Finding an Unresolved Symbol With ld

Finding an Unresolved Symbol With ld

You can use ld to locate unresolved symbols. For example, suppose you're compiling a program, and ld tells you that you're using an unresolved symbol. However, you don't know where the unresolved symbol is referenced.

To find the unresolved symbol, enter:

ld -ysymbol file1... filen

You can also enter:

cc prog.o -Wl,-ysymbol

The output lists the source file that references symbol.
