Andrew says

<<gcc -g -O -I/usr/openwin/include -c xv_panel_package.adb
xv_panel_package.adb:165:12: convention for "xv_get" does not permit
returning unconstrained array type
make: *** [xv_panel_package.ali] Error 1


the code causing the problem is :



 function xv_get (owner : Xv_opaque; cmd : Integer; Data : Integer;
                                                     term : Integer)
                   return Interfaces.C.Char_array;
  pragma import (C,xv_get,"xv_get");



Does anyone know why ? or how to conquer ?

This program makes no sense, since C has no concept of unconstrained
arrays. So the diagnostic makes perfect sense. To conquer it, stop
trying to return unconstrained arrays!
