Hello, I'm building OS via LFS similar mode. Now I'm trying to build kernel 2.6.31.5, then upon it building application packages. Now my trouble is on those header files generated by kernel build option - "header_install". Until now I met 2 problems: 1) 2.6.31.5 generated several include sub folders: asm, asm-generic, drm, linux, mtd, rdma, scsi, sound, video, xen. After I copied them into /usr/include, I found some packages like cdrtools, eject, hdparm, util-linux can not be compiled, because in scsi/scsi.h line 145 "u8" is undefined. I checked it, it seems that u8 definition is for kernel build not for application. 2) perl (5.8.8) and raidtools (1.00.3) need "asm/page.h", but there's none generated. Previously, I built my system under kernel 2.6.27.7. There's no above problems. Could some kindly answer my questions? Thanks a lot.
