Yade

Gts issue building GUI on a Cray HPC

Asked by Gary Pekmezi

Hello,

As mentioned in my previous question [1] related to my ongoing quest to build the latest Yade with GUI on this system, I was able to build the GUI successfully. However, upon attempting to run it, I get the following error

Welcome to Yade 2017-12-06.git-890f2c2
TCP python prompt on localhost:9000, auth cookie `ecssdu'
XMLRPC info provider on http://localhost:21000

This seems like some sort of linker problem, but I don't yet understand enough about building Yade to track it down. Any assistance would be greatly appreciated.

Thanks,
Gary

I managed to resolve this problem. As suspected, it was a linker issue. The issue was that pygts did not know where to look for my local gts build. This was resolved by adding the gts/lib path to $LD_LIBRARY_PATH.
