C GNU make在makefile完成之前停止，没有错误

早上好， 我试图在Windows7下使用Eclipse和GNU Arm工具链交叉编译Atmel AT92SAM

我的问题是，构建过程在链接器完成后停止，尽管它还应该创建一个原始二进制文件并打印大小。 以下是eclipse创建的makefile的摘录：

# All Target
all: main.exe

# Tool invocations
main.exe: $(OBJS) $(USER_OBJS)
    @echo 'Building target: $@'
    @echo 'Invoking: Cross ARM C Linker'
    arm-none-eabi-gcc -mcpu=arm7tdmi -mthumb -O0 -fsigned-char -ffunction-sections  -g -Xlinker --gc-sections -Wl,-Map,"main.map" --entry=0x00000000 -o "main.exe" $(OBJS) $(USER_OBJS) $(LIBS)
    @echo 'Finished building target: $@'
    @echo ' '

main.bin: main.exe
    @echo 'Invoking: Cross ARM GNU Create Flash Image'
    arm-none-eabi-objcopy -O binary "main.exe"  "main.bin"
    @echo 'Finished building: $@'
    @echo ' '

main.siz: main.exe
    @echo 'Invoking: Cross ARM GNU Print Size'
    arm-none-eabi-size --format=berkeley "main.exe"
    @echo 'Finished building: $@'
    @echo ' '

但不执行最后两个命令，也不创建.bin。命令行输出为

...

如您所见，不会调用objcopy和size命令。

有什么想法吗？

您可以直接在

main.exe

配方中添加大小，因为

main.siz

不是真正的输出文件（应该是

.PHONY

）：

all:main.bin
main.exe:$（OBJS）$（用户_OBJS）
@echo“构建目标：$@”
@echo“调用：交叉臂C链接器”

您是对的。。显然eclipse选项设置不正确。您只是调用“make”还是“makeall”？如果是这样的话，它所做的正是您的“所有”目标告诉它的…
all:main.bin main.siz
您是对的。。显然，eclipse选项设置不正确。
