Dear All,

I experienced the same problem.

The error will occur if the path of the dll is too long, OR if gdb can not
access the dll for some reason. If the dll can not be accesed, then the call
to realpath() fails, and you get the "dll path too long" message.

In my case, the path was never too long. Making the change below lets you
debug your applications:

--- gdb-7.9.1-1.src/gdb.i686/src/gdb-7.9.1/gdb/windows-nat.c.orig 2015-11-23

@@ -623,7 +623,8 @@ windows_make_so (const char *name, LPVOI
free (rname);
}
else
- error (_("dll path too long"));
+ warning (_("dll path too long, or can not be accessed '\"%s\"'"),
+ name);
}
/* Record cygwin1.dll .text start/end. */
p = strchr (so->so_name, '\0') - (sizeof ("/cygwin1.dll") - 1);

Hope this helps!
Tim
