"Solaris 2.7" does not exist. It was relabelled "Solaris 7" as it went out
the door. [One can find occasional places where "2.7" has not been painted
over with "7", though.]
SunOS 5.7 is the operating system component of Solaris 7.
SunOS 5.6 is the operating system component of Solaris 2.6.
Programs compiled for Solaris 2.6 (SunOS 5.6) and using only documented
stable interfaces should work under Solaris 7 (SunOS 5.7), but not necessarily
Does that answer your question?
Be warned that when most people compare and contrast "Solaris and SunOS",
they really mean "SunOS5 and SunOS4" (or "Solaris 2 and Solaris 1").
Binary compatibility across *that* divide is a much more interesting
question, but sadly not the one you asked. :-(
