct that. For the time being, for linux use the previous release and to use MSR you just need to set parameter in bash file
