Build errors: no matching function for calls pangolin::Widget and pangolin::Button

[franksvision]

Hello,

I was able to successfully compile prior to the widgets.cpp and widget.h update.
Below are the errors:

Are you certain that your files widgets.h and widgets.cpp are in synch? Do you have any local modifications? I can't fathem why the errors are referring to the Widget default constructor when on all those lines the correct constructor is being used.

Okay, for earlier versions of GCC it is necessary to be explicit about the template parameters when calling the base classes constructor.

Hello Steven,

All is well. I was able to compile. I created a new clone and it worked the
first time.

Thanks,

Frank
