example.pb.h：No such file or directory

Hi, is there anyone knows this issue,

when I make the libarcus on cygwin, it display below:

I'd expect example.pb.h to be created by Protobuf.

What happens when you manually call protoc --cpp_out /cygdrive/d/slicer_base_CuraEngine/libArcus-master/examples --proto_path=/cygdrive/d/slicer_base_CuraEngine/libArcus-master/examples /cygdrive/d/slicer_base_CuraEngine/libArcus-master/examples/example.proto? (You might have to replace protoc with a path to your protoc executable.)

Perhaps you have a buggy version of Protobuf?

Edit: Fixed python_out...

Note that you should use --cpp_out (or whatever it was that generates cpp files) since this is C++ code.

Yes, you're right, I use the latest version, so that's the problem, thanks
