Re: Debugging with cygwin tools
I'm having the exact same problem on win64 with gdb. The PATH variable has been set manually to avoid possible syntax errors, but the same problem exists when I don't shorten the PATH. Cygcheck doesn't list any dlls as missing. gdb works on my win32 computer. Any other ideas?
