Kconfig options and make command line

Kconfig options and make command line

[Peter Senna Tschudin]

I was trying to compile the file:

drivers/staging/rtl8723au/core/rtw_ap.c

but

$ make drivers/staging/rtl8723au/core/rtw_ap.o

doesn't work as there is no Makefile at core directory.

Doing:

$ make drivers/staging/rtl8723au/

doesn't work also as rtw_ap.c is only compiled under certain Kconfig
conditions due this line at the Makefile:

r8723au-$(CONFIG_8723AU_AP_MODE) += core/rtw_ap.o

So is there a way to compile rtw_ap.o by just passing arguments to make?

Sorry for the noise.

$ make allyesconfig drivers/staging/rtl8723au/

does the trick.

that seems like overkill, why not just enable the CONFIG_8723AU_AP_MODE
setting?

Not only is it overkill, the resulting .o file can't be modprobed into a kernel.

Enabling the Kconfig variable is a better answer.
