From: Raymond Toy on 6 Jan 2010 09:38 Is it possible to build binaries on Solaris 10 that will run on Solaris 8? I'm not using any special libraries other than libc, libm, libnsl, libsocket, and libdl. What I currently see is that this app links in libm.so.2, which doesn't exist on Solaris 8. But if I change the link command to link just /lib/libm.so.1, the app links just fine and runs just fine on both 8 and 10. (Only a few quick tests were done, though.) Is that ok, or will it eventually be doomed for failure? Ray

The O/S developers try very hard to ensure that software built on X-N will work on Release X, X+1, X+2, etc. Many software developers purposely work under Release X-N in order to be able to run on all reasonably current releases of the O/S. Today "reasonably current" could be taken to mean Solaris 9 and Solaris 10. Support for running under Solaris 8 MAY be available but you can't count on it. If I were developing software for sale I would work under S8 and test on S8, S9, and S10. With Solaris 8 being something like seven years old now many developers would not bother with supporting it.

Don't do it. If I were you, I'd strongly reconsider the need to support something as ancient as Solaris 8. It passed its EOSL a couple of years ago; it really is bereft of life! That said, if Solaris 8 is still a must for you, you do have one way out: use a Solaris 8 Container on one of your Solaris 10 machines. Build your app within the S8 container, and all will be good.

But yes, I know of many software vendors still certifying their software only for S8. Although that EoSupport in 3/2012 should scare them somewhat. Sigh. |
