Updation not working

The program is working fine but it is always "Generating a new counter address" that is, it is never updating the already existing count.

Lecture 2

I don't see lecture 2, from the first two videos in the playlist

Thanks for your Solana Bootcamp video and a question

Sorry for the direct approach, and I know this is a long shot, but desperate times, desperate measures.

In your video, you talked about cargo build-bpf and it seems you deeply understand all those things.

My problem is when trying to add the h3ron crate to the example-helloworld solana program.
You don't have to write any code, just adding the dependency will have the helloworld fail at build time.

I created this issue: solana-labs/solana#22725
To get there I tried many things with the h3ron creator here: nmandery/h3ron#30

Unfortunately, I am not going to be able to update the build.rs myself.

I don't find it normal that solana would not support adding a C-binding rust library to his dependencies.

Sorry for the direct approach. Can you please help me unlock the situation, please?
