Generating map and list files

Edit online

Assembler listing and map files are useful tools for debugging with the KDB kernel debugger.

To create the assembler list file during compilation, use the -qlist option. Also use the -qsource option to get the C source listing in the same file. To create the assembler list file with these options, type the following:

cc -c -DEBUG -D_KERNEL -DIBMR2 demokext.c -qsource -qlist

In order to obtain a map file, use the -bmap:FileName option for the link editor. The following example creates a map file named demokext.map:

ld -o demokext demokext.o -edemokext -bimport:/lib/syscalls.exp \
-bimport:/lib/kernex.exp -lcsys -bexport:demokext.exp -bmap:demokext.map
