Openssl Issue: warning: '__ANDROID_API__' macro redefined [-Wmacro-redefined]

[Doritos464]

Versions

• Python: 3.10.12
• OS: WSL2, Ubuntu 22.04.3 LTS
• Buildozer: 1.5.0

Description

I just started using bulldozer and trying to set it up on my machine
I wrote some simple kivy code that I tested as a simple python script and it worked, and I wanted to create it into an APK
After installing all the dependencies I ran the quickstart commands and at the end I am facing an issue with OpenSSL that repeats itself. I tried to look for the solution online but I had no luck.

buildozer.spec

Command:

buildozer init
buildozer -v android debug

#    -----------------------------------------------------------------------------
#    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

another thing that might be relevant is that in the first run of the debug command i saw the following log:

[WARNING]: pkg-config location is not supported on linux for prerequisite: openssl

and I also used the command given by the log to extract the configdata.pm data:

Command line (with current working directory = .):

    /usr/bin/perl ./Configure shared no-dso no-asm android-arm64 -D__ANDROID_API__=21

Hi @Doritos464 !

This is a warning and is expected to show up. 😀

Does the build terminate abnormally?

[Doritos464]

@misl6
This chunk repeats for about 5 minutes after which I stop it with a keyboard interrupt:

<command line>:6:9: warning: '__ANDROID_API__' macro redefined [-Wmacro-redefined]
[DEBUG]:        #define __ANDROID_API__ 21
[DEBUG]:                ^
[DEBUG]:        <built-in>:375:9: note: previous definition is here
[DEBUG]:        #define __ANDROID_API__ __ANDROID_MIN_SDK_VERSION__
[DEBUG]:                ^
[DEBUG]:        1 warning generated.

Should I let it run for longer?

This log repeats multiple times, the build time for the openssl recipe may change based on your development machine hardware specs.

Try to re-run the script and leave it running until it stops.
