Create a standalone Android toolchain using the SDK script:

Android$ ./Sdk/ndk-bundle/build/tools/make_standalone_toolchain.py --arch arm --api 21 --install-dir ~/forge/android-toolchain

Building

mkdir build
cd build
LDFLAGS=-static CFLAGS="-fPIC -O3 -fomit-frame-pointer -ffast-math -march=armv7-a" CC=$(pwd)/../../android-toolchain/bin/arm-linux-androideabi-gcc cmake ..
make

Testing

adb push ./getaddrinfo_example /system/bin/
adb shell
/system/bin/getaddrinfo google.com
