Listen auf eval in einem Makefile

Question

Ich brauche einige Makros auf Ziele ausgewertet werden, aber ich kann OBJECT_FILE nicht durch $^aparently ausgewertet werden. dies ist meine Make-Datei:

#___________________________________build tools_________________________________ 

MKDIR := mkdir 
RM  := rm 
CP  := cp 
CD  := cd 
COMPILER := gfortran 

GENERAL_FLAGS  := -fno-automatic -static -I/usr/include -fimplicit-none 
TESTING_DEBUG_FLAGS := -Og -g -fbounds-check -fbacktrace -pedantic -Wextra \ 
        -Wall ${GENERAL_FLAGS} 
RELEASE_FLAGS  := ${GENERAL_FLAGS} -Ofast 

#______________________________macros de diretórios_____________________________ 

SRC_DIR  := src 
BUILD_DIR := build 
RELEASE_DIR := release 
DEBUG_DIR := debug 
TEST_DIR := test 
DIST_DIR := dist 

PROGRAM := ${DIST_DIR}/SimulArroz 

#______________________________regras de compilação_____________________________ 

tests: | TEST_PATHS ${PROGRAM} 

TEST_PATHS: 
    $(eval FLAGS  = ${TESTING_DEBUG_FLAGS}) 
    $(eval OBJECT_DIR = ${BUILD_DIR}/${TEST_DIR}) 
    $(eval OBJECT_FILES = ${OBJECT_DIR}/Data.o ${OBJECT_DIR}/Model.o \ 
       ${OBJECT_DIR}/Control.o ${OBJECT_DIR}/Farmings.o \ 
       ${OBJECT_DIR}/Test_data.o ${OBJECT_DIR}/Test_main.o \ 
       ${OBJECT_DIR}/Test_subroutines.o) 
    ${MKDIR} -p ${DIST_DIR} 
    ${MKDIR} -p ${OBJECT_DIR} 

clean : 
    ${RM} -fr ${BUILD_DIR} 
    ${RM} -fr ${DIST_DIR} 
    ${RM} -f seed.mod 

run : 
    ${CD} ${DIST_DIR} ; ./${PROGRAM} 

${PROGRAM}: ${OBJECT_FILES} 
    ${COMPILER} ${FLAGS} -o $@ $^ 

${OBJECT_DIR}/%.o: ${SRC_DIR}/%.f90 
    ${MKDIR} -p ${OBJECT_DIR} 
    ${COMPILER} ${FLAGS} -c -o $@ $< 

Das Ergebnis, das ich bekommen ist:

gfortran -Og -g -fbounds-check -fbacktrace -pedantic -Wextra -Wall -fno-automatic -static -I/usr/include -fimplicit-none -o dist/SimulArroz 
gfortran: fatal error: no input files; unwilling to write output files 
compilation terminated. 
makefile:90: recipe for target 'dist/SimulArroz' failed 
make: *** [dist/SimulArroz] Error 1 

Update:

Ich versuchte secondary expansion wie in Kommentaren darauf aber immer noch, schließlich auf meinem Fall ist es Geben Sie das gleiche Ergebnis, hier sind die Änderungen, die ich versucht habe:

tests: FLAGS  := ${TESTING_DEBUG_FLAGS} 
tests: OBJECT_DIR := ${BUILD_DIR}/${TEST_DIR} 
tests: OBJECT_FILES := ${TEST_OBJ_DIR}/Data.o ${TEST_OBJ_DIR}/Model.o \ 
       ${TEST_OBJ_DIR}/Control.o ${TEST_OBJ_DIR}/Farmings.o \ 
       ${TEST_OBJ_DIR}/Test_data.o ${TEST_OBJ_DIR}/Test_main.o \ 
       ${TEST_OBJ_DIR}/Test_subroutines.o 

.SECONDEXPANSION: 
tests: $$(PROGRAM) 

${PROGRAM}: ${OBJECT_FILES} 
    ${MKDIR} -p ${DIST_DIR} 
    ${COMPILER} ${FLAGS} -o $@ $^ 

${OBJECT_DIR}/%.o: ${SRC_DIR}/%.f90 
    ${MKDIR} -p ${OBJECT_DIR} 
    ${COMPILER} ${FLAGS} -c -o $@ $< 

Answer 1

Ok, ich habe es weiter untersucht, und wie in Fragekommentare gezeigt, ist es möglich, mein Problem mit second expansion zu lösen, ich habe es unter Verwendung text function auch gemacht. Da niemand eine Antwort kam ich stelle es hier:

#___________________________________build tools_________________________________ 

MKDIR := mkdir -p 
RM  := rm 
CP  := cp 
CD  := cd 
COMPILER := gfortran 

# flags do compilador 

GENERAL_FLAGS  := -fno-automatic -static -I/usr/include -fimplicit-none 
TESTING_DEBUG_FLAGS := -Og -g -fbounds-check -fbacktrace -pedantic -Wextra \ 
         -Wall ${GENERAL_FLAGS} 
RELEASE_FLAGS  := ${GENERAL_FLAGS} -Ofast 

#______________________________macros de diretórios_____________________________ 

SRC_DIR  := src 
BUILD_DIR := build 
RELEASE_DIR := release 
DEBUG_DIR := debug 
TEST_DIR := test 
DIST_DIR := dist 

test_FILES := Data.o Model.o Control.o Farmings.o Test_Data.o Test_Main.o \ 
       Test_Subroutines.o 

#______________________________regras de compilação_____________________________ 

.PHONY: test clean run 

test: FLAGS  := ${TESTING_DEBUG_FLAGS} -o 
test: OBJ_DIR  := ${BUILD_DIR}/${TEST_DIR} 
test: PROGRAM_DIR := ${DIST_DIR}/${TEST_DIR} 
test: PROGRAM  := ${PROGRAM_DIR}/SimulArroz 

.SECONDEXPANSION: 
test: $${$$@_FILES} 
     ${MKDIR} ${PROGRAM_DIR} 
     ${COMPILER} ${FLAGS} ${PROGRAM} $($@_FILES:%o=${OBJ_DIR}/%o) 

%.o: ${SRC_DIR}/%.f90 
    ${MKDIR} ${OBJ_DIR} 
    ${COMPILER} -c ${FLAGS} ${OBJ_DIR}/$@ $< 

clean : 
    ${RM} -fr ${BUILD_DIR} 
    ${RM} -fr ${DIST_DIR} 
    ${RM} -f seed.mod 

run : 
    ${CD} ${DIST_DIR} ; ./${PROGRAM} 

aber ... ich kann immer noch nicht, warum Figur kann ich nicht nur ein Ziel, wie erhalten:

${OBJ_DIR}/%.o: ${SRC_DIR}/%.f90 
    ${MKDIR} ${OBJ_DIR} 
    ${COMPILER} -c ${FLAGS} $@ $< 

als ${OBJ_DIR} wurde nicht erweitert, wenn es im Ziel verwendet wurde. Wenn jemand erklären kann, was in diesem Fall passiert, würde ich mich sehr freuen.

Ich möchte den Vorschlag danken, den ich in den Kommentaren auch erhielt.
