Hi,
I'm trying to build a kernel module for fun, and I can't figure out a clean way to add preprocessor defines that correspond to Kconfig values. I'm trying to set CONFIG_SND_DEBUG specifically. My module has only one file, and I've tried adding #define CONFIG_SND_DEBUG as the first line in the .c file, but now I'm getting the following warning: WARNING: "__snd_printk" [/home/chris/snd/snd-foo.ko] undefined!
Without looking at your modules' course, I think that's due to you were using unexported symbol (in this case, kernel function) -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
