That's a question for the GDB folks so I'll leave that for them. I'm not sure if there's a patent issue with PDB though. >Last question : what is precisely this "vanilla Windows version of GDB" >you're talking of ? Where can I get it, if it's not the one of Cygwin ? A "vanilla Windows version of GDB" is GDB without Cygwin. It targets the Windows platform without the POSIX emulation that the Cygwin DLL provides. I suggested it simply because it's not obvious to me that you need Cygwin under-the-hood to do what you want to do. Keeping Cygwin in the equation may just complicate what you want to do. But that's for you to decide. It's just a suggestion. You can find a vanilla Windows version of GDB at <http://www.mingw.org/>. >> -----Message d'origine----- >> De : Larry Hall [mailto:[EMAIL PROTECTED] >> Envoye : mardi 29 juin 2004 16:21 >> A : [EMAIL PROTECTED]; Cygwin List; [EMAIL PROTECTED] >> Objet : RE: Using GDB to debug ia64 files >> >> >> At 02:22 AM 6/29/2004, you wrote: >> >I must add a precision : only the platform is ia64.
