I know this thread is old, but if anyone is still trying to get past the error:
"./reaper: error while loading shared libraries: libblkmaker-0.1.so.0: cannot open shared object file: No such file or directory"
After finalizing with "sudo make install" on libblkmaker library, run the "ldconfig" command as root while still in the directory.
That should fix it.
How does it stand up against other XPM gpu miners?
I actually only started playing around with this one yesterday. I haven't tried any of the others, yet.
Just going to let it run for a few days. Depending on how that goes, I might start checking out the others.
