We found a problem compiling lsof 4.77 for Solaris 10 6/06, see this bug:
6440943 <sys/kstat.h> should include <sys/types32.h>
When you compile lsof with Sun’s compiler you get “syntax error near caddr32_t”. There’s a similar failure for gcc.
The workaround in the bug allows lsof 4.77 to be compiled.
We also found that you have to recompile lsof for Solaris 10 6/06. Versions compiled for Solaris 10, Solaris 10 3/05 and Solaris 10 1/06 don’t work properly. Here’s a diff of the two different outputs:

The UDP and TCP ports are shown incorrectly. I’ve passed this on to the lsof maintainers.

/ July 11, 2006Why would one even bother compiling a piece of SW that peeks into private kernel interfaces and is always behind, when there is DTrace?
Sorry, but that’s pretty pointless.
Peter Harvey
/ July 11, 2006Good point – but bear in mind that DTrace is Dynamic Tracing. In other words, we can dynamically trace the operation of the system. Much of what lsof extracts is static state information related to processes and their open files.
One possible solution to this would be to rewrite lsof to use Compact ANSI-C Type Format (CTF) – symbolic debugging information available in the kernel and user libraries. One way of doing this would be to write it as an mdb module.

/ July 12, 2006lsof has its place. Yes, you can do everything that lsof can do with DTrace, fuser, etc. etc. That’s not the point, though. lsof is a tool that has been around for years and people use it, like it, got used to it. It’s definitely easier to use than writing a D script.
Btw. even the older versions of lsof (I also tried 4.76) do not compile on Solaris 10 6/06. My work-around was to just add an #include <sys/types32.h> into machine.h.
