Broken jpeg recipe for NDK 23b?

[gbm001]

Checklist

• the issue is indeed a bug and not a support request
• issue doesn't already exist: https://github.com/kivy/python-for-android/issues
• I have a short, runnable example that reproduces the issue
• I reproduced the problem with the latest development version (p4a.branch = develop)
• I used the grave accent (aka backticks) to format code or logs when appropriated

Versions

• Python: 3.10.4
• OS: Ubuntu 22.04
• Kivy: 2.1.0
• Cython: 0.29.28
• OpenJDK: 18

Description

My main app, which uses Pillow, no longer works. I think I have tracked the issue down to the combination of NDK 23b and the jpeg recipe.

#    -----------------------------------------------------------------------------
#    List as sections
#
#    You can define all the "list" as [section:key].
#    Each line will be considered as a option to the list.
#    Let's take [app] / source.exclude_patterns.
#    Instead of doing:
#
#[app]
#source.exclude_patterns = license,data/audio/*.wav,data/images/original/*
#
#    This can be translated into:
#
#[app:source.exclude_patterns]
#license
#data/audio/*.wav
#data/images/original/*
#


#    -----------------------------------------------------------------------------
#    Profiles
#
#    You can extend section / key with a profile
#    For example, you want to deploy a demo version of your application without
#    HD content. You could first change the title to add "(demo)" in the name
#    and extend the excluded directories to remove the HD content.
#
#[app@demo]
#title = My Application (demo)
#
#[app:source.exclude_patterns@demo]
#images/hd/*
#
#    Then, invoke the command line with the "demo" profile:
#
#buildozer --profile demo android debug

To fix the issue, I had to copy the jpeg recipe and make two changes:

1. change the line:
   shprint(sh.rm, '-r', 'CMakeCache.txt', 'CMakeFiles/')
   to
   shprint(sh.rm, '-rf', 'CMakeCache.txt', 'CMakeFiles/')

(this doesn't really matter, but it gives an annoying error once the build has failed once)

and 2)
comment out the line:
'-DCMAKE_SYSTEM_PROCESSOR={cpu}'.format(cpu='arm'),

(which is the real source of the problem, I think)

[kengoon]

The issue is based on the new release of Ubuntu 22.04, I am using POP OS 22.04 (Ubuntu 22.04) which has cmake version 3.22.1 installed and this gives the above error stated by @gbm001 . On the previous Ubuntu 21.04 version it has cmake 3.18.1 installed and it compiles all fine.

I made a few changes on the recipe myself on line 33

'-DCMAKE_SYSTEM_PROCESSOR={cpu}'.format(cpu='aarch64' if arch.arch == "arm64-v8a" else "armv7-a")

I changed the cpu value to suit the values on this file
/usr/share/cmake-3.22/Modules/Platform/Android-Determine.cmake

  set(NDK_PROC_aarch64_ABI "arm64-v8a")
  set(NDK_PROC_armv7-a_ABI "armeabi-v7a")
  set(NDK_PROC_armv6_ABI   "armeabi-v6")
  set(NDK_PROC_armv5te_ABI "armeabi")
  set(NDK_PROC_i686_ABI    "x86")
  set(NDK_PROC_mips_ABI    "mips")
  set(NDK_PROC_mips64_ABI  "mips64")
  set(NDK_PROC_x86_64_ABI  "x86_64")

  set(NDK_ARCH_arm64_ABI  "arm64-v8a")
  set(NDK_ARCH_arm_ABI    "armeabi")
  set(NDK_ARCH_mips_ABI   "mips")
  set(NDK_ARCH_mips64_ABI "mips64")
  set(NDK_ARCH_x86_ABI    "x86")
  set(NDK_ARCH_x86_64_ABI "x86_64")
endif()

# Validate inputs.
if(CMAKE_ANDROID_ARCH_ABI AND NOT DEFINED "NDK_ABI_${CMAKE_ANDROID_ARCH_ABI}_PROC")
  message(FATAL_ERROR "Android: Unknown ABI CMAKE_ANDROID_ARCH_ABI='${CMAKE_ANDROID_ARCH_ABI}'.")
endif()
if(CMAKE_SYSTEM_PROCESSOR AND NOT DEFINED "NDK_PROC_${CMAKE_SYSTEM_PROCESSOR}_ABI")
  message(FATAL_ERROR "Android: Unknown processor CMAKE_SYSTEM_PROCESSOR='${CMAKE_SYSTEM_PROCESSOR}'.")
endif()

and it works too.

Also commenting out

'-DCMAKE_SYSTEM_PROCESSOR={cpu}'.format(cpu='arm'),

as @gbm001 stated works too

Ah, that makes sense. I'd tried a few different cmake versions (newer and older) but not that far back.

Fixed via #2586, feel free to re-open the issue if you're still encountering it on the develop branch.
