Python3

Hi,
the following patches include python3 in ipfire. 

Unfortunately, the flash image build no more. The build fails with a 
tar 
error complaining about to less disk space. I did not found out what the 
problem is, so somebody else has to investigate time into this problem 
to find a solution.

Regards Jonatan

[PATCH 1/2] Prepare for python3

[Jonatan Schlag]

[-- Attachment #1: Type: text/plain, Size: 795 bytes --]

The build of ipaadr fails with python3 because two possibilities of
/usr/lib/python* are availible. This patch set the path to
/usr/lib/python2* to make the path clear.

Hi,

thank you for submitting this.

I merged this and for me, the flash image couldn't be generated either. The
reason for that is that we allocate a partition of a fixed size (which is
~700MB) right now. The system is extracted onto that partition and all is put
into the image which then is small enough to fit on a 1GB storage device. As
soon as the system boots up for the first time, it increases the partition to
maximum size.

However, with adding Python 3 to the core system, it didn't fit into the 700MB
any more. I therefore made it an add-on package which is still rather huge
(~20MB). Is there any requirement this should be in the core distribution? AFAIK
nothing is using this by default, hence it could easily be an add-on.

Best,
-Michael

Hi,

sorry guys, but this won't build here:

Its always (_build.packages.log):

...

+ cd /usr/src/lfs
+ make -f python3 LFS_BASEDIR=/usr/src dist
'/usr/src/config/rootfiles/packages/i586/python3' ->
'/install/packages/package/ROOTFILES'
tar:

Cannot stat: No such file or directory
tar:

... and so on ...

E.g., script is searching for:

_sysconfigdata_m_linux_x86_64-linux-gnu.cpython-36.opt-1.pyc
                       ^^^^^^
It builds:

_sysconfigdata_m_linux_i386-linux-gnu.cpython-36.opt-1.pyc
                       ^^^^
"Fixes for rootfile" (or something similar?) needed!?

Best,
Matthias

Hi,

Ok, got it:

"x86_64 refers to 64-bit processors. i386 refers to 32-bit processors."

Replaced all "x86_64" in ".../config/rootfiles/packages/i586/python3"
with "i386" and this seemed to work.

Sent rootfile...

Best,
Matthias

Thanks.

I assume that we will have the same issue with ARM but I could not
download a rootfile from a nightly build at the moment...
