build glog/press failed

[ericuni]

I'm trying build in a docker environment and I have installed libunwind8 and libunwind-dev.

glog(master ✗) pwd

Hopefully #15 can fix this.

However, I think libunwind8 implies Ubuntu (or Debian), on which there are still some other issues to be fixed:

• An undefined reference to pthread_once, even if we've already linked against pthread.
• link_all_symbols does not work.

We're still working on these issues.

Thanks, it worked now. I'am using ubuntu:20.04 as the docker base image.
