Package: lustre-source
Version: 1.6.6-1
Severity: normal
For some Lustre clients, I would like to run a standard lenny with
a patchless Lustre installation.
I started with the Debian package lustre-source-1.6.6 from experimental,
but I get into two problems when compiling. I tried to fix these, and
the resulting modules do work. However I am not sure, whether
especially the second fix is a good solution.
Here the details:
System: lenny, with 2.6.26-1-amd64 kernel
kernel source: linux-source-2.6.26 (2.6.26-13)
Lustre: lustre-source 1.6.6-1 from experimental
Building lustre using "module-assistant build lustre"
1) problem 1 (llite_mmap.c):
CC [M] /usr/src/modules/lustre/lustre/llite/llite_mmap.o
/usr/src/modules/lustre/lustre/llite/llite_mmap.c:626: error: unknown field
'populate' specified in initializer
/usr/src/modules/lustre/lustre/llite/llite_mmap.c:626: error: 'll_populate'
undeclared here (not in a function)
This looks like an easy thing to fix, just putting the populate field
after the next one. I'll attach a patch for this. If I fix it this way,
compilation continues,
but then stops here:
2) problem 2 (lprocfs_status.c):
CC [M] /usr/src/modules/lustre/lustre/obdclass/lprocfs_status.o
/usr/src/modules/lustre/lustre/obdclass/lprocfs_status.c: In function
'lprocfs_remove':
/usr/src/modules/lustre/lustre/obdclass/lprocfs_status.c:318: error: implicit
declaration of function 'LPROCFS_WRITE_ENTRY'
/usr/src/modules/lustre/lustre/obdclass/lprocfs_status.c:340: error: implicit
declaration of function 'LPROCFS_WRITE_EXIT'
Just to get it compiled, I have #define'd these to functions to (0) in
lprocfs_status.h,
and then I get a lustre-modules-2.6.26-1-amd64_1.6.6_amd64.deb. The resulting
modules
do work on a test system.
It looks like the #ifdef HAVE_PROCFS_DELETED is not found upstream, any hint
why
we need this in Debian?
Kind regards, Ralf
