Re: [Autogen-users] FW: problem with auto-opts definition element . . .

Hi,

The stuff is *SUPPOSED* to be linked with -Wl,-R/usr/local/lib and that is
*SUPPOSED* to force ldd to show /usr/local/lib/libopts.so.33 ahead of
anything else in the /etc/ld.so.conf file.  It has never been effective enough.

The name of the 64 bit library directory under /usr/local in a hybrid
environment is the subject of disagreement.  I think /usr/lib64
implies /usr/local/lib64, but I am not a distro maintainer.  You'd
have to devise a scheme for deciding that all distros would agree on.
Good luck.  Meanwhile, my ld.so.conf contains:

> /usr/X11R6/lib64
> /usr/X11R6/lib
> /usr/local/lib64

so "lib64" is always looked at before plain "lib" and
both /usr/local directories are searched before /lib* and /usr/lib*.
That works for me.  Well, as long as I don't have a privately built
library that gets upgraded to be more recent in /usr/lib64.
At that point, I got to choose whether to break gcc or break my
pre-release autogen.  I chose obliterating /usr/local and starting
over. :)  Sorry it isn't any easier.

Exactly right.  Unless and until there is a way to select lib directory
names based on architecture for multi-architecture environments.
