+      You'll have to fix the following bug:

+    -GTK & VMS Porting library (only needed for wxGTK)
+       ( from http://www.openvms.digital.com/openvms/products/ips/gtk.html )
+
+    -Redefine the logical SYS$LIBRARY in such a way that it also points
+     to the includefile/library directories of the above packages:
+     i.e.
+$ define sys$library sys$sysroot:[syslib],-
+     $disk2:[joukj.public.xpm.xpm.lib],-
+     $disk2:[joukj.public.jpeg.jpeg],-
+     $disk2:[joukj.public.png.libpng],-
+     $disk2:[joukj.public.tiff.tiff.libtiff],-
+     $disk2:[joukj.public.png.zlib],-
+     $disk2:[joukj.public.gtk.gtk.glib],-
+     $disk2:[joukj.public.gtk.gtk.glib.gthread],-
+     $disk2:[joukj.compaq.porting_library.dist.include]
+
+    -redefine the logical X11 in such a way that also points to the
+      xpm-distribution.
+      i.e.
+$  define/nolog X11 $disk2:[joukj.public.xpm.xpm.lib],decw$include
+
+    -for wxGTK you'll have to redefine SYS$SHARE to compile and run the
+         applications.
+     i.e.
+$  ass $disk2:[joukj.public.gtk.gtk.glib],-
+       $disk2:[joukj.public.gtk.gtk.glib.gmodule],-
+       $disk2:[joukj.public.gtk.gtk.gtk.gdk],-
+       $disk2:[joukj.public.gtk.gtk.gtk.gtk],-
+       $disk2:[joukj.compaq.porting_library.dist.lib],-
+       sys$sysroot:[syslib] sys$share
+
+    -At the moment you'll have to hack the [.src.common]descrip.mms file
+       to include the right location of bison/flex and sed, but i intend to
+       make this better in future.
+
+    -The following is a work-around a include file bug which occurs on some
+      versions of VMS. If you get lib$get_current_invo_context undefined
+      while linking you'll have to add
+         "lib$get_current_invo_context"="LIB$GET_CURR_INVO_CONTEXT"
+      in [.src.unix]descrip.mms to CXX_DEFINE. and recompile wxWidgets.
+
+    -Some versions of the CC compiler give warnings like
+       %CC-W-CXXKEYWORD, "bool" is a keyword in C++ .... when compiling
+       if You encounter these, replace mms by mms/ignore=warning in the
+       following
+
+  -Now build everything using one of the following
+      mms
+      mms gtk
+      mms motif
+    in the main directory of the distribution. Without an argument both wxGTK
+    and wxMOTIF are built. The libraries are built in the [.lib] directory.
+    All the samples I tried are built automatically.
+
+  -I think in general wxGTK is better maintained, so that version is my
+    first choice.
+  
+  -Note that only a few people have used wxWidgets on VMS so many problems are
+   to be expected.
+
+
+ -Many thanks for testing and reporting problems to:
+    -Walter Braeu

 
 

-Currently only the MOTIF GUI vcan be build by typing
-  MMS/MACRO=(__WXMOTIF__=1)
- in the main directory of the distribution.
- 
-It automatically makes the library in [.lib] and links the following samples
- [.samples.menu]dialogs.exe
- [.samples.menu]image.exe
- [.samples.menu]menu.exe
- [.samples.menu]minimal.exe
- 

 
 

+ -Known problems :
+   wxMOTIF :
+       -The calendar sample puts the boxes of the month and year selection on
+        top of each other.
+       -The caret sample: sometimes a non blinking caret remains in the
+        window.
+       -checklist sample: There is no way to check/uncheck since this box is
+        missing
+       -conftest sample: The boxes in the window are too small to display
+        texts with the fonts specified.
+       -controls sample: radiobox does not appear on the screen
+       -Some samples crash due to colour allocation problems
+        i.e. -drawing,image

 
 

+   wxGTK :
+       -In the calendar sample options can only be switched on and not off
+        again.
+       -image sample: after clicking "about" the colourmap is permanently
+        changed resulting in strange images
+     

 Finally :
  I like the idea of Robert Roebling that CD's with classical music should be
 send to the authors.
