• Type: Improvement
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.6.0
• Affects Version/s: Lustre 2.4.0
• Labels: build patch
• Environment: Debian Wheezy with Lustre patched RedHat Kernel 2.6.32-279.5.1.el6

Description

Compiled executable Lustre files such as:
lst, lstclient, loadgen, lustre_rsync, lctl, lfs, debugctl and
ptlctl are linked against libtinfo.so.5 and libncurses.so.5, however
none of the library's symbols are used.

Same issue with multiop which is linked against librt.so.1, however uses none of the library's symbols, and liblustre.so which is linked against libz.so.1 and uses none of the library's symbols.

Additionally, a Debian build package run (e.g. make debs or dpkg-buildpackage)
is creating a bunch of warning repetitions such as

dh_clean: No compatibility level specified in debian/compat
dh_clean: This package will soon FTBFS; time to fix it!
..

I will provide a patch to fix these issues.
