catkin_make failed after jetson-inference update

Could not build ros package after installing latest version of jetson-inference

Seems like signature of detectNet::Detect() changed after this commit of jetson-inference but this package is using the old signature.
Is there a tag/commit of jetson-inference for which this package works?

Hi @aparwal, sorry - looks like I need to update this ROS node.

For now you should be able to use the L4T-R32.1 tag of jetson-inference, that was captured before these changes were merged into master.

[aparwal]

Thanks, the node works for that tag.

I am sorry, but I am relatively new to GitHub, and have been having difficulty understanding what you mean by tag? Is this the same as branch?

I ran into the same issue last night, and am wondering if I need to checkout the branch L4T-R32.1, and follow the build steps again (for jetson-inference) to get this node to work?

Thanks for your help @dusty-nv @aparwal !

Found the same problem, but I will wait for the update :D
Thanks

Looking at Detect method in "detectNet.h" and the same Detect method used in "node_detectnet.cpp", jetson-inference repo doesn't seems aligned with the ros_deep_learninig repo.
I'm waiting for the update too!! ;)

Hello kmartin .... just used your update and all went well with build, waiting on a camera to move further. Thanks for the update.

The ros_deep_learning repo has now been updated for JetPack 4.2 and to build against jetson-inference master. Let me know if you have any more problems building it.
