I wanted to upgrade from stable to master branch, but it’s not possible to generate a new project using Poco::FastMutex for me. With the release version 0.9.8 it’s working.
... Poco::FastMutex ourMutex; ...
I tried the generator-vs the release and nightly build (v20170714) version, but the lib poco was not included correctly.
The download script worked properly, so the lib is available.
