There is. The libraries in the subdirectories should be built as
libtool convenience libraries. Each corresponding Makefile.am should
look a bit like this:
noinst_LTLIBRARIES = libsubdirectory.la
libsubdirectory_la_SOURCES = src1.c srcn.c
If you only want old style static ar archives, you must add:
libsubdirectory_la_LDFLAGS = -static
To combine a bunch of these in a different directory, the Makefile.am
looks something like this:
lib_LTLIBRARIES = libcombine.la
libcombine_la_SOURCES = comb1.c combn.c
libcombine_la_LIBADD = $(top_builddir)/sub1/libsubdirectory.la \
$(top_builddir)/subn/libanothersubdir.la
Again you can also add:
libcombin_la_LDFLAGS = -static
if you only want ar archives.
Cheers,
Gary.
