Adding the Python3 - pip Installation Package
This manual describes how to add python3-pip to a buildroot system.
Modification Method
Modify Configuration File: buildroot/package/Config.in
Add pyhon-pip/Config.in
Unzip the python-pip archive of the attachment in the buildroot/package directory
python-pip-20240425100624-9049ncj.zip
Modify the defconfig file used by buildroot
Execute make menuconfig in the buildroot/output/OK3568 directory to select python3 and python-pip
After modification, save the modified.config file to buildroot/configs/OK3568 _ defconfig
After saving, you can compile the whole package. When compiling, you can see that the download, compilation and installation of pip related packages are successful.
Flash the compiled file system to the development board to use the pip command.
Potential Compilation Errors
Error During Compilation:
Solution:
Solution: Re-link the symbolic link for OK3568-linux-source/buildroot/output/OK3568/host/bin/python to point to python3.
cd buildroot/output/OK3568/host/bin
rm python
ln -s python3 python
After re-establishing the link, recompile. After successful linking, the result of ls -l python should be as shown.
SSL Error when running pip install on the board after flashing:
Solution:
Delete the Python-related files in the OK3568-linux-source/buildroot/output/OK3568/build/ directory and recompile. Installing pip depends on SSL. If a full compilation was previously completed during the first issue, it was done using python2 for SSL compilation.
rm buildroot/output/OK3568/build/python-* -rf
./build.sh buildroot
Once the compilation is complete, flash the new build to the board and verify its functionality. You can then proceed to test by installing opencv-python.
If you encounter an error about the pip package download failing, place the specified package files into the buildroot/dl/ directory.
