Compiling for Arm 64bit fails

[bamirzada]

I tried to compile LibSerial library for arm 64 bit (APP_ABI := armeabi-v7a arm64-v8a), but got the following error below using ndk-build. Wondering if you guys know what is needed to support arm 64 bit ?

Error: [arm64-v8a] Compile++ : serial <= serial_jni.cc

Since glob is missing in NDK, we have to include the code and header in our build. But it seemed that the code I included won't build with 64 bit versions.

[bamirzada]

So, is there a solution as this will come up quite a bit as more devices move to 64bit and require 64 bit libs.

When I replace <sys/_types.h> with <sys/types.h> in glob.h file, it compiles fine for 64-bit and all other architectures.

@sachins works for me, thank you~

Would anyone post the nbew .so for the other cpus?
