Hi Dave,

liboctinterp_la_LDADD is not defined.

from Makefile.am
--------------------------------------------------
liboctinterp_la_LDFLAGS =3D -release $(version) $(NO_UNDEFINED_LDFLAG)

OCTINTERP_LINK_DEPS =3D \
  $(RLD_FLAG) \
  ../liboctave/liboctave.la \
  ../libcruft/libcruft.la \
  ../libgnu/libgnu.la \
  $(FFTW_XLDFLAGS) $(FFTW_XLIBS) \
  $(HDF5_LDFLAGS) $(HDF5_LIBS) $(Z_LDFLAGS) $(Z_LIBS) \
  $(OPENGL_LIBS) $(X11_LIBS) $(CARBON_LIBS) \
  $(READLINE_LIBS) $(TERM_LIBS) \
  $(LIBGLOB) \
  $(LAPACK_LIBS) $(BLAS_LIBS) \
  $(LIBS) \
  $(FLIBS)

liboctinterp_la_LIBADD =3D $(OCTINTERP_LINK_DEPS)
----------------------------------------------

the LIBS are in the format
LAPACK_LIBS=3D'-llapack'


It looks right to me, but my understanding of=20
automake matter is still very basic

Thanks
Marco
