Hi All,
I'm finding it very difficult to debug the 32-bit VM on 64-bit Windows using cygwin. The default gdb for 64-bit cygwin simply doesn't work properly, finding set facts in programs that work out side of the debugger. I've tried to build a 32-bit gdb from the 7.11 sources, configuring with ./configure --target=i686-w64-mingw32, but the resulting gdb doesn't find the 32-bit dlls in C:\Windows\SysWOW64', and complains "Don't know how to run.".
Does anyone else have a working gdb for 32-bit programs on 64-bit Windows? How did you build it?
Does anyone else have a working gdb for 32-bit programs on 32-bit Windows? How did you build it? Do I need to create a 32-bit cygwin installation on 32-bit windows for this to work?
Does anyone have the cygwin gdb 7.8 sources or a pointer to them? One poster claimed that 32-bit gdb on cygwin only works if compiled from the 7.8 sources.
Any other ideas?

Hi Eliot, I've installed both a cygwin32 and cygwin64 for that reason... Even if cross compilation works well, cross debugging does not.

Thanks Nicolas! I'll get a 32-bit Windows and install 32-bit Cygwin on it. And I'll update the HowToBuild
