Hi, I am using lfs which runs kernel 2.6.34, gcc 4.1.2 and ld 2.17. For some purposes, I want to compile the 2.6.11 kernel source. After doing some configuration, I did make which issues many warnings or error messages. For some of them: ... ... ...

But, it seems that this is not really the case. To compile the 2.6.11 kernel, what do I need to adjust my system?
