protobuf messages are generated but could not be found during build configuration #76

Closed PennyXQZ closed 1 year ago

PennyXQZ commented 1 year ago

During the build progress,

I can see that the files messages.pb.cc and messages.pb.h files are build in path: build/include/model path/*,

and file messages_pb2.py is built in path: contrib/opengym/model/ns3gym/ns3gym/model/*.

However, I meet the error during the build command that:

`[ 27%] Running cpp protocol buffer compiler on model/messages.proto Scanning dependencies of target libopengym-obj

I solved this problem by modifying: 27 | #include "messages.pb.h" to 27 | #include "model/messages.pb.h" in container.cc and the problem is solved. Thanks!
