XmVERSION-sensitive unresolved symbols in lwlib-Xm.c

When building xemacs-21.5 I got some unresolved symbols when linking temacs, originating in lwlib-Xm.c. For example xmComboBoxWidgetClass. It turns out that these are all dependent on XmVERSION > 1, and if I added #define XmVERSION 1 to the file (after including headers) the problem went away. Perhaps this is a brokenness of my system (SunOS 5.8) in that the shared library does not match the header files. But anyway, perhaps there could be an autoconf test that tries to compile and link a small program containing #if defined (LWLIB_WIDGETS_MOTIF) && XmVERSION > 1 foo = xmComboBoxWidgetClass; #endif and if this fails, assumes that XmVERSION == 1 despite what the system headers may say. -- Ed Avis <ed.avis(a)kbcfp.com&gt;
