RUXX

hello everyone, I am trying to build QGC custom source code version 4.2 using Qt 5.15 MSVC2019 64 bit. iam getting few errors which im unable to solve after many tries. if someone can guide me on how to solve the errors it will be really very very helpful. im really trying very hard to understand where im going wrong and solve the issue but unable to resolve it. I have attached the image below.

I don't see what Qt has to do here with the problem or how it could be fixed here. You should ask the mavlink devs on why this mavlink type is not defined. Maybe your mavlink libs are out of date.

epoli

@SGaist Apologies, that page doesn't exist anymore. you can also use chatgpt or few other ai tools to solve the error.

epoli

@RUXX if you remember how you did it please let us know, couldnt find a solution up to now

@epoli The error can occur if you haven't included the header file that declares the identifier. Make sure the file that contains the declaration for the identifier is included in every source file that uses it.

epoli

thank you for your help. it is working now.
for anyone who may face the same error , you have to include the header file which is #include "../qgroundcontrol/libs/mavlink/include/mavlink/v2.0/ardupilotmega/mavlink_msg_rangefinder.h"
in you vehicle.cc file .
