library output support for armeabi-v7a ?

[ghost]

Dear tomaka,
When will you add support for armeabi-v7a architecture ?
We need it so much.
Thanks.

unless I misunderstand you can do this now by specifying build targets in your Cargo.toml

[package.metadata.android]
build_targets = [ "armv7-linux-androideabi" ]

It's required to pass -march=armv7-a to arm-linux-androideabi-gcc to generate ARMv7a code instead of ARMv6.

I'm trying to use armv7, and all the options seem to be working (if I add the build target, the -march=armv7-a option is automatically added) but I still get linking errors.

android-rs-glue/examples/basic/target/armv7-linux-androideabi/debug/deps/example-5e3c12e16b8a2e10.example2.rcgu.o: requires unsupported dynamic reloc R_ARM_THM_MOVW_ABS_NC; recompile with -fPIC

On arm-linux-androideabi I managed to fix the linking error using the no-pie option, but on armv7 I cannot get it to work even with:
RUSTFLAGS='-C relocation-model=dynamic-no-pic -C link-args=-no-pie -C link-args=-fPIC' cargo apk run

@talhazengin @dten @davll does armv7 work for you? Is it even supposed to work right now?

Maybe the problem is related to this rust issue: rust-lang/rust#40145

Thanks

I finally got it to work !

The good flags are:
RUSTFLAGS='-C relocation-model=pic -C link-args=-no-pie -C link-args=-Wl,-Bsymbolic'

It seems this was fixed by #170. But even if it wasn't, #223 fixes it.
