I move the project from computer A to computer B, and don't rebuild getreamer-superficial, I think it will work well as other node modules, but it is not

Two computer are all ARM arch, and chip is small


  return process.dlopen(module, path._makeLong(filename));

as you know, node-gstreamer-superficial dynamically links against libgstreamer (in fact, against a number of different gstreamer-related libs). The node module you build on one host is not transferable to another- unless the environment is exactly the same there considering all the required libs. I suspect some library is missing on your "computer B".

To see which libs a binary is linked against, you can use ldd:

# ldd build/Release/gstreamer-superficial.node

@aokihu, any news about this? Did you get it to work? It'd be great if you can leave your solution for others to find here.
