Arithmetic exception running C++ vio_jsonl with OAK-D S2 #31

Closed RR-BenSteer closed 2 years ago

RR-BenSteer commented 2 years ago

Hello,

I've built the C++ OAK-D examples by linking to the libs from the Linux_Ubuntu_x86-64 release (spectacularAI_depthaiPlugin_cpp_non-commercial1.1.1.tar.gz), but I've had the following issue when running the vio_jsonl_ example:

Stack trace (most recent call last):

Floating point exception (Integer divide by zero [0x7f3cd45796f2])
Floating point exception (core dumped)

I'm using Ubuntu 18.04.6 LTS and my architecture is indeed x86_64. I am using an OAK-D S2 and I've tried both the main branch and the oak-d-s2 branch of sdk-examples. I have the depthai-core libraries installed on my system already (built as shared objects).

Strangely, _viojsonl runs fine with the OAK-D S2 when I use the binary included with the Linux_Ubuntu_x86-64 release.

Any help with this would be appreciated, as we are trying out Spectacular AI for potential use in a real-time 3D reconstruction project :)

Thank you for the bug report! We believe we've identified the cause and are aiming it to be fixed in the next release which is coming out next week

Great, thanks for letting me know!

The root cause for this was likely that the previous version was using v2.15.3 depthai-core while the docs instructed to use v2.16.0. We've now released 1.2.0 version of our SDK that uses v2.16.0. Please let me know if this fixes your issues: https://github.com/SpectacularAI/sdk/releases/tag/v1.2.0

Hi, I tried building the OAK-D sdk example with the v.1.2.0 release and was able to run vio_jsonl successfully! I made sure depthai-core was v2.16.0. Thanks for your help.
