I have ever compiled the lib before, this time I want to make for ARMv8 64bit and get error like this:

$ make BIT=64

Use make clean to clean the build:

$ make clean
rm -rf *.o *.a *.so java jniLibs snowboy-detect-swig.cc

Build again and it succeeded:

$ make BIT=64

Aha, strange thing! If you have ever compiled before and get errors like this, just make clean and try to build again.

Hope this helps a bit!
