Erros when making the project

[Salman Husain]

Hi,

I think I am facing errors building the project when SWIG is enabled. I wasn't having this when I built the project with Python not enabled. Note, the prject was building just fine till ~last week with Python adnSwig etc.. Here is the error message,

[ 99%] Built target demo_ROBOT_Industrial

You need to clean the solution and rebuild.  This happens sometimes with SWIG-generated stuff when there’s an API change (which happened a day or two ago with the function GetSimulationRTF).

Hi Radu,

Thanks for the quick follow up, 

I appreciate your patience.

However, now I am having some issues with the ROS2 modules :(.

I am cloned the repo from scratch and built it in a clean new folder. 

Cheers,

Sal

Note:  Before the errors I see this output,

Hi Radu,

All good now. I followed through the parsers module installation again. Everything works.

Hi Sal,

 

Glad to hear you got it working.  In general, “make clean; make” is the software equivalent of the “turn it off and then on again” for hardware 😊. Especially when there were API changes.

 

Best,
Radu
