Re: (ITS#7763) undefined references during LTO enabled build
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.
