Petalinux中多个C文件的执行错误

Question

我是新的2016.4。我在目标Zybo-Z7板上成功地安装了linux操作系统。我还构建了一个helloworld应用程序，到目前为止还不错。目前，我想测试我的应用程序，它的名称是test.c，有额外的一个头和C文件(new.c，new.h)。文件test.c、new.c、new.h位于路径中：

/$Petalinux-project-dir/project-spec/meta-user/recipes-apps/test/test

C有代码：

#include <stdio.h>
#include "new.h"

int main(int argc, char **argv)
{
        printf("Hello World!\n");

        return 0;
} 

new.c有以下代码：

#include "new.h"

void fun(void)
{
    printf("my function!\n");

}

new.h有以下单行代码：

#include <stdio.h>

Makefile有以下内容：

APP = test

# Add any other object files to this list below
APP_OBJS = test.o
APP_OBJS += new.o


all: build

build: $(APP)

$(APP): $(APP_OBJS)
    $(CC) $(LDFLAGS) -o $@ $(APP_OBJS) $(LDLIBS)

clean:
    $(RM) $(APP) $(OBJS)

最后，bitbake文件test.bb：

#
# This file is the test recipe.
#

SUMMARY = "Simple test application"
SECTION = "PETALINUX/apps"
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"

SRC_URI = "file://test.c \
           file://new.c \
           file://new.h \
           file://Makefile \
          "

S = "${WORKDIR}"

do_compile() {
         oe_runmake
}

do_install() {
         install -d ${D}${bindir}
         install -m 0755 test ${D}${bindir}
         install -m 0755 new ${D}${bindir}
}

然后，我尝试通过输入命令构建应用程序：

petalinux-build -c test -x build 

但是，我在log.do_configure中得到了以下错误消息：

DEBUG: Executing python function sysroot_cleansstate
DEBUG: Python function sysroot_cleansstate finished
DEBUG: Executing shell function do_configure
NOTE: make clean
make: *** No rule to make target 'clean'.  Stop.

petalinux-build -c test -x build

我在控制台中有以下内容：

我试过：https://forums.xilinx.com/t5/Embedded-Linux/How-to-build-when-multiple-source-files-in-rootfs-of-petalinux/td-p/780949和https://www.xilinx.com/support/answers/67189.html，还有这个类似的问题，How to build when multiple source files in rootfs in embedded linux?，但是它不起作用！

你能帮帮我吗？

生成文件中没有clean目标。尝试：

APP := test

APP_OBJS := test.o new.o

.PHONY: all build clean

all: build

build: $(APP)

$(APP): $(APP_OBJS)
    $(CC) $(LDFLAGS) -o $@ $(APP_OBJS) $(LDLIBS)

clean:
    $(RM) $(APP) $(OBJS)
