scripts/start-server.sh missing? about gr-bokehgui

[kkpatel1]

Thanks.
I just pushed a commit that solves the issue. Probably when I tried to re-install the module for testing, the start-server.sh never got deleted and hence, all of my examples still worked!

Let me know if the updates work.

Is node.js required to use these blocks? I can start the flowgraph, but when I go to http://localhost:5006/bokehgui I get the error (in my console): RuntimeError: node.js is needed to allow compilation of custom models

EDIT- I installed node.js just to see if it fixed it, and now I get the following error when running any of the examples and then going to http://localhost:5006/bokehgui

[kkpatel1]

Yes. That is because the Waterfall plot in this module is a "custom models" (not provided by Bokeh). Thanks for the reminder. I will add it in CMake and README.

I guess I will create a virtual machine to re-setup the module.

[777arc]

I just updated the previous comment with my error after installing node.js.

[kkpatel1]

@777arc Please use NodeJS v6.6 or above. The default Ubuntu package manager installs v4.8.

Updated the details on README. Thank you.

[MattEttus]

It looks like start-server.sh is still missing. Are you sure that commit got pushed?

[kkpatel1]

@MattEttus It's fine without that. I changed the function itself at that time.

For now, I am closing this issue. Kindly re-check and if you find the issue still there, I will re-open the issue.

Thanks.
