[Pvfs2-users] configure: error: The kernel source tree does not appear to be 2.6

[Elaine Quarles]

After running configure you need to continue with the steps given in section
5.2 and following of the quickstart instructions
(http://orangefs.org/documentation/releases/current/doc/pvfs2-quickstart/pvf
s2-quickstart.php#SECTION00062000000000000000). Running "make kmod" will
build the kernel module.

Hello,

 

i actually did:

 

sudo ./configure --with-kernel=/usr/src/kernels/2.6.18-194.17.1.el5-x86_64

 

and then it outputted:

 

----------------------------------------------------------------------

***** Displaying PVFS Configuration Information *****

------------------------------------------------------

PVFS2 configured to build karma gui               :  no

PVFS2 configured to perform coverage analysis     :  no

PVFS2 configured for aio threaded callbacks       : yes

PVFS2 configured to use FUSE                      :  no

PVFS2 configured for the 2.6.x kernel module      : yes

PVFS2 configured for the 2.4.x kernel module      :  no

PVFS2 configured for using the mmap-ra-cache      :  no

PVFS2 will use workaround for redhat 2.4 kernels  :  no

PVFS2 will use workaround for buggy NPTL          :  no

PVFS2 server will be built                        : yes

 

PVFS2 version string: 2.8.1

---------------------------------------------------------------------

 

(Previously i had tested: 

[pvfs-2.8.1]$ sudo ./configure
--with-kernel=/usr/src/redhat/BUILD/kernel-2.6.35.7custom

OUTPUT:configure: error: The kernel source tree does not appear to be 2.6)

 

What shall i do next?

 

In the quick start guide says: "The module itself is the file pvfs2.ko in
subdirectory src/kernel/linux-2.6 in your build tree"

In my folder "/usr/pvfs-2.8.1/src/kernel/linux-2.6" there is no file named
pvfs2.ko or any file created  today.

Tha only file that is modified is the "Makefile" in that specific folder.

So what about the next step? Cause i can't not "insmod" anything.

 

Thanks, in advance

 

ps. I don't know if the machine is a cluster
