bitbake custom-image | do_fetch: Fetcher Failure

357 views Asked by At

I am trying to build a Linux image using Yocto, and I want to run a simple Qt6 application with it on a Raspberry Pi4.

I have an issue after starting to build ($ bitbake custom-image). It says, that my .cpp and .pro file, which I have drawn from my Qt Creator project, cannot be fetched, see error log below.

WARNING: qtexample-0.1-r0 do_fetch: Failed to fetch URL file://qtexample.pro, attempting MIRRORS if available
ERROR: qtexample-0.1-r0 do_fetch: Fetcher failure: Unable to find file file://qtexample.pro anywhere. The paths that were searched were:

I have included the meta-qt6 layer, and the openembedded layer. All my layers are in the correct branch for yoctio version (kirkstone) and I use Qt6.5 LTS branch in meta-qt6.

My custom-image.bb file is inside /meta-custom/receipe-core/images and looks as follows:

SUMMARY = "Custom Linux image."

IMAGE_INSTALL = "packagegroup-core-boot ${CORE_IMAGE_EXTRA_INSTALL}"

IMAGE_LINGUAS = " "

LICENSE = "MIT"

inherit core-image

# Set rootfs to 200 MiB by default
IMAGE_OVERHEAD_FACTOR ?= "1.0"
IMAGE_ROOTFS_SIZE ?= "204800"
IMAGE_ROOTFS_EXTRA_SPACE:append = "${@bb.utils.contains("DISTRO_FEATURES", "systemd", " + 4096", "", d)}"

# Include Qt example application
IMAGE_INSTALL += "qtexample"

My qtexample_0.1.bb recipe, to build the application in the layer, is located at /meta-custom/recipe-apps/qtexample/qtexample_0.1.bb and looks as follows:

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

SRC_URI = "file://qtexample.pro \
           file://qtexample.cpp"

DEPENDS += "qtbase"
RDEPENDS_${PN} += "qtwayland"

S = "${WORKDIR}"

inherit qt6-qmake

Inside /qtexample, there is /qtexample/file, where my .cpp and .pro files from the Qt creator app live.

As you can see in the error message, Bitbake tried a list of paths to find your file file://qtexample.pro, one of them is:

/home/bkeohane/Projekte/yocto/meta-custom/recipes-apps/qtexample/files/

So, you need files and not file, you should have the following structure in your meta-custom:

meta-custom/
  `-- recipes-apps/
      `-- qtexample/
          |-- qtexample_0.1.bb
          `-- files/
              |-- qtexample.pro
              `-- qtexample.cpp

NOTE 1: Your path is incorrect:

.. is located at /meta-custom/recipe-apps/qtexample/qtexample_0.1.bb ..
                                   ^
                                   | HERE it should be recipes-apps

NOTE 2: Generally when having local files for your recipe, you can put them in one of the following:

  • files: In your case: meta-custom/recipes-apps/qtexample/files
  • ${PN}: In your case: meta-custom/recipes-apps/qtexample/qtexample
  • ${PN}-${PV}: In your case: meta-custom/recipes-apps/qtexample/qtexample-0.1

As you can see that bitbake tried those 3 paths:

/home/bkeohane/Projekte/yocto/meta-custom/recipes-apps/qtexample/qtexample-0.1/
/home/bkeohane/Projekte/yocto/meta-custom/recipes-apps/qtexample/qtexample/
/home/bkeohane/Projekte/yocto/meta-custom/recipes-apps/qtexample/files/

Other custom folder names should be added to FILESEXTRAPATHS, example (folder: custom-folder), with:

FILESEXTRAPATHS:prepend := "${THISDIR}/custom-folder:"
