VPATH and vpath are out since we can't be sure that the search order and matching by file name only will produce the correct match. a file in a different dir with the same name could cause trouble.

re:
$(TARGETS): %.c: $(filter %.ec,$(SOURCES))
instead of just
$(TARGETS): %.c: %.ec

these are out since the built-in function calls (i.e.: filter) are performed before any of the % patterns are expanded.

here is what works:

all the rules in the following section can be replaced by a single static pattern rule:

# C OBJECT RULES
$(OBJS_OF_C_FILE_FOR_EACH_EC_FILE): $(OBJ)%$(O): $(OBJ)%.c
    $(CC) $(CFLAGS) $(PRJ_CFLAGS) $(FVISIBILITY) -c $< -o $@

in the case of per-file arguments, something like:

$(OBJS_OF_C_FILE_FOR_EACH_EC_FILE): $(OBJ)%$(O): $(OBJ)%.c
    $(CC) $(CFLAGS) $(PRJ_CFLAGS) $(FVISIBILITY) -c $< -o $@

$(OBJS_OF_C_FILE_FOR_EACH_EC_FILE_ARGS_1): $(OBJ)%$(O): $(OBJ)%.c
    $(CC) $(CFLAGS) $(PRJ_CFLAGS_ARGS_1) $(FVISIBILITY) -c $< -o $@


that was the simple stuff

now for source files that are in dirs for the rules of the following sections:

# SYMBOL RULES

$(SYMBOLS): $(OBJ)%.sym: $(srcdir)%.ec
    $(ECP) $(CFLAGS) $(CECFLAGS) $(ECFLAGS) $(PRJ_CFLAGS) -c $< -o $@

$(SYMBOLS_FROM_DIR_A): $(OBJ)%.sym: $(srcdir)../dir/a/%.ec
    $(ECP) $(CFLAGS) $(CECFLAGS) $(ECFLAGS) $(PRJ_CFLAGS) -c $< -o $@

# C OBJECT RULES

$(TARGETS): $(OBJ)%.c: $(srcdir)%.ec
    $(ECC) $(CFLAGS) $(CECFLAGS) $(ECFLAGS) $(PRJ_CFLAGS) $(FVISIBILITY) -c $< -o $@ -symbols $(OBJ)

$(TARGETS_FROM_DIR_A_SRC): $(OBJ)%.c: $(srcdir)../dir/a/%.ec
    $(ECC) $(CFLAGS) $(CECFLAGS) $(ECFLAGS) $(PRJ_CFLAGS) $(FVISIBILITY) -c $< -o $@ -symbols $(OBJ)

and those 4 static pattern rules would need to be multiplied by any applying per-file flags

note that I have omitted some calls around the $< and $@ automatic variables for simplicity

expected issues with these static pattern rules:

I suspect that if $(targets) contains files with spaces in them, make will *not* be able to properly handle these files instead treating the spaces as list separator.

and I don't think that quoting the files in these file lists will help but it's worth a try... quoting, escaping or both, etc...

the messy stuff, which can mostly be disregarded, that was in the "additional information" field:


// .ec files that use specific flags should be grouped by flags signature and be handled as follow
// each unique flags signature should be given it's own set of flags variables as well as it own file list
// CFLAGS-C1, OFLAGS-C1, ECFLAGS-C1
// ECSOURCES-C1
// proper static rules should be generated for each flags signature like this:
f.Printf("# STATIC PATTERN RULES\n");
f.Printf("\n");
f.Printf("$(SYMBOLS-C1): %%$(S): %%$(P)\n");
f.Printf(" $(ECP) $(CECFLAGS-C1) $(ECFLAGS-C1) $(CFLAGS-C1) -c $< -o $@\n");
f.Printf("\n");
f.Printf("$(COBJECTS-C1): %%$(T): %%$(P) %%$(S) | $(SYMBOLS)\n");
f.Printf(" $(ECC) $(CECFLAGS-C1) $(ECFLAGS-C1) $(CFLAGS-C1) $(FVISIBILITY) -c $< -o $@ -symbols $(OBJ)\n");
f.Printf("\n");
f.Printf("$(OBJECTS-C1): %%$(O): %%$(T)\n");
f.Printf(" $(CC) $(CFLAGS-C1) $(FVISIBILITY-C1) -c $< -o $@\n");
f.Printf("\n");
// custom flags signature file lists should be combined in a master list
// ECSOURCES-ALL-CUSTOM = $(ECSOURCES-C1) [$(ECSOURCES-C2) [...]]
// lists of non-custom (common) flags signature files should be generated
// ECSOURCES-COMMON = $(call shwspace,$(filter-out $(_ECSOURCES-ALL-CUSTOM),$(_ECSOURCES)))
// the following lists and possibly more should be generated as needed
// SYMBOLS-COMMON, COBJECTS-COMMON and OBJECTS-COMMON
// SYMBOLS-C1, COBJECTS-C1 and OBJECTS-C1
// need to find list names and write static pattern rules for custom flags
// signature files of other extension than .ec

