Compilation failure

[Baughn]

On the newest Ubuntu, it appears there's some compiler flag missing:

Thanks, I will try and reproduce.

From the error message, it may be that glog.cc.o is getting compiled without -fPIC. That sounds like a problem in the autoconf/configure script. If you want to play with it, you can try to run ./configure && make manually in that directory to see if it still gives the error.

I can reproduce the failure on Ubuntu 14.10 as well.

Running ./configure && make in the glog submodule doesn't yield the error, but running the repobuild make does.
