program specific LDFLAGS

[David Byron]

I'm trying to conditionally add a program-specific linker flag but I'm
having trouble.

Part of my Makefile.am looks like this:

noinst_PROGRAMS = zombie immOutTester testrunner

# Use these flags for all the programs built here
LDADD = $(top_builddir)/util/util.a $(BOOST_LIBS) ${PTHREAD_LIBS}

# testrunner needs testmain and some other things
testrunner_LDADD = $(top_builddir)/testmain/libtestmain.a $(BOOST_LIBS)
$(CPPUNIT_LIBS) $(GETOPT_LIBS) $(LDADD)

if PLATFORM_WINDOWS
    testrunner_LDADD += $(top_builddir)/minidumper/libminidumper.a
    testrunner_LDFLAGS = /ENTRY:testrunnerCRTStartup
    LIBS += version.lib
endif

Unfortunately, it doesn't look like testrunner_LDFLAGS appears anywhere in
the generated Makefile except where I assign to it above.

Instead I tried this:

if PLATFORM_WINDOWS
    testrunner_LDADD += $(top_builddir)/minidumper/libminidumper.a
/ENTRY:testrunnerCRTStartup
    LIBS += version.lib
endif

This causes me a different problem...I get an error from make (both gnu 3.80
and 3.81) like this:

Makefile:427: *** multiple target patterns.  Stop.

I also tried this:

if PLATFORM_WINDOWS
    testrunner_LDADD += $(top_builddir)/minidumper/libminidumper.a
"/ENTRY:testrunnerCRTStartup"
    LIBS += version.lib
endif

but that gives the same result.

Something else I don't understand is that using AM_LDADD above instead of
plain LDADD works fine for testrunner, but not for the other programs.
Isn't AM_LDADD considered more correct?

Thanks for your help.  I'm using automake 1.10 with the .deps patch and
autoconf 2.61.
