Need support for SunOS

Hi, I have this error when I run cassandra on my server:

I've realised that snappy-java doesn't have native library for SunOS.

Is it possible to compile it for this OS ?

My System.properties:
os.arch=amd64
os.name=SunOS
os.version=5.10

I haven't tried using SunOS (spark machine?), but it might be possible since no special configuration is required to compile native library of snappy-java.

Fetch the source code and try make native & make commands.
If the compilation of the native library succeeds, the resulting native library and a new snappy-java jar file will be generated in target folder.

While SunOS is Solaris, it runs on both x86 and the Sun specific Sparc
architecture. Here it looks like he is using amd64, not sparc.

I had a few issues compiling this on Solaris, firstly you need to use gmake (GNU make) rather than the standard Solaris make. Second you need to edit Makefile to use gtar instead of tar. I also added OS arch targets for SunOS-x86 and SunOS-amd64 and pointed those at the linux equivalents (as the linux jni.h has a reference to solaris and the default one points at mac), I also removed the m32 and m64 tags on SunOS as solaris handles those in a different way.

It compiles and the tests execute fine now. This was on an x86 box running Solaris 11.1.

@Craigacp
Thanks for the success report. Could you show me your fix made to Makefile scripts? (via pull request or patch)
I would like to integrate these changes.

[Craigacp]

I don't think the SunOS-amd64 target actually did anything so I've removed it (as it wasn't used by the 64-bit machine I was building on), but I added sparc build targets and checked those work. The pull request is in now, but I'm not that familiar with GitHub so I can't add it to this issue.

[xerial]

Thanks to @Craigacp's contribution, Makefile has been modified to be able to compile native libraries for Solaris (x86 and sparc).

@Craigacp
Could you send another pull request that includes the following native libraries?
src/main/resources/org/xerial/snappy/native/SunOS/x86/libsnappyjava.so
src/main/resources/org/xerial/snappy/native/SunOS/sparc/libsnappyjava.so

I am now preparing a release build for snappy-java-1.1.0, so it is the best timing to integrate them.

[xerial]

native libraries for SunOS are integrated to the develop branch. Now close this issue.

[mukhanov]

Thank you guys!

@Craigacp
Could you build Solaris x86 and Sparc libraries based on the current develop branch?
Yesterday, snappy-1.1.1 is released and we need to recompile snappy-java for this version.
