Makefile problems

[Bryce McKinlay <bryce at waitaki dot otago dot ac dot nz>]

The libgcj build is currently screwed up. There seem to be several 
separate problems.

Firstly, dependencies are not working. This is partly caused by the 
"--classpath" change, because one instance of "-fclasspath" in the 
Makefile did not get changed. This resulted in dependencies on 
libgcj.jar instead of the individual class files, fixed by this patch:

$(LDFLAGS) -o $@
 

However there is still a problem with native dependencies. The Makefile 
seems to get three different rules for building the .cc files:

(1)
.cc.lo:
    $(LTCXXCOMPILE) -c $<

(2)
%.lo: %.cc
    @echo '$(LTCXXCOMPILE) -c $<'; \
    $(LTCXXCOMPILE) -Wp,-MD,.deps/$(*F).pp -c $<
    @-sed -e 's/^\([^:]*\)\.o[     ]*:/\1.lo \1.o :/' \
      < .deps/$(*F).pp > .deps/$(*F).P; \
    tr ' ' '\012' < .deps/$(*F).pp \
      | sed -e 's/^\\$$//' -e '/^$$/ d' -e '/:$$/ d' -e 's/$$/ :/' \
        >> .deps/$(*F).P; \
    rm -f .deps/$(*F).pp

(3)
$(nat_files) $(x_nat_files): %.lo: %.cc
    @echo '$(LTCXXCOMPILE) -MD -MT $@ -MF $(@:.lo=.pp) -c -o $@ $<'; \
    $(LTCXXCOMPILE) -MD -MT $@ -MF $(@:.lo=.pp) -c -o $@ $<
    @-mv $(@:.lo=.pp) $(@:.lo=.d)


The 1st and second rules are put in by automake while the 3rd is our own 
rule in Makefile.am. It used to be that the second rule got used, but 
when the 3rd one was added it got used instead because it is more 
specific. But now for some reason the first one is being used, and 
proper dependencies dont get generated. Anyone know what caused this to 
change?

Finally, "make install" is not working properly (this one at least seems 
to have broken in the last few days). libgcj.so.2.0.0 simply does not 
get installed unless I delete it from the installation directory first! 
All the other libraries do get installed correctly. Ugh. I have no idea 
what is going on here. libtool I guess ;-(
