OS: Raspberry Pi Bookworm (32 Bit)

Tutorial Followed: [[Object and Animal Recognition With Raspberry Pi and OpenCV - Tutorial Australia](https://core-electronics.com.au/guides/object-identify-raspberry-pi/#Set)]([Object and Animal Recognition With Raspberry Pi and OpenCV - Tutorial Australia](https://core-electronics.com.au/guides/object-identify-raspberry-pi/)

Target: To detect birds using OpenCV

Library: All libraries installed except libpng12-dev, replaced by other latest one.

Problem faced after providing “make -j $(nproc)” command. Everything followed to the point.

Last Output: [36%] Linking CXX shared library …/…/lib/libopencv\_tracking.so [36%] Built target opencv\_tracking make: \*\*\*\*\* [Makefile:166: all] Error 2

I used 32-bit instead of 64-bit because it was giving more errors Kindly help me in making this.

Hi @AryanKamal270819  
Welcome to the forums.

I’ve seen this `[Makefile 16x: all] Error 2` error before.  
This was the thread where it came up.  
Hopefully it woks for you.
