  STDERR:

[RobertFlatt]

I have a suggestion if you are using WSL 1, otherwise not.

[bobwatcherx]

I'm using Linux Mint. and is there any way to solve the error . is it from the ndk version

[RobertFlatt]

Sorry I don't know anything about Mint, or building for Flask. But.....

The is the WSL issue https://github.com/Android-for-Python/Android-for-Python-Users#c-compiler-cannot-create-executables

You might want to look at the issue referenced there, particularly this post kivy/buildozer#1543 (comment) about patching Clang.

[strubbi77]

Have a simular issue on debian 12.0
Tried newest p4a. Python 3.10 and 3.11. Changing recipe version of libffi to 3.4.4.
Added +x to the complete ndk directory.

Every time the build stopped with
configure: error: in /home/pille/.local/share/python-for-android/build/other_builds/libffi/arm64-v8a__ndk_target_25/libffi': configure: error: C compiler cannot create executables See config.log' for more details

`This file contains any messages produced by compilers while

Think I now know what the error is.

For me a changing of export NDKAP="25" to an other value helped.
With API=25 the check process of libffi tries to find arm-lnux-androideabi/25/crtend_so.o but there is no version 25. So it should be NDKAPI != 25

[RobertFlatt]

It appears from the logs above you use 25c and perhaps 25 as well, the Buildozer default is 25b.

[strubbi77]

Buildozer downloads the NDL version specified in buildozer.spec
NDK 25b is the default for Buildozer.
I got no idea why you had to download by hand.

You might try clearing ccache.
Everything seems to point to corrupted build environment(s).

Oh, wait I just realized you are not using Buildozer.
I know that I don't know how to use p4a stand alone. Sorry.

Got it to work again on my new machine.
python 3.11.2
python-for-android 2023.02.10

additional change was that I removed the --requirements line in the .p4a configuration file. Using ndk 25b or 25c makes no difference. Both versions work.
