Please I need help urgently :'(

So I tried to link an external C++ project against hxcpp generated static library, but I keep getting this error:

error: unknown type name 'co'
  HX_DECLARE_CLASS5(co,zenturi,mandolin,xnative,react,IJavascriptArray)

So it's been a while, but was wondering if this is still a problem. The first bit looks like a corrupt file - maybe a compilation was terminated. I would try removing the obj directory and trying again. The second part looks like a header file in missing or somehow not included, and I would beed to know more about the project setup.
