Please describe your question

Ask about Holoscan SDK features or best practices. For example, "Does Holoscan SDK support v4l2 compatible cameras?" This is a question and not a bug report since i am not sure if i just did a mistake or it is real issue. i followed the steps for building Holoscan-SDK. Due to some errors i changed the html from 2.0 to 1.1.

Now i get ninja: error: 'lib/libajantv2d.a', needed by 'lib/libholoscan_op_aja.so.2.3.0', missing and no known rule to make it whenever i do ./build run --target debug. I am not sure if those two problems are related and i also don't know how to fully restart. As yo

Please specify what Holoscan SDK version you are using

latest

Please add any details about your platform or use case

I am using a Linux (Ubuntu 22.04.4) Cuda 12.2

I am not that experienced so i would really appreciate your help and thoughts on my Problem.

Hi @sese1815 , thank you for the report. The issue you've observed is a known issue in Holoscan SDK 2.3.0 when building in Debug mode, and is scheduled for resolution in Holoscan SDK v2.4.0.

As a workaround, you can either:

Build in Release mode: ./run build --target release
Manually set the ajantv2 build type to Debug at https://github.com/nvidia-holoscan/holoscan-sdk/blob/main/cmake/deps/ajantv2_rapids.cmake#L37 and build in Debug mode: ./run build --target debug

Fixed in Holoscan SDK v2.4.0.