// when no custom flags files
f.Printf("# STATIC PATTERN RULES\n");
f.Printf("\n");
f.Printf("$(SYMBOLS): %%$(S): %%$(P)\n");
f.Printf(" $(ECP) $(CECFLAGS) $(ECFLAGS) $(CFLAGS) -c $< -o $@\n");
f.Printf("\n");
f.Printf("$(COBJECTS): %%$(T): %%$(P) %%$(S) | $(SYMBOLS)\n");
f.Printf(" $(ECC) $(CECFLAGS) $(ECFLAGS) $(CFLAGS) $(FVISIBILITY) -c $< -o $@ -symbols $(OBJ)\n");
f.Printf("\n");
f.Printf("$(OBJECTS): %%$(O): %%$(T)\n");
f.Printf(" $(CC) $(CFLAGS) $(FVISIBILITY) -c $< -o $@\n");
f.Printf("\n");

// when custom flags files are present
f.Printf("# STATIC PATTERN RULES\n");
f.Printf("\n");
f.Printf("$(SYMBOLS-COMMON): %%$(S): %%$(P)\n");
f.Printf(" $(ECP) $(CECFLAGS) $(ECFLAGS) $(CFLAGS) -c $< -o $@\n");
f.Printf("\n");
f.Printf("$(COBJECTS-COMMON): %%$(T): %%$(P) %%$(S) | $(SYMBOLS-COMMON)\n");
f.Printf(" $(ECC) $(CECFLAGS) $(ECFLAGS) $(CFLAGS) $(FVISIBILITY) -c $< -o $@ -symbols $(OBJ)\n");
f.Printf("\n");
f.Printf("$(OBJECTS-COMMON): %%$(O): %%$(T)\n");
f.Printf(" $(CC) $(CFLAGS) $(FVISIBILITY) -c $< -o $@\n");
f.Printf("\n");




// check what this is
f.Printf("# IMPLICIT OBJECT RULE\n\n");
f.Printf("$(OBJ)%%$(O) : $(OBJ)%%.c\n");
f.Printf("\t$(CC) $(CFLAGS) $(FVISIBILITY) -c $< -o $@\n\n");


// nice troubleshoot target, improve upon
f.Printf("\n");
f.Printf("troubleshoot:\n");
f.Printf(" @$(call echo,ECSOURCES = $(ECSOURCES))\n");
if(compiler.separatePreprocessing)
   f.Printf(" @$(call echo,PREPECS = $(PREPECS))\n");
f.Printf(" @$(call echo,SYMBOLS = $(SYMBOLS))\n");
f.Printf(" @$(call echo,IMPORTS = $(IMPORTS))\n");
f.Printf(" @$(call echo,COBJECTS = $(COBJECTS))\n");


// if subdirs are used to store source files, the rule that maps source files
// to object files must be specified for each file. no static pattern rule is
// able to do this perfectly. see attempt(s) below.



//
// misc makefile stuff:
// #VPATH = ../extras/gui/controls ../extras ../extras/gui src/dialogs src/project src/designer src/debugger src/panels src/documents src
//
// # attempt at writing a static pattern rule for PREPS
// # filter could be problematic with files that end with same chars like: MyFile.ec and File.ec
// #$(PREPS): %$(P): $(filter %%.ec,$(SOURCES))
// #$(PREPS): %$(P): $(notdir %.ec)
// #$(PREPS): %$(P): %.ec
// # $(CPP) -x c -E $< -o $@
