#2553: Cactus' link command used CPPFLAGS and CXXFLAGS

Reporter: Roland Haas Status: new Milestone: Version: development version Type: bug Priority: minor Component: Cactus

Cactus link line in make.configuration looks like this right now:

``` $(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) ```

ie it passed `$(CPPFLAGS)` and `$(CXXFLAGS)` to `$(LD)`. While we do normally set `LD` to the same as `CXX` this is not always correct, eg if one would like to use `g++` for C++ files but link with `nvcc`.

Neither one of these options is required or should be there since `$(LD)` does not compile anything at all. Any subset of options from `$(CPPFLAGS)` or `$(CXXFLAGS)` that may be needed (eg `-fopenmp` should be set in `$(LDFLAGS)`).
