$(wildcard ) evaluation

[Rinehart, Raleigh]

I’m having a small issue with my builds, specifically the way a variable is getting expanded.  I suspect it is due to make’s caching of the directory contents.

 

In my makefile I have a variable defined like this:

 

outfiles = $(wildcard *.out)

 

which gets used later in the makefile like this:

 

define artifacts

@echo moving build artifacts for target $(1)

@$(MD) output/$(1)

@echo --- .out files are = $(outfiles)

   -$(CP) $(outfiles) output/$(1)

   …

endef

 

 

The artifact macro is in turn called by a build rule as follows:

 

release:

            @echo -----Release build-----

            @$(MAKE) -f $(makefile_name) clean OBJECTONLY=y

            @$(MAKE) -f $(makefile_name) $(releasedefs)

            $(call artifacts,$@)

 

The default target builds the .out

#build phoenix base code

projectA.out: ../project/src/main.o \

             $(libraries) \

             sharedlibs \

             version

            @echo building $@

            @echo LD $@ $<

            @$(LD) -Tlink_ram_asic.ld -Map projectA.map -o $@ $< --start-group $(APPLIBS) $(LIBS) --end-group

 

Now when I run something like “make release” the out files don’t get copied because the wildcard variable seems to be getting expanded immediately instead of deferred.

The echo output is empty --- .out files are =

So I am missing something completely obvious or what?

 

 

thanks,
