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:
- 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.
- 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:
- In your SOURCES file for the driver you are building, add the following line:
- 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)
to the following:
LINKER_DBG_TYPE = -debugtype:both
LINKER_DBG_TYPE = -debugtype:MAP,COFF
- 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.
- 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.
