Re: (ITS#7763) undefined references during LTO enabled build - openldap-bugs

14 Dec 2013


      Hello,
Thank you.
Markus Trippelsdorf told me in my bug report
(http://gcc.gnu.org/bugzilla/show_bug.cgi?id=59505)
what is the problem cause and how to solve it - it is not existing
support for slim-LTO-model in binutils.
AS=gcc-as AR=gcc-ar NM=gcc-nm RANLIB=gcc-ranlib did it for me for
Openldap package in Gentoo too
.
Best regards, David.

I am trying to rebuild my system with LTO enabled gcc.
Compilation of Gentoo package /net-nds/openldap-2.4.38-r1 ended with:
You cut off the trace just at the crucial line. It should say, e.g.:
ar ru librewrite.a config.o context.o info.o ldapmap.o map.o params.o rule.o
session.o subst.o var.o xmap.o version.o
ar: creating librewrite.a
Anyway, I see no build errors here. Closing this ITS. Ask for help on the
-technical mailing list.

Coul you kindly please look into it? I think that header(s) can be missing
in
source files and library(ies) at link time.
I uploaded david-kredba-20131213-build.log and
david-kredba-20131213-config.log
to your ftp server.
Thank you in advance.
