Hello, I had no internet for few days and couldn't check the links you sent (now I'll do it as soon as possible), but I would like to thank you Christian for response and tips about upper bound, lower bound and how to understand dependencies and selects. There are many other attributes which I'm not sure of semantics, but I try to understand it testing make menuconfig and watching differences in generated .config or checking mconf code. I am very appreciate for your help. It would be nice to have semantics explained in documentation btw Filip -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
