使用makefile編譯程序時出現問題。 make嘗試編譯名爲「startup.S」的程序集文件時只有一個問題。它看起來像使用編譯器「cc」,即使我在makefile中指定「arm-none-eabi-as」(查看變量AS)。使用「cc」而不是「arm-none-eabi-as」
這裏是我的makefile:
SHELL := /bin/bash
ROOT := $(shell pwd)
INC := $(ROOT)/inc
SRC := $(ROOT)/src
STR := $(ROOT)/str
EXE := exe
AS := arm-none-eabi-as -mcpu=arm926ej-s -c -Wall -I $(INC) -I$(SRC) -I $(STR)
GCC := arm-none-eabi-gcc -mcpu=arm926ej-s -c -Wall -I $(INC) -I$(SRC) -I $(STR)
LDSCRIPT := test.ld
LD := arm-none-eabi-ld -T $(LDSCRIPT)
HEADERS := $(notdir $(wildcard $(INC)/*.h))
SOURCES_GCC := $(notdir $(wildcard $(SRC)/*.c))
SOURCES_AS := $(notdir $(wildcard $(STR)/*.S))
OBJECTS_GCC := $(SOURCES_GCC:.c=.o)
OBJECTS_AS := $(SOURCES_AS:.S=.o)
VPATH := $(STR):$(SRC):$(INC)
all : $(EXE)
@echo konec postopka: izvrsljiv program po imenu $(EXE) se nahaja v mapi $(ROOT)
$(EXE) : $(OBJECTS_AS) $(OBJECTS_GCC)
@echo objekti so: $(OBJECTS_AS) $(OBJECTS_GCC)
@echo headerji so: $(HEADERS)
@echo linkanje objektov v izvrsljiv program...

$(GCC) -o [email protected] $<
.PHONY : clean
clean :
@echo brisanje objektov
rm *.o
@echo brisanje izvrsljivega programa
rm $(EXE)
以下是錯誤輸入COMAND時使一個終端,我得到。它清楚地表明「cc」不理解彙編語言,並且這個錯誤有點期待。
cc -c -o startup.o /home/ziga/Dropbox/diploma/86x_linux/IDE_eclipse/eclipse_projects/makefile_8/str/startup.S

如果我試圖manualy編譯它採用「臂 - 無 - EABI - 爲的Startup.s」它編譯罰款...
我的問題是,爲什麼讓使用cc而不是手臂-none-EABI,作爲?我在這裏錯過了什麼?
所有你的建議後,我設法讓一個makefile,看起來像這和它的工作:
SHELL := /bin/bash
ROOT := $(shell pwd)
INC := $(ROOT)/inc
SRC := $(ROOT)/src
STR := $(ROOT)/str
EXE := exe
AS := arm-none-eabi-as -mcpu=arm926ej-s -c -Wall -I $(INC) -I$(SRC) -I $(STR)
CC := arm-none-eabi-gcc -mcpu=arm926ej-s -c -Wall -I $(INC) -I$(SRC) -I $(STR)
LDSCRIPT := ldscript_iram_gnu.ld
LD := arm-none-eabi-ld -T $(LDSCRIPT)
HEADERS := $(notdir $(wildcard $(INC)/*.h))
SOURCES_CC := $(notdir $(wildcard $(SRC)/*.c))
SOURCES_AS := $(notdir $(wildcard $(STR)/*.S))
OBJECTS_CC := $(SOURCES_CC:.c=.o)
OBJECTS_AS := $(SOURCES_AS:.S=.o)
VPATH := $(STR):$(SRC):$(INC)
all : $(EXE)
@echo konec postopka: izvrsljiv program po imenu $(EXE) se nahaja v mapi $(ROOT)
$(EXE) : $(OBJECTS_AS) $(OBJECTS_CC)
@echo objekti so: $(OBJECTS_AS) $(OBJECTS_CC)
@echo headerji so: $(HEADERS)
@echo linkanje objektov v izvrsljiv program...
$(LD) -o [email protected] $^
%.o : %.S
@echo prevajanje ASSEMBLY izvornih datotek...
$(AS) -o [email protected] $<
%.o : %.h
%.o : %.c
@echo prevajanje C izvornih datotek...
$(CC) -o [email protected] $<
%.o : %.h
.PHONY : clean
clean :
@echo brisanje objektov
rm *.So
rm *.o
@echo brisanje izvrsljivega programa
rm $(EXE)
當我試圖在其他項目中使用相同的生成文件(項目這我的Makefile有從一開始已建成),它也具有同樣的樹結構,我得到了一些錯誤:

在我看來,我的makefile現在做的不錯,但也有它什麼都沒有做我的項目內的一些未解決的引用用我的makefile 。 我仍然需要你的構造,我的makefile可以。謝謝大家。
問候。
我會將GCC更改爲CC。 %.h應該包含先決條件中的頭文件...我已經閱讀了GNU make教程和目標系統的先決條件,這些都是這樣設置的:「target.o:prereq1.c prereq1.h」所以我按照這樣做了。我還可以包括頭文件嗎? – 71GA 2011-04-11 20:31:13
我也將%h更改爲%.h。 Regards – 71GA 2011-04-11 21:04:41
你忘了「。」以%.h(%h代替)。 您可以使用兩個規則:一個定義動作的「%.o:%.c」,然後是「%.o:%.h」,不需要任何操作作爲簡單的依賴規則 – 2011-04-12 15:36:04
