Use option

g

at compile time to tell the compiler to generate symbolic debugging information in the object file.

Use option

gsplit-dwarf

to create a separate object file containing DWARF debug information. Because the DWARF object file is not used by the linker, this reduces the amount of debug information the linker must process and it results in a smaller executable file. See

gsplit-dwarf

for detailed information.

Use option

Z7

at compile time or option

debug

at link time to tell the compiler to generate symbolic debugging information in the object file. Alternately, use option

Zi

at link time to generate executables with debug information in the

.pdb

file.
