Why am I linking to an installed library?

[Bruce Korb]

Hi,

On x86 Linux:  i686-pc-linux-gnu

I just made an extension to the shared library in my pet project.
The older version has been installed in /usr/lib via rpm and
in /usr/local/lib via "make install".  /etc/ld.so.conf seems a
bit over the top, but looks like this:

> /usr/X11R6/lib/Xaw95
> /usr/X11R6/lib/Xaw3d
> /usr/X11R6/lib
> /usr/i486-linux/lib
> /usr/i486-linux-libc5/lib=libc5
> /usr/i486-linux-libc6/lib=libc6
> /usr/i486-linuxaout/lib
> /usr/i386-suse-linux/lib
> /usr/local/lib
> /usr/openwin/lib
> /opt/kde/lib
> /opt/kde2/lib
> /opt/kde3/lib
> /opt/gnome/lib
> /opt/gnome2/lib

When I rebuild autogen, .libs/lt-autogen winds up pulling
/usr/lib/libopts.so.25.0.1 despite the fact the current
project has a .libs/libopts.so.25.1.0 version.  So, here's
the stuff from the Makefiles:

Makefile (configured values):
> LIBGUILE_CFLAGS =
> LIBGUILE_LIBS = -lguile -lguile-ltdl -lqthreads -lpthread -lcrypt -lm
> DYNAMIC_AG = -export-dynamic

Makefile.am:
> GEN_CSRC   = opts.h directive.h expr.ini expr.h proto.h pseudo-fsm.h
> nodist_autogen_SOURCES = ag.c
> autogen_SOURCES = $(GEN_CSRC)
> autogen_LDADD   = $(top_builddir)/autoopts/libopts.la $(LIBGUILE_LIBS)
> autogen_LDFLAGS = $(DYNAMIC_AG)
> autogen_CFLAGS  = $(LIBGUILE_CFLAGS)

If I hand edit the script "autogen" to contain:

> LD_LIBRARY_PATH=#{top_builddir}/autoopts/.libs
> export LD_LIBRARY_PATH

then it works correctly.  If I do not do that, it binds to the previous
library version in /usr/lib.  Everything is also fine if I:

# rpm --erase autogen

What's wrong?  :-)  Thank you!  Regards, Bruce
