Building Insight-6.1 under Cygwin

["Peter Stephens" <ptfoof at sbcglobal dot net>]

I thought this might help some of the Cygwin people.  I am not a great
developer, but managed to put this together from the various sources and
e-mails out there.  This is for an AMD K6-2/500 host running Cygwin (see
cygsum.txt attachment for details - also shows packages I have).

i586-pc-cygwin, AMD K6-2/500 running Windows 2000 Professional

Download sources via Insight-6.1 SNAPSHOT, not development sources.

1. Add "-mnop-fun-dllimport" to the AC_FLAGS variable in tcl/win/Makefile.in
and tk/win/Makefile.in

2. Add a symbolic link to X11 in the gdb directory, gdb$>ln -s
../tk/xlib/X11 X11

3. Install patch in main configure file, src/configure.in

Note:  I had to add Bison and Flex in addition to my current cygwin
packages.

Libraries have been installed in:
   /usr/local/lib

4. Install patch in targetselection.itb (and other files referring to com1!)

     AIX     { set port /dev/foo1 }
                   
       # Failed.  Find out why.
       if {[string first "permission denied" $msg] != -1} {
 	# Port is there, but busy right now. That's OK.
-	lappend plist com$i
+	lappend plist /dev/com$i
       } elseif {$i > 4} {
 	# if we've scanned the first 4 ports, then quit when we find no more

 	set quit 1
                   
     } else {
       # We got it.  Now close it and add to list.
       close $fd
-      lappend plist com$i
+      lappend plist /dev/com$i
     }
   }
   return $plist

5.  Change references to com1 in any gdbtk.ini to '/dev/com1'

Hope that this helps a little. - Pete
