TIOVX Compilation error

[ss13ms110]

Hello TI,

I am trying to compile the edgeai-tiovx-modules on BeagleBone-AI-64. However, with no success.

I keep getting TI/tivx.h not found.

debian@BeagleBone:/opt/edgeai-tiovx-modules/build$ sudo make -j2

Hi Shubham,

Can you please let me know which commit you are using?
This header file is now deprecated and removed in commit b5d47c3
Please try moving to this commit

Also please share the link to bbAI64 Image you are using, I can try this out at my end

I am using this BBAI64 image on my BBAI64 system.

I re-writing the image as I think I have been playing with it a lot and now its full of garbage.

Thank you

Hi @ss13ms110

This is because of a bug in the code, Not sure why this not throwing error always
May be its because of difference in gcc versions

static is missing in couple of test modules, will fix this and push a patch

Please fix locally at your end for now
