I’m just starting in the Jetson development process. I have a TX2, and have loaded it up with JetPack using an x86 Ubuntu host. Now if I want to run and profile cuda code on the TX2, it sounds like it’s easier to avoid cross compilation and go with the sync projects approach.
So i run up my nsight-eclipse on he host, and attempt the directions in https://devblogs.nvidia.com/remote-application-development-nvidia-nsight-eclipse-edition/.
I set up git on both host and target, I add a new target system (the TX2) without difficulty, and the comms look clean. I set up a host project using the cuda sample ‘simulations/particle’. I then go to run it as remote c++ app, which I was (maybe naively) expecting to
- copy over the relevant c++/.cu files to the tx2
- compile on the tx2
- run/debug on the tx2.
Sadly no:

so it goes looking for the exe (particle) to run, but there’s nothing there.
So how come we’re building locally, rather than on the Jetson?
What am I setting up wrongly?
Any hints gratefully accepted!
