The Makefiles in the four subdirectories (into which the source is
divided) contain the (new) lines
SONAME=$(LIBBASE).so.0
where LIBBASE is something different for each subdirectory. Then in
the top-level Makefile, the line
SO_OPTS = -fPIC --shared
is changed to
SO_OPTS = -fPIC --shared -Wl,--as-needed
and in the top-level Makefile.dynamic,
$(SO_LIBNAME): $(A_LIBNAME)
$(CXX) $(SO_OPTS) $(A_LIBNAME) $(OBJS) -o $(SO_LIBNAME)
$(NTLLFLAGS) $(LIBFLAGS)
was changed to
(SO_LIBNAME): $(A_LIBNAME)
$(CXX) $(SO_OPTS) -Wl,-soname,$(SONAME) $(A_LIBNAME) $(OBJS) -o
$(SO_LIBNAME) $(NTLLFLAGS) $(LIBFLAGS)
These changes were made by the Debian guy, but apparently cause the
build to fail on the OpenSolaris machine Hawk. As far as I am
concerned everything worked before these changes and after (on my
linux machines) but if someone who sounds as if he knows what he is
talking about says "this is the right way to do it" I tend to believe
them provided that the change still works for me.
At the time this change was made to eclib "upstream" (in June 2011) I
did ask David Kirby whether this looked ok for Solaris, but he did not
reply, and it is only since December that I have trying to get the
eclib version included in Sage upgraded -- not for this technical
change of course, but for genuine reasons.
