I have this same error as well when connecting Segway using USB mode. On the other hand, if I use the serial mode, I got this error.....

I can guarantee that the "libsegwayrmp" package was compiled with "serial" as it says libewayrmp serial supported during its compilation. This might be a problem of CMakeList.

@dikke these errors seem to be different.

As for your error, if you're sure you built with Serial support then you might be using a different instance of the headers? The availability of the Serial support is baked in at CMake time if I remember correctly.

I don't have a segway to test with, so the most I can suggest is that you rebuild it and make sure it has Serial support enabled and that it finds the serial library it needs to build in serial support.

Thank you for your reply. I have further tried with the segwayrmp_gui. This is a binary comes from "libsegwayrmp" package. Please see the result below.

First Photo uses serial connection, no errors.

s1

Second photo uses USB connection, there is error.......

s2

The problem is that, I still can't get the serial version working with "segwayrmp" package. There must be dependency issue during the compilation. The problem, is perhaps, found in here: https://github.com/segwayrmp/libsegwayrmp/blob/master/cmake/segwayrmp_serial.cmake

That is strange. I agree that the only thing that could really be happening is that the segwayrmp package is finding and linking against the wrong libsegwayrmp library.
