By default, the Windows 98 DDK Checked Build Environment does not build symbol files that contain line number information. To use WDEB98/RTERM98 source-level debugging, the symbol file must contain line number information.


To build symbol files that contain line-number information, modify the following files:
  1. Modify the Makefile.def file in the Win98\Inc folder to cause the linker to use the correct linker options to build a .map file with line-number information.
  2. Use the Mapsym.exe file, once the correct link options are used, to build a .sym file with line-number information that matches your .sys file. Follow these steps:
    1. In your SOURCES file for the driver you are building, add the following line:
    2. Edit the DDK\Inc\Makefile.def file and make the following changes:

      Change the line that reads as follows (should be line 1138)
      to the following:
      Change the line that reads as follows (should be line 1276)
      LINKER_DBG_TYPE = -debugtype:both
      to the following:
      LINKER_DBG_TYPE = -debugtype:MAP,COFF
    3. Rebuild the driver. You should see a (driver_Name).map file in the Win98ddk\Lib\i386\Checked folder. You can check for line-number information by opening the .map file and checking to see if it contains line numbers near the bottom of the file.
    4. With line-number information, you can specify a code search path in RTERM98. You should then see the source window open when a breakpoint is hit in the driver.


See the Windows 98 DDK for more information on building and debugging drivers.
