How to make configure script generate the right LIBS for the plugins in the
configure.ac file ?
Your complaint may be related to 'libtool' and not 'autoconf' (look
for the libtool list). Since your desire is not necessarily portable,
libtool currently applies all dependencies at link time. Some OS
distributions modify their libtool to work differently.
There is also a possibility that your complaint is related to
'automake' rather than 'autoconf' (look for the automake list). By
default, automake applies all libraries obtained from configure's LIBS
variable. By taking care with how LIBS is formulated, and using more
specific automake code you can do something like this (example taken
from my own package):
In Makefile.am:
# TIFF coder module
coders_tiff_la_SOURCES = coders/tiff.c
coders_tiff_la_CPPFLAGS = $(MODULE_EXTRA_CPPFLAGS)
coders_tiff_la_LDFLAGS = $(MODULECOMMONFLAGS)
coders_tiff_la_LIBADD = $(LIBMAGICK) $(LIB_TIFF) $(LIB_JPEG) $(LIB_ZLIB)
With the various variables being figured out by the configure script.
This allows the libraries applied while linking your module to be more
specific. However, you must take care because if you want your
software to compile and work on systems which don't allow unresolved
symbols (e.g. Win32 & AIX) all of the libraries necessary to resolve
all symbols must be applied.
