The Makefile.am file that I'm using to generate an archive library for a project I'm working on looks like this:
---
AM_CXXFLAGS = -I$(top_srcdir) -I.
lib_LIBRARIES = libflarray.a
libflarray_a_SOURCES =
FLArray.cc \
FLArray.hh \
FLSorted.cc \
FLSorted.hh---
The output from make clean ; make in this directory after the Makefile has been generated is this:
---
steely:~/src/paul/cvs/cbrc/C++/utils/FLArray cjcollier$ make clean
test -z "libflarray.a" || rm -f libflarray.a
rm -f *.o core *.core
steely:~/src/paul/cvs/cbrc/C++/utils/FLArray cjcollier$ make

then mv -f ".deps/FLArray.Tpo" ".deps/FLArray.Po"; \
else rm -f ".deps/FLArray.Tpo"; exit 1; \
fi

ar cru libflarray.a FLArray.o FLSorted.o
ranlib libflarray.a
ranlib: warning for library: libflarray.a the table of contents is empty (no object file members in the library define global symbols)

And when I try to link against that .a file, I get this error:
---
steely:~/src/paul/cvs/cbrc/C++/classifiers/learnedWeightKNN/test cjcollier$ make
g++ -I../../.. -I. -g -O2 -o PSORT+WoLFpredictForCJ PSORT+WoLFpredictForCJ.o ../../../utils/FLArray/libflarray.a ../../../utils/perlish/libperlish.a ../../../classifiers/libclassifiers.a ../../../classifiers/learnedWeightKNN/liblearnedWeightKNN.a
ld: warning empty table of contents: ../../../utils/FLArray/libflarray.a (can't load from it)

Can someone help me figure out how to generate a good archive library? I'm new to this.
Thanks in advance.
