Compiling with Existing Dephai-Core

[samialperen]

I have a specific docker for oak-d related stuff. I installed depthai-ros (as well as depthai-core) using [https://raw.githubusercontent.com/luxonis/depthai-ros/main/install_dependencies.sh](this script). I can use depthai-ros and everything without any problem. I want to install depthai-python inside my docker too, but I do not want to install depthai-core again. Is there any way to change CMakeList to depthai-core's location where it was installed with depthai-ros?

@samialperen - sure:)

Add the following CMake defines: -D DEPTHAI_PYTHON_USE_FIND_PACKAGE=ON -D depthai_DIR=[path/to/install/lib/cmake/depthai]

@themarpe I am getting this error.

@samialperen that'll be a minor issue when depthai-python & dephtai-core aren't cloned alongside. In this case I'd suggest either: clone depthai-python with submodules, but still use the above CMake defines Or copy that file from depthai-core into cmake/ of depthai-python folder

[samialperen]

@themarpe, so my overall goal is to just use device_manager. I tried the second method you suggested and now have this error. Computation and space is quite limited for my current project, so as long as I can make the device manager work, I do not need anything else from depthai-python

@samialperen To use device manager, just install latest depthai using python3 examples/install_requirements.py

For above, yeah, you'll have to clone both - do git submodule update --init --recursive in depthai-python

[samialperen]

Thanks!
