[OpenAFS-devel] configure error on fedora 9

[zhu shi song]

Dear lists,
I want to build openafs-1.5.55 on my fedora9 machine. But when I ran configure, it prompted the following erros:

checking your OS... configure: WARNING: No usable linux headers found at /usr/src/linux so disabling kernel module
linux
checking your AFS sysname... configure: error: Couldn't guess your Linux version. Please use the --with-afs-sysname option to configure an AFS sysname.

How can I fix the errors?

tks
zhu
