RE: Using GDB to debug ia64 files
OKay, so what soltuion do I have ? I have downloaded Cygwi, especially the GDB 20030919-1 package (guess it's what you call vanilla Windows GDB ?). I have tried to compile it for architecture ia64-pc-cygwin, but it failed. Same for ia64-pc-elf. I'de like to add PDB support to the BFD library, but I have problems finding my way into the code. Have an idea of what to read/do first ? If I can manage to add support of the PDB format to BFD, do you think I will be able to do what I'de like to ? Is there a sufficient support in GDB for doing what I'de like to ? 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 ?

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.
