SPARC ->x86 Binary translation

Some additinal info:
Our production machines run Solaris 8 on x86 32-bit platforms. The library files we need to incorporate are available in Sparc 32-bit and  x86 64-bit flavours.  Can we conert x86 64 bit binary to 32-bit binary? or Sparc 32 bit to x86 32 bit?

There really isn't a practical solution to your immediate question. There isn't a practical way to incorporate libraries from different archs like you are describing.

I think you need to take a step back and explain why you want to do this, and be more specific than "need to incorporate sparc 32-bit ..flavour"

You really should consider doing something to get off of Solaris 8. It is very old and unsupported now. You could use branded zones on Solaris 10 to upgrade.

If you explain what your goal is, it might be possible with some kind of virtualization, like with virtual box. But we need to know more about what you are trying to accomplish.

We are using Brightmail 4.0 as spam filter with postfix in Solaris x86 32-bit environment. Now are upgrading to Brightmail 6.x. Here's the problem: Brightmail 6.x SDK do not have x86 32-bit libraries. Is there a way to do this without going to upgrade our machines?

Complain to Brightmail. Since 32-bit programs will run on both 32 and 64 bit versions of Solaris, it would seem that it makes sense to provide the 32-bit version if you are only going to do one. Of course, it may be that their product requires the 64 bits address space to run well, in which case trying to convert to 32 bits is a non-starter anyway.

They do not have any plans for 32 bit x86.  Has anyone heard about tools like  http://web.archive.org/web/20040127234554/http://transitives.com/ ?
