tangram-es: Raspberry Pi 3 Model B / Raspbian Make Failed

Hi Devs,

Over the weekend, I have been trying to install tangram-es on a Raspberry Pi 3Model B running the latest Raspbian image - with no joy. It all looks good and then fails at the final make stages.

I have tried following the tool chains here: https://github.com/tangrams/tangram-es and here: https://www.raspberrypi.org/blog/tangram-an-open-source-map-rendering-library/

And combinations of the two. I have also searched through the issues on github.com (and google) and tried various fixes but it keeps failing at the same point with the same errors. I have posted the output below as well as some useful debug info regarding C++ compiler and make versions etc.

Any pointers would be greatly appreciated!

Sorry about the long post - figured you would need the debug info …

Many Thanks,

Wardo.
