Hi,

i added the stuff to pe linker script "pe.sc" as recommended:

--- binutils-2.16.1/ld/scripttempl/pe-orig.sc   2004-12-01 00:54:53.000000000 
+0100
+++ binutils-2.16.1/ld/scripttempl/pe.sc        2005-09-30 22:39:21.843750000 
+0200
@@ -270,5 +270,10 @@
   {
     *(.debug_ranges)
   }
+
+  .gnu_debuglink ${RELOCATING+BLOCK(__section_alignment__)}
${RELOCATING+(NOLOAD)} :
+  {
+    *(.gnu_debuglink)
+  }
 }
 EOF 

-----------------

and rebuilt the whole thing.
It didnt work. Same result:

-------------

Sections:
Idx Name          Size      VMA       LMA       File off  Algn
  0 .gnu_debuglink 00000018  00000000  00000000  00000268  2**2
                  CONTENTS, READONLY, DEBUGGING
  1 .text         001f2528  00401000  00401000  00000600  2**4
                  CONTENTS, ALLOC, LOAD, READONLY, CODE, DATA
   ....


I verified the change after rebuild: ld\i386pe.*

--------------- snip -----

  ....

  .debug_ranges BLOCK(__section_alignment__) (NOLOAD) :
  {
    *(.debug_ranges)
  }
  .gnu_debuglink BLOCK(__section_alignment__) (NOLOAD) :
  {
    *(.gnu_debuglink)
  } 

------------------------------------

Seems it is not an easy fix...
What can i do further?

Regards
