I have a question regarding a GNU-make macro like this
(which I use to link a MSVC .dll):
define do_link_DLL
link $(LDFLAGS) -dll -out:$(1) -implib:$(2) \
-pdb:$(1:.dll=.pdb) -map:$(1:.dll=.map) $(3) > link.tmp
cat link.tmp >> $(1:.dll=.map)
rm -f $(2:.lib=.exp) link.tmp
endef
Using this as (in a Wireshark makefile):
wiretap.dll: $(WIRETAP_OBJ)
$(call do_link_DLL,wiretap.dll,wiretap_imp.lib, $^ $(EXTRA_LIBS))
AFAICS, if the 'link' stage fails, the rule continues to the 'cat' + 'rm' part
regardless. But from gmake's perspective all the commands succeeds (since
cat+rm returns 0). No?
How can I define my macro for gmake to quit on 'link' error?
Can the macro be written into a Perl-like:
exec("link $args") || die "link failed";
If so, how?
PS. Since I have '-verbose' in LDFLAGS, it is handy to redirect those
(error) messages into 'link.tmp' in case of a link-failure.
