Objet : Building jar files using archive member capabilities

 

Hello,

I’m trying to build JAR files in the same way as the C library files .a, using archive member capabilities. The building works fine except that the JAR file is always updated, even if its members haven’t changed. While .a files are updated only if their members have changed. Here are the rules I use to do this :

IMG_LST := $(wildcard *.BMP *.GIF *.ICO *.JPG *.bmp *.gif *.ico *.jpg)

LIB_IMG_PATH := $(imgdir)/$(shell echo "$(CURDIR)" | sed "s%.*/\([^/]*\)/lib/images\(/.*\)\{0,1\}%libimages_\1.jar%")
LIB_MBR_IMG_LST = $(IMG_LST:%=$(LIB_IMG_PATH)(%))

$(foreach __name, AR EXE IMG JAR SO, \
  $(eval LIB_$(__name)_LST = $$(sort $$(shell echo "$$(LIB_MBR_$(__name)_LST)" | sed "s,\([^ ]\)([^)]*.,\1,g"))) \
)

# The following implicit rule is used only for .a and .jar files whose members aren’t .class or .java.
(%): % | $$(@D)
@case "$@" in \
*.jar) \
  echo "$<" | egrep "\.(class|java)$$" || \
   $(ECHO) $(JAR) -$$([ -f "$@" ] && echo u || echo c)$$(echo "$(JARFLAGS)" | sed "s,[- f],,g")f $@ $< \
  ;; \
*.so) \
  ;; \
*) \
  $(ECHO) $(AR) $(ARFLAGS) $@ $< \
  ;; \
esac

# Here is an explicit rule that make libraries (.a, .jar) depend on their attached members.
$(LIB_IMG_LST) $(LIB_LST): $$(filter address@hidden, $(LIB_MBR_IMG_LST) $(LIB_MBR_LST))

Does someone have any idea to resolve this problem ?
