<p>Cactus link line in make.configuration looks like this right now:</p>
<div class="codehilite"><pre><span></span><span>$(LD) $(CREATEEXE)$(OPTIONSEP)"$(call TRANSFORM_DIRS,$@)" $(CPPFLAGS) $(CXXFLAGS) $(LDFLAGS) $(EXTRAFLAGS) "$(call TRANSFORM_DIRS,$(TOP)/datestamp.o)" $(BEGIN_WHOLE_ARCHIVE_FLAGS) $(CACTUSLIBLINKLINE) $(END_WHOLE_ARCHIVE_FLAGS) $(GENERAL_LIBRARIES)</span>
</pre></div>
<p>ie it passed <code>$(CPPFLAGS)</code> and <code>$(CXXFLAGS)</code> to <code>$(LD)</code>. While we do normally set <code>LD</code> to the same as <code>CXX</code> this is not always correct, eg if one would like to use <code>g++</code> for C++ files but link with <code>nvcc</code>. </p>
<p>Neither one of these options is required or should be there since <code>$(LD)</code> does not compile anything at all. Any subset of options from <code>$(CPPFLAGS)</code> or <code>$(CXXFLAGS)</code> that may be needed (eg <code>-fopenmp</code> should be set in <code>$(LDFLAGS)</code>).</p>
