ZCU104 OpticalFlow: Can not build gstdemo

[speedup]

Hello, 

I am doing the Opticalflow tutorial from https://github.com/Xilinx/reVISION-Getting-Started-Guide/blob/master/Docs/tool-flow-tutorials.md , but at the step "Build gstdemo project" the system is not working with me anymore. 

I am supposed to build the project, but it is not possible (see grey hammer in picture).  

What could be the problem? The opticalflow project build perfectly fine. Photo from the tutorial is attached below. 

I am running it on a windows10 computer. 

Thanks in advance

Hi @speedup 

Looks like the gstdemo project is present in the folder but it is not active inside the workspace.

Please try to open the project in workspace

HI @speedup 

Is your issue resolved?

I uninstalled everything and tried to follow the ReVision guide again and suddenly it all worked out. 

Thanks for the help
