I recently downloaded AOCL-pro-126.96.36.199-linux.tar and ran the install script. According to the instructions here, there should have been an eclipse plugin file in $INTELFPGAOCLSDKROOT/eclipse-pug-in. But instead, I found there was another similarly named env var defined (INTELOPENCLSDKROOT) pointing to /opt/intel/system_studio_2019/opencl/SDK, where I did find that plugin.
I followed the directions in the programming guide (link above) and placed the CodeBuilder_6.4.0.jar in my eclipse/dropins folder. After a restart of eclipse, I don't see any reference to it in the Windows->Preferences, and I don't see any evidence that it was picked up.
I'm running Eclipse 4.13 on Ubuntu 16.04.
One data point: if I run eclipse on the command line with "-console" option, and then do "lb" (list bundles), I see
595|Installed | 4|CodeBuilder (6.4.0)|6.4.0
So something is happening. What am I supposed to see or open to access the functionality of that plugin?
