Niryo One - MATLA interface

Dear Matlab Expert,

I am trying to connect Niryo one robot with Matlab R2020b on Windows10. In doing so, I receive the following error message.

folderpath = "C:\Users\Afsoon\Downloads\Applications\niryo_one_ros-master";

>> rosgenmsg(folderpath)

I have installed CMake, Visual Studio 2019, and Python 2.7. Also, CMake is available on the system PATH environment variable. I appreciate your advice on this issue!

Thanks,

Hello Afsoon,

Can you try running this code in MATLAB:

!cmake --version

If you see any warning messages about libcurl or libstdc++, see this answer for suggestions and workarounds that users have found.

Dear Cam,

Thanks for the reply.

>>!cmake --version

cmake version 3.20.2

CMake suite maintained and supported by Kitware (kitware.com/cmake)

Then I run the code:

>>rosgenmsg(folderpath)

No C++ compiler selected for ROS build. To choose a compiler, run 'mex -setup cpp'.

Error in ros.internal.CatkinBuilder (line 24)

[e-mail](varargin{:});

Error in rosgenmsg (line 223)

builder = ros.internal.CatkinBuilder(genDir, pkgInfos{iPkg});

Then, I run teh code:

>>mex -setup cpp

MEX configured to use 'MinGW64 Compiler (C++)' for C++ language compilation.

What compiler do you suggest?

Thanks so much,

R2020b requires Visual Studio 2017 as the only supported compiler for Windows.

If you upgrade to R2021a, you can use Visual Studio 2017 or 2019 on Windows.

The use of Visual Studio for Windows is unfortunately a ROS requirement, so MinGW will not work.

Dear Cam,

Thanks so much for the reply. Yes, the problem is solved by using visual studio 2017 instead of the 2019-version.

Best of luck,
