[Pvfs2-users] compiling kernel module of pvfs2.7.1pre and RHEL4 kernel 2.6.9-55 - red hat

[Michael Will]

Thanks for your prompt respone. The architecture I am working on is 
amd64 aka x86_64,  opteron/xeon servers with
redhat enterprise 4 update 5 and update 6.

For the pvfs-2.7.0 indeed the make distclean helps with the initial 
problem, so something must be included in the archive that
was not supposed to be there. I uploaded my copy as I downloaded it on 
http://www.quickfilepost.com/download.do?get=a8811c0c7a4d56eb16dd7d655d4cb858
and my build-tree after prepare ; ./configure 
--with-kernel=/usr/src/kernels/linux-2.6/ --disable-kernel-aio  ; make kmod
is on 
http://www.quickfilepost.com/download.do?get=4e30a6ec25ee4997f3bbd044605eb28d

76cb0e1b921b908f16cb24de451e7ce4  pvfs-2.7.0.rhel4u5.tar.gz
99e7680e82b692f699b5a295b31989c8  pvfs-2.7.0.tar.gz

However the kmod still complains about *** Warning: 
"class_device_destroy" [/root/pvfs-2.7.0/src/kernel/linux-2.6/pvfs2.ko] 
undefined!
and pvfs2-config.h has #define HAVE_KERNEL_DEVICE_CLASSES 1 defined, 
which prevents loading the module, regardless
of --disable-kernel-aio.

I will next try to give pvfs-2.6.3 a spin...
