Results of a session wide search for EXT_PFX

Code:

main.h:15: #define EXT_PFX ACHS_C( _EXT_PFX )
main.c:135: printf( "Constructing name 'vfx%s%s'\n", app.wai.name, EXT_PFX );
main.c:138: ( &app, app.wai.File, "vfx%s%s", app.wai.name, EXT_PFX );
main.c:140: printf( "Constructing name 'vfx%s%s'\n", app.vai.name, EXT_PFX );
main.c:143: ( &app, app.vai.File, "vfx%s%s", app.vai.name, EXT_PFX );
system.mak:235: cc__opts=$(CFLAGS) $($1_opts) $($2_opts) -D _EXT_PFX="$(ext_pfx)$($1_sfx)"
Found 7 matches for "EXT_PFX".

I see no valid reason for EXT_PFX to not be the expected .linux.cc.d, any ideas what's causing it to be different?

I found the culprit, it was the compiler, it must be doing something under the hood that happens to use the same string and replaced mine along with it's own, switching the "." character for "_" gave me the correct string

Another string related problem:

Code:

_2src=$(if $(filter $1,$1),$2,$(call _2src,$(basename $1),$(basename $2)))
obj2src=$(patsubst $(OBJ_DIR)/%,$(SRC_DIR)/%,$(call _2src,$(basename $1),$1))
$(info $$(call obj2src,$(a_o)) = $(call obj2src,$(a_o)))

# variant, name
cc__opts=$(CFLAGS) $($1_opts) $($2_opts) -D _EXT_PFX="$(ext_pfx)$($1_sfx)"
# variant, name, object
cc___obj=$(CC) $(call cc__opts,$1,$2) -o $3 -c $(call obj2src,$3)
# variant, name, object
cc__obj=$(if $(filter %$(call ext,$1).o,$3),$(call cc___obj,$1,$2,$3))
# variant, name
cc__exe=$(CC) $(exe_opts) $($1_opts) $($2_opts) $(call exe_out,$1,$2) $($2_link)
cc__dll=$(CC) $(dll_opts) $($1_opts) $($2_opts) $(call dll_out,$1,$2) $($2_link)
cc__lib=ar rcs $(call lib_out,$1,$2)

# variant, name
cc_exe=$(call cc__exe,$1,$2)
cc_dll=$(call cc__dll,$1,$2)
cc_lib=$(call cc__lib,$1,$2,$3)
# name, obj
cc_obj=$(foreach i,$(variants),$(call cc__obj,$i,$1,$2))

Is given me this output:

Code:

As you can see by the last line and the test call of obj2src the object paths are not being converted back to the source file path, any ideas on how to fix this? FYI the reason I went with manual conversion back to source is to keep my targets simple further down the line like this:

Code:

$(basic_objs): $(basic_incs) $(basic_srcs)
	$(call cc_obj,basic,$@)

Never mind, managed to resolve the object to source name issue

Code:

_onesfx=$(if $(suffix $2),$(call _onesfx,$2,$(basename $2)),$1)
onesfx=$(foreach i,$1,$(call _onesfx,$i,$(basename $i)))
obj2src=$(patsubst $(OBJ_DIR)/%,$(SRC_DIR)/%,$(call onesfx,$1))
