Rock64 U-Boot compilation python issue

[Werner]

Since this is a different issue I split this topic into a separate one to take care of or check at least somewhen.

 

------------------------------------------

Oh well. There IS something wrong but not with the toolchain download...

Seems to depend on Python2

Yup. Forcing Python2 works.

Not sure if Python2 was still default on Bionic but I guess so.

Might become an issue with building on Focal in future. Need to test this somewhen...

I am only building on Focal for some time and I see no troubles.

Yeah I assumed it is nothing but wanted to make sure.

Probably messed with Python version ages ago on that machine and forgot about it.

Most of the time these are dependency-issues. You need to install a package called python-dev. This package includes header files, a static library and development tools for building Python modules, extending the Python interpreter or embedding Python in applications. When encountering this error please note before the error it may say you are missing a package or header file — you should find those and install them and verify if it works.

 

For Python 2.x use:

 

$ sudo apt-get install python-dev

 

If you using python 3, try to replace python-dev with python3-dev

For a specific version of Python 3, replace x with the minor version in

 

$ sudo apt-get install python3.x-dev
