error building for android #1

Open tGrothmannFluffy opened 3 months ago

tGrothmannFluffy commented 3 months ago

Hi there,

I'd love encode audio to mp3 in an android app using the flutter rust bridge. I can build locally fine, but building for android results in:

  configure: error: cannot run C compiled programs.
  If you meant to cross compile, use `--host'.
  See `config.log' for more details
  thread 'main' panicked at /Users/[username]/.cargo/registry/src/index.crates.io-6f17d22bba15001f/autotools-0.2.7/src/lib.rs:790:5:

  command did not execute successfully, got: exit status: 1

  build script failed, must exit now
  note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
note: If the build failed due to a missing target, you can run this command:
note: 
note:     rustup target install armv7-linux-androideabi

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:cargoBuildDebug'.
> Process 'command 'cargo'' finished with non-zero exit value 101

Can you please try to use feature target_host

Autotools are not very great for cross compilation so I normally prefer to build with docker image or via cross

Android documentation has information on autotools but I'm not sure how reliable it is https://developer.android.com/ndk/guides/other_build_systems#autoconf

👍 I'm getting compiler errors now:

I think I may need to define STDC_HEADERS to make it work

DoumanAsh commented 3 months ago

@tGrothmannFluffy can you show full build output from clean build? Add verbose option as -vv

DoumanAsh commented 2 months ago

I made patch to try to work around android cross compilation Please try to test with it https://github.com/DoumanAsh/mp3lame-sys/pull/2
