Error Building FBX-glTF Release

Building on Mac OSX, I've run into this error...

So, it looks like it couldn't find libcpprest...I updated it to look for 2.8, which is the one I had to install. Yet the problem above still existed. I removed the appendCode( const utility::char_t...) from .h and .cpp, which is probably not correct but it continued to build after that and now I'm getting these errors...

Any help with these build problems would be greatly appreciated.

I'm having the exact problem as @ryanbartley. So if anyone knows how to get through this we'll be both very pleased !! Here is the output of my make command after I updated the libcpprest path to 2.8 :

[frading]

Same problem for me too, unfortunately. Same output as @ryanbartley and @jazone. Would love to know the solution if there is one.

[Peters69]

Anybody found a solution for that issue?

[elifer5000]

Having the same problem here.

[ryanbartley]

Is this project closed? Would you be willing to take a PR replacing the enormous dependency of Casablanca AKA C++REST with a simple header only json engine?

[tparisi]

@cyrillef @ryanbartley that's a good idea -

[ryanbartley]

Preliminary work of swapping out the json engine can be found here. Tested and working on OSX. Need to update windows and linux, which I can do this week.

[vijayaprakash]

Hi,

I am extremely sorry for the delay. The build issue has been fixed in 'dev' branch.

Thanks, Vijaya Praaksh.
