.jpg and .gif

[alice dubois]

Hello,

 WidgetsDemo uses tvt.jpg. When I run WidgetsDemo.sh the image doesn't 
 appear
  and an exception is caught:
 java.lang.NullPointerException
         at java/awt/ImageFileProducer.startProduction(27)
         at java/awt/Image.loadImage(189)
         at java/awt/Image.getHeight(145)
         at WidgetsDemo.paint(381)
         at java/awt/Window.update(305)
         at java/awt/PaintEvent.dispatch(51)
         at java/awt/EventDispatchThread.show(127)
         at java/awt/WMEvent.dispatch(52)
         at java/awt/EventDispatchThread.run(38)

 If I put a .gif instead of the .jpg, everything is correct.
 Why ?

 To make it working , here is what I have done:
 In configure:
 ...
   # Accept the important Cygnus configure options, so we can diagnose 
 typos.


   case "$ac_option" in

   --jpeg=*)                    #added
     jpeg="$ac_optarg" ;;       #added

   -bindir | --bindir | --bindi | --bind | --bin | --bi)
     ac_prev=bindir ;;
   -bindir=* | --bindir=* | --bindi=* | --bind=* | --bin=* | --bi=*)
     bindir="$ac_optarg" ;;
 ...
 if test "$have_x" = "yes" ; then
 make_output="$make_output \
 libraries/clib/awt/Makefile \
 "
 JAVA_LIBRARIES="$JAVA_LIBRARIES \
 ./../libraries/clib/awt/libawt$LIBEXT \
 $jpeg/libjpeg.a \                         #added
 "
 fi


 if test "$dynamic_libraries" = "yes" ; then
         NOSHAREDLIBS="-L../kaffevm -lkaffevm $VM_LIBRARIES $STD_LIBRARIES"
         KAFFE_LIBDEP=""
 else ....

 Like that I can say where is my libjpeg.a when I run configure with the 
 option --jpeg=DIR.

 Is it correct ?

 I don't understand where libgif.a is found. It must be found somewhere, 
 mustn't it ?

 Thanks,

 Alice
