v1.03 prerelease - Full Linux port of crnlib/crunch, in progress - still more testing to do, and some cmd line options (such as -timestamp) don't work under linux yet, but the core stuff (compression/decompression/transcoding) should work fine and performance under Linux is comparable to Windows. The 3 examples haven't been ported yet.

+New for v1.03 [4/26/12]: crnlib more portable, Linux Port
+------------------------------------------------
+
+v1.03 has been ported to Linux. It's still a work in progress. A few features 
+of the command line tool don't work under Linux yet (such as -timestamp), 
+but the core functionality (compression/decompression/transcoding) should work
+OK. I'm currently testing crnlib/crunch with Codeblocks 10.05 under Ubuntu x86.
+
