funtions in rule ?

[Mirko Viviani]

Ciao.

# gmake --version
GNU Make version 3.78.1, by Richard Stallman and Roland McGrath.
Built for i386--freebsd3.4

In this rule I need to use patsubst and filter but I'm not able to get it
working.
I've found nothing in the make.info about using function inside a rule
so I don't know if there is a way to get it working or if I'm wrong.

$(DUMMY_FRAMEWORK_FILE): $(DERIVED_SOURCES) $(C_OBJ_FILES) $(OBJC_OBJ_FILES) 
$(SUBPROJECT_OBJ_FILES) $(OBJ_FILES) GNUmakefile
        if [ "$(OBJC_OBJ_FILES)" != "" ]; then objcfiles="$(OBJC_OBJ_FILES)"; \
        fi; \
        if [ "$(SUBPROJECT_OBJ_FILES)" != "" ]; then objcfiles="$$objcfiles 
$(SUBPROJECT_OBJ_FILES)"; \
        fi; \
        if [ "$$objcfiles" = "" ]; then objcfiles="__dummy__"; \
        fi;\
        if [ "$$objcfiles" != "__dummy__" ]; then \
          for f in $$objcfiles; do \
            sym=`nm -Pg $$f`; \
            sym=$(patsubst __objc_class_name_%,%,$$sym); \
                echo $$sym; \
          done; \
        fi;

This is the output of the $$sym and the __objc_class_name prefix is still
there:

NSLog U NSZeroPoint C 00000008 NSZeroRect C 00000010 NSZeroSize C 00000008 
_GLOBAL_$I$ConfigurationNormalizer.m9aOgYa T 00000858 _GLOBAL_OFFSET_TABLE_ U 
__objc_class_name_ConfigurationNormalizer R 00000044 
__objc_class_name_NSDictionary U __objc_class_name_NSMutableDictionary U 
__objc_class_name_NSObject U __objc_class_name_NSString U 
__objc_class_name_NXConstantString U __objc_exec_class U objc_get_class U 
objc_msg_lookup U objc_msg_lookup_super U

How (if there is a way) to get it working ?

Thanks in advance.
