Does anyone know if it is possible to run SVR4 binaries on SVR3.2? I'd like to get the Dell SVR4 package to develop binaries for ISC 2.0.2. Can libraries from SVR3.2 be copied over to SVR4 and used when linking? -- John W. Temples -- john@jwt.UUCP (uunet!jwt!john)

Since 3.2 binaries will work correctly on SVR4, I would copy the ISC tools over to your SVR4 system in a chrooted enviroment and do the compiles there. I successfully used this mechanism to develop Xenix software under ISC. -- Conor P.

Temples -- john@jwt.UUCP (uunet!jwt!john) You cannot run binaries made on V4 on a 3.2 system, it does not produce COFF files, uses ELF instead. The opposite is true however, i.e. 3.2 runs okay on V.4. If you intend to develop explicitly for 3.2 [ why? ;-) ] then you should do it on a 3.2 machine.

It is possible to develop COFF binaries on SVR4.0 by installing the SVR3.2 C Compilation System. It is even possible to have the SVR4.0 compilation system installed at the same time. To accomplish this: install the SVR3.2 CCS *first* (this keeps the SVR4.0 CCS from making links from "/bin/cc" to "/usr/ccs/bin/cc", etc.); then install the SVR4.0 CCS. Since the SVR4.0 CCS resides under "/usr/ccs", you can control which version you use by where "/usr/ccs/bin" comes in your $PATH. This capability is specifically intended for people who want to move to SVR4.0 while still being able to develop for SVR3.2.
