Hi all,

I haven’t had time to look at VTK in weeks, and was sad to discover today several of my dashboards red since 2020-01-02:

[https://open.cdash.org/index.php?project=VTK&date=2020-01-02](https://open.cdash.org/index.php?project=VTK&date=2020-01-02)

```auto
In file included from /Users/builder/external/VTK/ThirdParty/jsoncpp/vtkjsoncpp/jsoncpp.cpp:76:
/Users/builder/external/VTK/ThirdParty/jsoncpp/vtkjsoncpp/json/json.h:1240:32: error: inline declaration of 'as<bool>' follows non-inline definition
template <> inline bool Value::as<bool>() const { return asBool(); }
                               ^

```

My guess would be it’s from this?

```auto

We had discussed this here: [https://gitlab.kitware.com/vtk/vtk/merge\_requests/6340#note\_675420](https://gitlab.kitware.com/vtk/vtk/merge_requests/6340#note_675420)

I’ll look at updating jsoncpp to include the upstream patch.
