Automake problem creating library only containing other libraries

[Joris Esch]

Hi:

We experencienced some problems creating a libtool library. The library
will be used as a collection of other useful libtool libraries.

We had the following Makefile.am
-------
noinst_LTLIBRARIES    = libfood.la
libfood_la_LIBADD          = $(top_builddir)/src/sugar/libsugar.la \

$(top_builddir)/srs/milk/libmilk.la
-------

We got around it by creating an EMPTY dummy file libfoodhack.cpp
and by changing Makefile.am
-------
noinst_LTLIBRARIES     = libfood.la
libfood_la_SOURCES       = libfoodhack.cpp
libfood_la_LIBADD          = $(top_builddir)/src/sugar/libsugar.la \

$(top_builddir)/srs/milk/libmilk.la
-------

We use automake version 1.4.
It seemed like some variables or macros where not correctly set in the
generated Makefile (Specifically $(LINK) ). This was solved by adding a
.cpp file to the dependency list.

Is there a more elegant way to solve this problem?

Thank you,
