[Lustre-discuss] Compiling lustre 1.8.X on Ubuntu LTS 10.04

[Ramiro Alba Queipo]

Hi everybody,

I would like if anybody is trying to compile lustre 1.8.X on Ubuntu LTS
10.4/Debian testing(squeeze), and know your opinion/comments on what
I've got:


I've been using lustre 1.8.1.1 with RedHat5 kernel 2.6.18-128.7.1 on
Ubuntu LTS 8.04 both serves and clients, but now I would like to upgrade
to the recent Ubuntu LTS 10.04.
When I try to compile lustre 1.8.1.1 on Ubuntu 10.04 (gcc-4.4 and libc6
2.11.1 instead gcc-4.2 and libc6-2.7.10 on Ubuntu 8.04) and once
suppressed all references in to "-Werror" in configure script (I tried
--disable-werror, but it did not work), I finally got:

In file included from src/init.c:70:
./include/xtio.h:140: error: conflicting types for 'preadv'
/usr/include/sys/uio.h:66: error: previous declaration of 'preadv' was
here
./include/xtio.h:259: error: conflicting types for 'pwritev'
/usr/include/sys/uio.h:78: error: previous declaration of 'pwritev' was
here
make[2]: *** [src/init.o] Error 1
make[2]: Leaving directory
`/home/packages/lustre/1.8.1.1/lustre-1.8.1.1/libsysio'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory
`/home/packages/lustre/1.8.1.1/lustre-1.8.1.1'
make: *** [all] Error 2

Same result if using gcc-4.1 or gcc-4.3.

When I try the recent lustre-1.8.3 and RedHat5 kernel 2.6.18-164.11.1 I
get far less warnings and it do compiles. 

Most of the warnings are of type:

/home/packages/lustre/1.8.3/lustre-1.8.3/lustre/mds/mds_join.c:243:
warning: format '%u' expects type 'unsigned in
t', but argument 11 has type 'long unsigned int'

except one:

        else rm -f ".deps/liblov_a-lov_pack.Tpo"; exit 1; \
        fi
