Peter,
Was that really the whole link line? No libraries included at all? The
libtiff configure script is supposed to try adding -lz if zip support is
enabled and nothing else is provided in the config.site script.
The rule in Makefile.in seems to be:
DARWINdso: ${OBJS}
${CC} -dynamiclib -undefined error \
-install_name libtiff.@DSOSUF@ \
-o libtiff.@DSOSUF_VERSION@ ${OBJS} \
@LIBJPEG@ @LIBGZ@ @MACHDEPLIBS@
rm -f libtiff.@DSOSUF@
if [ @DSOSUF_VERSION@ != @DSOSUF@ ] ; then \
@LN@ @LN_S@ libtiff.@DSOSUF_VERSION@ libtiff.@DSOSUF@; \
fi
touch $@
This should include any jpeg, and libz library in the link command. The
configure rules try to set LIBGZ if ZIP is enabled. Did you enable zip
support by including it in config.site or just by adjusting tiffconf.h?
If you just modify tiffconf.h then you will have to manually include the
libz. Editing the expanded DARWINdso target in your libtiff-3.6.1/libtiff/Makefile
to include -lz should fix the problem.
But the "proper" way of turning on zip support is to enable it in config.site
by uncommenting the ZIP="yes" line. This sets things up so the configure can
try to include the supporting library.
Best regards,
