Which nodejs version was tested with this package?

[Slach]

I try nodejs versions 5,6,8,10,11
and everywhere node-gyp rebuild was failed with following errors

is only one way to get sample CPU profile is using perf-map-agent + perf ?

This package is supported with node 0.10

To support 4,6,8 or 10 you would have to update

https://github.com/uber-node/node-flame/blob/master/lib/heap-reader.js

This class knows the internal memory layout of v8 and is able to turn a C stacktrace into a javascript function name. Namely by https://github.com/uber-node/node-flame/blob/master/lib/heap-reader.js#L372
