I tried to use Protocol Buffers in ROS Indigo, look in the link CPP source code problems, at compile time, it raises the following error:

I doubt CMakeLists. TXT file, what did I miss?
CodePudding user response:
Protobuf version does not match, I installed the Protobuf 3 from source, however, ROS Indigo used internally Protobuf 2.
As a solution, I deleted the Protobuf 3, and then install it in my local projects,
CodePudding user response:
Can also be CMakelists. TXT in the mandatory protobuf3 specified path
