Thanks Bruno. I was talking to the OpenLDAP folks. Their module has 3 problems, so it was the one I looked at first. They knew the reordering problem. They said it was libtool. They said in the past they used to provide a hacked libtool to work around it. They said they stopped hacking libtool because it needed to happen too frequently (each update?). Jeff

I don't know. You would need 1) to find the specification(s) of -runpath. It must be recent: a GNU ld from 2015 does not support it, 2) to determine (using "gcc -v") whether it's libtool, gcc, or the linker which does the reordering. The specification of DT_RUNPATH appears to be in [1]. Bruno [1] http://www.sco.com/developers/gabi/latest/ch5.dynamic.html#shobj_dependencies
Handling of runpaths
Hi Everyone, I noticed my runpaths are re-ordered in libraries like libgettextsrc.so, libtextstyle.so, libgettextpo.so, libgettextlib.so, libgettextlib.so, libintl.so and libunistring.so. For example, I use LDFLAGS of: -Wl,-runpath,'$ORIGIN/../lib' -Wl,-runpath,$(prefix)/lib -Wl,--enable-new-dtags Later, when I audit the runpaths, I see the following (when building OpenSSH and dependencies for /opt/ssh): RUNPATH: /opt/ssh/lib:$ORIGIN/../lib Notice the ordering has been changed. Is the re-ordering of runpaths expected? Jeff
