toml module is missing about 4dface HOT 2 CLOSED

I think you may need to update eos or update its submodules, i.e., in your eos directory:

$ git checkout master
$ git pull
$ git submodule update --init --recursive

Possibly you also need to add the toml11 directory to 4dface's include paths. Note that 4dface uses quite an old eos version (0.9.1) - I've never had the time to update that submodule and adjust the 4dface code accordingly. But it would be trivial.
If you want to do any serious work or evaluation of eos, I strongly suggest you use the latest eos version though from github.com/patrikhuber/eos.

After updated all the external libraries, issue resolved.
