[yocto] Updating daisy -> Python.h not found

[Neuer User]

Hmm, going deeper into the configure error I found the following:

File
/home/ubuntu/yocto/build/tmp/sysroots/i686-linux/usr/lib/python3.3/distutils/sysconfig.py
contains in line 19:

PREFIX = os.path.normpath(sys.prefix).replace( os.getenv("BUILD_SYS"),
os.getenv("HOST_SYS") )

This gives error

TypeError: Can't convert 'NoneType' object to str implicitly

It does the same if I type this line on python3 on my host computer.

Looking into the sysconfig of python3 of my ubuntu installation, it does
NOT HAVE this line!

here are the lines from python3 sysconfig.py from yocto:

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

EXEC_PREFIX = os.path.normpath(sys.exec_prefix).replace(

Now, I don't know if that changed with the daisy update, but it
definitely seems to be wrong.

Any python3 expert out there? Can we find out (git blame) when these
lines were changed last?


EDIT: found it, it's this patch:

./poky/meta/recipes-devtools/python/python3/12-distutils-prefix-is-inside-staging-area.patch

and it is from 2013-05-14, so pretty old... :-(

That leaves the question why it gives an error now after updating daisy,
but not before.

Here is the log_configure from before updating daisy:
