[issue20305] Android's incomplete locale.h implementation prevents cross-compilation

[Xavier de Gaye]

Xavier de Gaye added the comment:

This error:
_curses.error: setupterm: could not find terminfo database

does not occur for me after removing the '--disable-database 
--disable-home-terminfo' options from the configure options used to 
cross-compile ncurses, and after setting the TERMINFO environment variable to a 
location where the the compiled description of the vt100 terminal is set. See 
https://bitbucket.org/xdegaye/pyona.

Also, with API level 21 (Android 5.0), the build of python3 with the official 
android toolchains (that is, without resorting to external libraries for wide 
character support) runs correctly and the python test suite is run with few 
errors, so IMHO this issue may be closed.

Chi Hsuan Yen added the comment:

curses was broken and now it's fixed. Yes - Android's locale patch is no longer 
necessary in _curses either. However, there are runtime errors:

shell@ASUS_Z00E_2:/data/local/tmp $ python3.6 -c 'import curses; 
curses.initscr()'   
Traceback (most recent call last):

Thank you, this is excellent!  Does that mean that all locale patches are no 
longer needed? Here is one left (perhaps accidentally):

[Chi Hsuan Yen]

Chi Hsuan Yen added the comment:

Android NDK provides an "android-support" package [1]. There is no 
documentation other than README in its git repository, I guess it's a 
'compatibility layer' between applications targetting a complete C library and 
Android's BioniC. With my patchset [2], Python builds and runs on my ASUS 
Zenfone 2 (Android 5.0.2). Patches proposed in this issue are no longer 
necessary.

Stefan Krah added the comment:

Consider the libmpdec part rejected.  It is too much work given that
external libmpdecs need to be compatible and Android can use the Python
version of decimal.

[issue20305] Android's incomplete locale.h implementation prevents cross-compilation

[Stefan Krah]

Stefan Krah added the comment:

I've been looking into this, and the only option provided by the Android NDK 
involves cross-compiling Python on a regular machine. This would require some 
custom commands before and in between the builds, to build a host Python first, 
then cross-compile the Android Python, and then start the emulator, transfer 
the binaries there and run the tests over adb. Can buildbot provide 
functionality so this can be configured on-slave, or would it require setting 
up a seperate master?

I'm not sure. Antoine, do you think this is possible?

The master can ask the slave to execute arbitrary commands. So, as long
as you implement the necessary steps as well-known commands executable
by the slave, you can then tell me how to insert them inside the build
process.

However, the only point of setting up an Android buildbot would be if:
1) Python actually builds correctly on Android
2) someone monitors the buildbot for failures and tries to act on them

[issue20305] Android's incomplete locale.h implementation prevents cross-compilation

[Shiz]

Shiz added the comment:

I managed to cross-compile Python 3.3.3 for arm-linux-androideabi (using the 
Android NDK r9c) with the patches in this issue, issue 20306 and issue 20307. 
It did require a small additional patch which addressed the fact that the host 
system can't run the generated parser generator, which I'll make an issue for 
as soon as I refactored the patch. The patch allows the user to specify a host 
parser generator that points to a compiled version of pgen that is runnable on 
the host through the HOSTPGEN environment variable in ./configure.

Compiling the tip proved somewhat harder as the cross-compilation requires a 
host Python of the same version, which I didn't have. I formatted a patch which 
allows the user to supply a special host python path using the HOSTPYTHON 
environment variable to ./configure. I'll make an issue for that soon, and will 
bundle it with the HOSTPGEN patch if it's seen as a sufficient approach.

As far as maintaining an Android port for CPython goes; I may be interested in 
this as I'd need to regularly use it anyway. Can anyone tell me what the 
possibilities are here?

Since in the meanwhile the tip was updated to unconditionally include locale.h 
in Python/fileutils.c according to issue 19036, here's an updated patch for 
this issue that applies cleanly against the tip.

There seem to be some external ports already. -- On the other hand, if we
integrate your patches, we'd sort of make Android officially supported.

The problems with this are:

   a) In the past proponents of non-mainstream platforms have not been
  very active after an initial enthusiasm.

   b) There were no build slaves (See http://www.python.org/dev/buildbot/)
  for these platforms.

   c) Many (or all) core committers did not have access to the platform
  in question.

Wikipedia claims that QEMU also powers the Android emulator which is part of
the Android SDK.  Can you run a build slave with network access and also run
the test suite in this emulator?

Running a build slave is rather easy, see:

https://wiki.python.org/moin/BuildBot
http://bugs.python.org/file24399/buildslave_install.txt

I'd say Android is quite a common platform these days, although I'd concur that 
it's not particularly easy to run Python OOTB on. :)

Marc-Andre Lemburg added the comment:

I'd be +1 on such a patch if we were to officially support Android, but we'd 
need a volunteer to champion for this (which would be a good thing, IMO).

Otherwise, such changes need to be maintained externally.
