hi I'm sorry to disturb you for that problem which may be a beginner pb, but i have read lot of doc, and i still dont understand: trying to build the kernel menuconfig program, I saw the message that there is lacking symbols , but i have installed the good library in /usr/lib and it still doesn't find the good symbols in the library, so i think we should add the library in the library checked by gcc when linking a program, but i don't find in any doc, where to add it? can you help me, thank you.
