[buug] How to tell cc compiler to put -o object file freeBSD_main.o in my ./freeBSD directory ? Or how to tell ld linker to search freeBSD_main.o in my home directory /home/Liu/AOC ?

[Liu Wang]

Any help would be appreciated !

I am writing a FreeBSD driver module.
How to tell cc compiler to put -o object file freeBSD_main.o in my ./freeBSD directory ?
Or how to tell ld linker to search freeBSD_main.o in my home directory /home/Liu/AOC ?
