Scott,

Thanks for your speedy reply.  I think I'll have to try the emulator.  The only problem I have is with linking this library file - everything else is OK, but I don't have access to the source code for the library so I can't recompile it.

Once again, thank you for helping me out.

Regards
Paul

Paul,

I'm not sure if (or how) one might convert a .so to a .a file. You'll get other answers (I'm not one of the list experts that's for sure ;-)

But if I understand you correctly, you were given ".so" binary files. You won't be able to just take compiled Linux code and run it in Cygwin: Cygwin is not UNIX.. Cygwin is a UNIX-like wrapper around Windows. Cygwin is not an emulator for Linux binaries.

Or maybe I misunderstood.

If you have Linux binaries you want to use on a Windows PC, you can *try* re-compiling that code under Cygwin. Assuming a few things, UNIX code generally compiles under Cygwin and gives you a Windows binary.

The other thing you can try is Linux emulation under Windows. I don't know if this is the best solution for you but it will give you a true Linux sandbox to play in. If you want an emulator samdbox, try Plex86 (formerly FreeMWare):
http://savannah.nongnu.org/projects/plex86

Plex86 is a work-in-progress and I have not tried it. It is FREE and may be what you want.

Another choice is FreeMWare, which is not free and not cheap. I happen to like VMware (and have not had time to try plex86 so I don't know how the two compare).

Hope this helps,
Scott
