Bitbake自动工具找不到makefile

Question

我正在尝试使用自动工具来构建我的项目。我正在使用Yocto和bitbake来制作Linux映像。

我阅读了一些自动教程，并遵循了我在GitHub上找到的基本指南。这与我目前的项目不太好。

我的项目结构如下：

michael@michael-VirtualBox:~/Documents/MAIN_custom/MAIN_layers/meta-MAINapplication/recipes-core/MAIN_Application$ tree
.
├── files
│   ├── MAIN_Application
│   │   ├── autogen.sh
│   │   ├── configure.ac
│   │   ├── Makefile.am
│   │   ├── project.yml
│   │   ├── src
│   │   │   ├── include
│   │   │   │   ├── main.h
│   │   │   │   ├── scheduler.h
│   │   │   │   └── utilities
│   │   │   │       └── time_conversions.h
│   │   │   └── src
│   │   │       ├── main.c
│   │   │       ├── scheduler.c
│   │   │       └── utilities
│   │   │           └── time_conversions.c
│   │   └── test
│   │       ├── test_scheduler.c
│   │       └── test_time_conversions.c
│   └── services
│       └── mainapplication.service
└── mainapplication_0.0.bb

autogen.sh：

#!/bin/sh

echo "Generating configure files... may take a while."

autoreconf --install --force && \
  echo "Preparing was successful if there was no error messages above." && \
  echo "Now type:" && \
  echo "  ./configure && make"  && \
  echo "Run './configure --help' for more information"

Makefile.am

AUTOMAKE_OPTIONS = foreign

CFLAGS = -Wall -pedantic -O2
include_HEADERS = main.h

bin_PROGRAMS = EVCC_Application
EVCC_Application_SOURCES = main.c

configure.ac

#                                               -*- Autoconf -*-
AC_PREREQ(2.60)
AC_INIT([EVCC_Application],[0.0.1],[michaelminer@smartrendmfg.com])
AM_INIT_AUTOMAKE([1.9 foreign])
AC_PROG_CC
AC_PROG_INSTALL
AC_PROG_MAKE_SET
AM_SILENT_RULES([yes])

AC_CONFIG_MACRO_DIRS([m4])
AC_CONFIG_FILES([Makefile])
AC_OUTPUT

我的bb文件也很简单：

LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"

FILESEXTRAPATHS:prepend := "${THISDIR}/files/MAIN_Application:"
FILESEXTRAPATHS:prepend := "${THISDIR}/files/MAIN_Application/src:"
FILESEXTRAPATHS:prepend := "${THISDIR}/files/services:"

SRC_URI = "\
    file://mainapplication.service \
    file://src/utilities/time_conversions.c \
    file://src/main.c \ 
    file://src/scheduler.c \    
    file://include/main.h \ 
    file://include/scheduler.h \        
    file://include/utilities/time_conversions.h \   
    file://Makefile \   
    "

inherit systemd autotools

S = "${WORKDIR}"

SYSTEMD_SERVICE_${PN} = "mainapplication.service"

do_install_append () {
    install -d ${D}${systemd_system_unitdir}
    install -m 0644 ${S}/mainapplication.service ${D}${systemd_system_unitdir}
    sed -i -e 's,@BINDIR@,${bindir},g' ${D}${systemd_system_unitdir}/mainapplication.service
}

当我在终端中运行autogen.sh时，会得到以下输出：

configure.ac:4: installing './compile'
configure.ac:2: installing './install-sh'
configure.ac:2: installing './missing'
Makefile.am: installing './depcomp'

有人能解释为什么我的比特面包构建报告说它找不到Makefile。

编辑: Bitbake找不到我的Makefile，因为它不存在。我有一个Makefile.am。当我将这个重命名为Makefile时，我会得到一个oe_runmake错误。

Answer 1

以下是我的意见：

我建议在没有指定FILESEXTRAPATHS的情况下指定完整的项目文件夹

SRC_URI = "file://MAIN_Application"
SRC_URI += "file://services/"

然后，需要将S变量指定到源文件文件夹：

S = "${WORKDIR}/MAIN_Application"

另外，请注意，autotools类将尝试在${S}中查找下列文件之一

• Makefile
• makefile
• GNUmakefile

如果存在，它将运行oe_runmake clean。

因此，请确保正确命名Makefile并向其添加clean目标。

关于autotools如何在这个链接中检查类的更详细信息

编辑

为了确保一切顺利，手动运行以下任务：

• 检查S变量值：

bitbake -e mainapplication | grep ^S=

• 在S下解压缩和检查文件

bitbake mainapplication -c unpack

您需要看到文件夹MAIN_Application及其内容。

• 尝试在autotools之前继承systemd。

EDIT2

我试图为您的Github示例链接创建一个菜谱，下面是最后的菜谱：

LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://LICENSE;md5=96af5705d6f64a88e035781ef00e98a8"
SRC_URI = "git://github.com/DynamicDevices/bbexample;protocol=https"
PV = "0.1+git${SRCPV}"
SRCREV = "b9fb7785e9e1f357f29bef63dce8f1d91adb6170"
S = "${WORKDIR}/git"
inherit autotools
EXTRA_OECONF = ""

它编译正确，因此，对于您的情况，只需设置：

LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"

SRC_URI = "\
    file://MAIN_Application \
    file://services \ 
    "

inherit autotools systemd

S = "${WORKDIR}/MAIN_Application"

SYSTEMD_SERVICE_${PN} = "mainapplication.service"

do_install_append () {
    install -d ${D}${systemd_system_unitdir}
    install -m 0644 ${WORKDIR}/services/mainapplication.service ${D}${systemd_system_unitdir}
    sed -i -e 's,@BINDIR@,${bindir},g' ${D}${systemd_system_unitdir}/mainapplication.service
}
