Can someone post a working environment (OS, package, host compiler version) that can make this work?

I'm also seeing an error when trying build on ubuntu 18.04. @dragonware-com did you find anything?

I have the same problem on ubuntu 18.04.
After change to use gcc/gcc++ 5.5.0 , everything is okay.

@rockman182 what do you mean by changing gcc/gcc++ 5.5.0 ... I also have the same problem

[rockman182]

@suhasskrishanmurthy ubuntu 18.04 build in gcc is 7.x.x , you need to install an older gcc version.
