Bitbake LibSocketCAN

Question

I am trying to build libsocketcan into my image. To add libsocketcan In my main application recipe I added IMAGE_INSTALL_append += " libsocketcan " . When debugging my application with Eclipse this works perfectly. When I attempt to bitbake my application I am told

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

I am not sure where I am missing my dependency. 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

I believe this is the only file that would make a difference. Has anyone else ever faced this? What else do I need to do to allow my bitbake to find the include?

Edit: recipe as requestes

IMAGE_LINGUAS = " "

Answer 1

IMAGE_INSTALL_append adds package to image.

It has not much to do with build-time dependencies of your application.

What you should add to you app.bb is:

DEPENDS = "libsocketcan"

Answer 2

This is an answer just to help you fix some issues related to your image recipe:

Here are some important comment:

• IMAGE_INSTALL

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

Never and never override IMAGE_INSTALL before core-image , because IMAGE_INSTALL of core-image will not take effect.

• 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 "

Do not use append with += , use one of them only.

• DEPENDS?? Image recipes are just dedicated to collect recipes and create image rootfs and final image type (wic, ...) You do not need DEPENDS .

• SRC_URI?? This is also a non-image recipe variable, did it even took effect? Move the kernel configuration fragment to your custom virtual/kernel package recipe.

I recommend your image recipe to look like:

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 \
            can-utils \
            libsocketcan \
            sudo \
            iw wireless-tools wpa-supplicant"

# 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"
#UBINIZE_ARGS="--peb-size 128KiB --min-io-size 2048 --sub-page-size 2048"
#IMAGE_FSTYPES += " ubi ubifs"

Answer 3

libsocketcan provides these packages:

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

Adding DEPENDS += "libsocketcan" will cause all those files to be populated into your custom layer's working directory.

NOTE Your recipe seems to do not install your MAIN_Application output binary file. So your recipe should look like:

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}
}

Just make sure that MAIN_Application is the right binary name.
