Issue with version DOCA when compile Sample

Infrastructure & Networking BlueField
1

Hi there,

I’m encountering an issue when attempting to compile a sample project. The linker is attempting to link to version 22 and 23 simultaneously.

I’m trying to remove the files associated with version 22, but the application is unable to compile.

The project is using DOCA 3.1 and BF-2.
