How to install aiortc (python module) in STM32MP157F-DK2

[Jaison M]

So basically I'm trying to implement WebRTC and seems like aiortc is its python implementation right now:.

Unable to manually install them using pip3 as it requires some dev-packages.

I tried to install it as a layer using pipoe auto-generated recipe, but no luck as it goes on with errors. A working recipe and additions that has to be done to local.conf or CORE_IMAGE_EXTRA_INSTALL variable would be appreciated :smiling_face_with_smiling_eyes:.

Hi @Jaison M​ 

This recipe generates a package that I have successfully installed on my board (stm32mp157c-dk2):

DESCRIPTION = "aiortc is a library for Web Real-Time Communication (WebRTC) and \
Object Real-Time Communication (ORTC) in Python."
HOMEPAGE = "https://github.com/aiortc/aiortc"

PYPI_PACKAGE = "aiortc"
 
DEPENDS += " \

inherit pypi python_setuptools_build_meta
 
RDEPENDS:${PN} += " \
 ffmpeg \
 libopus \
 libsrtp \
 libvpx \
"
 
BBCLASSEXTEND += "native nativesdk"

I did this quick test with the OpenSTLinux distribution that should be released soon. Results may differ against OpenSTLinux ecosystem 3.1

Ok I tried compiling the layer, but received this error:

Could not inherit file classes/python_setuptools_build_meta.bbclass

How do I fix this?

Hi @Jaison M​ 

As said, I didn't check with ecosystem-3.1 so I guess this error may be explained so.

For ecosystem-3.1, you could try to remove the DEPENDS variable and replace python_setuptools_build_meta inheritance by setuptools3.

Then, you could also downgrade the aiortc version as the internal build mechanism may not be compatible with ecosystem-3.1 but older versions may be compatible.

Best regards,
