Failure in compiling examples/calibration/main.cpp

[Jayden9912]

Hi. Thanks in advance for spending time reading my issue.

Could anyone help me on this error?

The OS system using is Ubuntu 16, and the SDK is built from source. I rename the main.cpp to camera_calibration.cpp and put it to the root of Azure-Kinect-Sensor-SDK. The command use is cd to the root of Azure-Kinect-Sensor-SDK

g++ -Iinclude -std=c++11 camera_calibration.cpp

Here is the error:

The file structure Azure-Kinect-Sensor-SDK/include/k4a/k4a.h Azure-Kinect-Sensor-SDK/include/k4a/k4a.hpp Azure-Kinect-Sensor-SDK/include/k4a/k4a_export.h Azure-Kinect-Sensor-SDK/include/k4a/k4atypes.h Azure-Kinect-Sensor-SDK/include/k4a/k4aversion.h Azure-Kinect-Sensor-SDK/include/k4a/k4aversion.h.in

The following is how I build this SDK.

git clone https://github.com/microsoft/Azure-Kinect-Sensor-SDK.git
cd Azure-Kinect-Sensor-SDK
mkdir build && cd build
cmake .. -GNinja
Ninja

Hi, any update on this?

Hi, @Jayden9912

What you are trying to do? could you please share your camera_calibration.cpp?

Hi, @fkavache .

I am trying to compile this cpp file only. My camera_calibration.cpp is the same as the one in this repo. https://github.com/microsoft/Azure-Kinect-Sensor-SDK/tree/develop/examples/calibration

@Jayden9912

You need to link k4a, this line, from cmake, is responsible for linking k4a to that example.

@fkavache I am using Ubuntu 16 and I only build from source the whole repo but I didn't install it into system directory. If I use cmake, it fails. Is there any way to link the library to g++? I am more proficient in Python so I may need guidance in compiling this code. Thanks in advance for any guidance provided.

Could you please screen what the cmake tells you when you try this?

git clone https://github.com/microsoft/Azure-Kinect-Sensor-SDK.git
cd Azure-Kinect-Sensor-SDK
mkdir build && cd build
cmake .. -GNinja
Ninja

I also face the same problem. Is there any solution for this? As @fkavache said, this is what I've got from run ninja and this is what's inside my cmakelist.txt but still getting the result as this. I think the link directory is already right. Am I missing something?
