Bitbake LibSocketCAN

Question

我正试图将libsocketcan建立在我的形象中。为了在我的主要应用程序配方中添加libsocketcan，我添加了IMAGE_INSTALL_append += " libsocketcan "。在用Eclipse调试我的应用程序时，这个功能非常好。当我试图撕毁我的申请时，有人告诉我

fatal error: libsocketcan.h: No such file or directory

我不知道我在哪里失去了我的依赖。Makefile.am

AUTOMAKE_OPTIONS = foreign subdir-objects

bin_PROGRAMS = MAIN_Application

MAIN_Application_LDADD = -lsocketcan -lpthread

AM_CPPFLAGS = \
-I$(srcdir)/include \
-I$(srcdir)/include/utilities \
-I$(srcdir)/include/comms

MAIN_Application_SOURCES = \
src/main.c \
src/scheduler.c \
src/utilities/time_conversions.c \
src/utilities/ring_buffer.c \
src/utilities/logger.c \
src/comms/can.c

我相信这是唯一能起作用的文件。还有其他人面临过这种情况吗？我还需要做些什么才能让我的烤面包找到它呢？

Answer 1

libsocketcan提供了以下软件包：

tmp/work/aarch64-poky-linux/libsocketcan/0.0.11-r0/image
└── usr
    ├── include
    │   ├── can_netlink.h
    │   └── libsocketcan.h
    ├── lib
    │   ├── libsocketcan.so -> libsocketcan.so.2.3.0
    │   ├── libsocketcan.so.2 -> libsocketcan.so.2.3.0
    │   ├── libsocketcan.so.2.3.0
    │   └── pkgconfig
    │       └── libsocketcan.pc

添加DEPENDS += "libsocketcan"将导致将所有这些文件填充到自定义层的工作目录中。

注意：您的食谱似乎没有安装您的MAIN_Application输出二进制文件。所以你的食谱看起来应该是：

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"

DEPENDS += "libsocketcan"

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
    install -m 0644 ${S}/MAIN_Application ${D}${bindir}
}

只需确保MAIN_Application是正确的二进制名称。

Answer 2

IMAGE_INSTALL_append将包添加到图像中。

这与您的应用程序的构建时依赖关系不大。

您应该添加到您的app.bb是：

取决于= "libsocketcan“

Answer 3

这是一个帮助你解决一些与你的形象食谱相关的问题的答案：

以下是一些重要的评论：

• IMAGE_INSTALL

IMAGE_INSTALL = " packagegroup-core-boot ${CORE_IMAGE_EXTRA_INSTALL}"
...
inherit core-image

永远不要在IMAGE_INSTALL之前重写core-image，因为IMAGE_INSTALL of core-image不会生效。

• Variable assignement

IMAGE_INSTALL_append += " packagegroup-core-ssh-openssh "
IMAGE_INSTALL_append += " can-utils "
IMAGE_INSTALL_append += " libsocketcan"
IMAGE_INSTALL_append += " sudo "
IMAGE_INSTALL_append += " iw wireless-tools wpa-supplicant "

不要将append与+=结合使用，只使用其中之一。

• DEPENDS ??图像食谱专门用于收集菜谱，创建图像根和最终图像类型(wic，.)你不需要DEPENDS.

• SRC_URI ??这也是一个非图像的食谱变量，它生效了吗？将内核配置片段移动到您的自定义virtual/kernel包配方.

我推荐您的形象食谱如下：

LICENSE = "MIT"
IMAGE_LINGUAS = " "

# Configure image base size
IMAGE_ROOTFS_SIZE ?= "4096"
IMAGE_ROOTFS_EXTRA_SPACE_append = "${@bb.utils.contains("DISTRO_FEATURES", "systemd", " + 2048", "", d)}"

# User preferences 
inherit core-image extrausers

# Change root password (note the capital -P)
EXTRA_USERS_PARAMS = "\
  usermod -P toor  root; \
  useradd -P michael -G sudo  michael; \
  "

# uncomment the line %sudo ALL=(ALL) ALL in /etc/sudoers
modify_sudoers() {
    sed 's/# %sudo/%sudo/' < ${IMAGE_ROOTFS}${sysconfdir}/sudoers > ${IMAGE_ROOTFS}${sysconfdir}/sudoers.tmp
    mv ${IMAGE_ROOTFS}${sysconfdir}/sudoers.tmp ${IMAGE_ROOTFS}${sysconfdir}/sudoers
}
ROOTFS_POSTPROCESS_COMMAND_append = " modify_sudoers;"

# Install necessary libraries
IMAGE_INSTALL_append = " packagegroup-core-ssh-openssh \

# Install SMG applications
IMAGE_INSTALL_append = " udevrules \
            mainapplication"

# Remove image features
IMAGE_INSTALL_remove += " packagegroup-fsl-optee-imx"
BAD_RECOMMENDATIONS = " udev-hwdb" 

#MKUBIFS_ARGS="--leb-size 126976 --min-io-size 2048 --max-leb-cnt 3600"
