$ make -C _gnu-make/ libsuffix=.so binsubdir=android CC=/tmp/android/bin/arm-linux-androideabi-gcc CFLAGS='-march=armv7-a -mfloat-abi=softfp -O2' $ make -j -C _gnu-make/ libsuffix=.so binsubdir=android CC=/tmp/android-toolchain/bin/arm-linux-androideabi-gcc CXX=/tmp/android-toolchain/bin/arm-linux-androideabi-g++
Depending on whether you compile for an Android version that requires PIE
executables, add `CFLAGS='-fpie' CXXFLAGS='-fpie' LDFLAGS='-pie'` accordingly.
Loading page aligned library straight from APKs is supported. To test, use the
following:
$ zip -Z store app bin/android/library.so
$ zipalign -v -f -p 4 ./app.zip ./app.apk
Then copy `bin/android/executable` and `app.apk` to your Android device and
there launch:
$ ./executable --load-library=app.apk!/bin/android/library.so
