Charlock_holmes could not be installed.
Installing charlock_holmes 0.7.6 with native extensions
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

/usr/include/unicode/umachine.h:340:13: error: ‘char16_t’ does not name a type
I had to execute sudo -u git -H make CXXFLAGS="-std=c++11 -fPIC"
to get the gitaly installation done. The same for gitlab itself. I had to set sudo -u git -H bundle config build.charlock_holmes --with-cxxflags="-std=c++11 -fPIC"
