STM32MP1 trying to add GCC

[jgauthier]

Hello,

I have several python modules I am trying to install that require building something in C. I've read through this and completed a build. I got to the part about adding layers and I'm lost. I've not built a distribution using these tools before and layers are a foreign concept. I can't tell a) what layer GCC is in, nor b) how to add that layer to the final image to be flashed.

Any advice? I've found an older thread but this method is not longer supported by bitbake.

Hi @Community member​ 

Could you share python modules you need?

Thx

I'm looking to add python-can which requires logging, which requires sqlite3, which requires building.

I am trying to add FastAPI, and it's web server (uvicorn) which also has build requirements.

I did not check if these are available through apt, because I assumed they werent.

I discovered that the syntax is actually:

IMAGE_INSTALL:append = " packagegroup-core-buildessential"

and I am trying to run my image again

Does it fulfill your requirements?

Thank you. That does install the CAN module. As far as the FastAPI system, no.

I ended up building the whole distribution, which created a lot of debian files.

I made an internal APT repository and pointed my STM32MP1 device to it and installed gcc, g++, binutils, make, etc.

Obviously, building on a platform like this is not desirable and it's my hope that it is one and done.

I am currently in the middle of building the application. I had to add a temporary swapfile since the build consumed all the physical memory.

Hi @Community member​ 

The FastAPI and uvicorn are available as PyPI modules (https://pypi.org/project/fastapi/ and https://pypi.org/project/uvicorn/)

Follow the wiki https://wiki.st.com/stm32mpu/wiki/How_to_add_a_customer_application to add the two recipes for each module python3-fastapi_0.92.0.bb and python3-uvicorn_0.20.0.bb (current versions today).

The new recipes should roughly follow the pattern:

DESCRIPTION = "<blabla>"
HOMEPAGE = "<url to FastApi / unicorn>"
LICENSE = "<license of FastApi / unicorn>"
LIC_FILES_CHKSUM = "file://<LICENSE name>;md5=<licence md5>"
 
SRC_URI[sha256sum] = "<sha256sum of the component>"
 
inherit pypi setuptools3
 
RDEPENDS:${PN} += " \
  <all runtime dependencies required by the module>
"

Run the commands bitbake python3-fastapi and bitbake python3-uvicorn to build your packages.

Best regards,
