Errors while compiling Monero on openSUSE

Question

I'm trying to compile latest version of Monero On openSUSE Leap, but it throws an error:

It seems to be related to src/common/thread_group.cpp. What should I do?

Update:

I'm able to build the official stable release (v 0.10.0) from the source. So the problem must be related to newer commits.

That is indeed the case. This pull request should resolve the issue
