autofei

after install redhat 8.0 , into /usr/src

[root@autofei src]# ls
linux-2.4  linux-2.4.18-14  redhat

[root@autofei redhat]# ls
BUILD  RPMS  SOURCES  SPECS  SRPMS

what is the function of redhat directory?

show error info, maybe link wrong, but i did

# cd /usr/include/
# rm -r asm linux scsi
# ln -s /usr/src/linux/include/asm-i386 asm
# ln -s /usr/src/linux/include/linux linux
# ln -s /usr/src/linux/include/scsi scsi

how to fix this problem?

下载了2.6的内核，还是提示如下错误，请版主大人指教了！实在是想不出来什么问题了，谢谢！
