## Cross-compiling for other platforms
The Makefile contains rules for cross-compiling the native library for other platforms so that the snappy-java JAR can support multiple platforms. For example, to build the native libraries for x86 Linux, x86 and x86-64 Windows, and soft- and hard-float ARM:
- $ make linux32 win32 win64 linux-arm linux-armhf
+ $ make linux32 win32 win64 linux-arm linux-armhf linux-aarch64
If you append `snappy` to the line above, it will also build the native library for the current platform and then build the snappy-java JAR (containing all native libraries built so far).

* armhf: `sudo apt-get install g++-arm-linux-gnueabihf`
+ * aarch64: `sudo apt-get install g++-aarch64-linux`
Unfortunately, cross-compiling for Mac OS X is not currently possible; you must compile within OS X.
