Building Yocto image, DirectFB2 unable to find Fluxcomp-native both my own recipes

Question

I am trying to build DirectFB2 for my yocto image to be deployed on a Raspberry Pi 0 W. In order to do so, I requre Fluxcomp. From the github page for fluxcomp: "flux is an interface description language used by DirectFB". This is a tool used when building DirectFB2, however it is not required within the image which I am building for deployment (building for native not nativesdk). This is an issue I have been trying to work my way through for a few weeks now and suspect that it's more or less due to my inexperience with yocto.

At this stage, it appears that I am actually able to include the fluxcomp binary in /usr/bin/ however, it is named fluxcomp-native rather than fluxcomp. I can find nowhere that it is being named this during the build process.

Take note that before building a recipe, I perform a cleanall on it (so before building fluxcomp, I run bitbake -c cleanall fluxcomp, etc.

When I build fluxcomp with the command bitbake fluxcomp, I find the binary I would expect at build/tmp/work/arm1176jzfshf-vfp-poky-linux-gnueabi/fluxcomp/1.0+gitAUTOINC+10ad2ebc78-r0/image/usr/bin/, with only the fluxcomp binary in that directory. However, when I try to build fluxcomp-native like so; bitbake fluxcomp-native, I receive the following error;

| install: cannot stat 'build/tmp/work/x86_64-linux/fluxcomp-native/1.0+gitAUTOINC+10ad2ebc78-r0/build/fluxcomp-native': No such file or directory

When inspecting further into this directory, I find that it contains the binary named fluxcomp but not fluxcomp-native. I don't know how to tell bitbake that I want it to check for the binary at the name fluxcomp as that is the desired name for this binary.

If I move forward anyway and run bitbake build-sysroots, then under build/tmp/sysroots/x86_64/usr/bin, it is currently not placing fluxcomp-native. Previously it was, I don't know what I have done to stop this which seems like a step backwards for me. However ideally, I want it to be named fluxcomp.

Moving forward, I need to be able to run bitbake directfb2 and for it to build - currently, it is giving the same error as when I run bitbake fluxcomp-native.

Here is my fluxcomp.bb recipe;

S = "${WORKDIR}/git"
B = "${S}/src/build"

inherit autotools pkgconfig

do_configure() {
    # Generate the configure script using autotools
    if [ -f ${S}/configure.in ]; then
        mv ${S}/configure.in ${S}/configure.ac
    fi

    MYBUIDDIR=$(pwd)
    cd ${S}

    autoreconf -i -f -I ${S}/configure.ac
    # Run configure with the necessary options
    ${S}/configure --host=${TARGET_SYS} --prefix=${S} --exec-prefix=${exec_prefix} --bindir=${STAGING_BINDIR_NATIVE} --libdir=${libdir}
    cd ${MYBUILDDIR}

do_compile() {

    cd ${S}
    make -j 4 
    mkdir -p ${B}

    cp ${S}/src/fluxcomp ${B}/fluxcomp
    cp ${S}/src/fluxcomp.o ${B}/fluxcomp.o

    cd ${MYBUILDDIR}
}

do_install() {
    echo "DO_INSTALL FLUXCOMP TO ${D}${bindir}"
    install -d ${D}${bindir}
    install -m 0755 ${B}/${PN} ${D}${bindir}/
}

# Specify where the files will be installed
FILES_${PN} += "${bindir}/fluxcomp"

And my directfb2.bb recipe:

FILES_${PN}-dev += "${includedir}/directfb"

S = "${WORKDIR}/git"

inherit meson pkgconfig

do_show_fluxcomp_path() {
    echo "Fluxcomp dir: ${STAGING_BINDIR_NATIVE}"
}
addtask show_fluxcomp_path before do_configure

# Configure options for meson
EXTRA_OEMESON = '\

do_configure() {

    meson ${EXTRA_OEMESON} ${S} ${B}
}

do_compile() {
    ninja -C ${B}
}

do_install() {
    ninja -C ${B} install
    rm -rf ${D}${libdir}/libdirectfb*
}

Any thoughts would be appreciated.

Answer 1

Ok, so I only had to make 2 changes to my fluxcomp recipe in order to get this building correctly. The changes I made related to the last couple of lines in the fluxcomp.bb file, by changing the second install line, removing ${PN} and replcing it with fluxcomp (I had already tried this but found some issue, I don't remember what it was) and also changing on the last line ${bindir} to `${STAGING_BINDIR_NATIVE}:

    echo "DO_INSTALL FLUXCOMP TO ${D}${bindir}"
    install -d ${D}${bindir}
    install -m 0755 ${B}/fluxcomp ${D}${bindir}/
}

FILES_${PN} += "${STAGING_BINDIR_NATIVE}/fluxcomp"

I am now able to build fluxcomp and configure directfb2 however having issues with cross compilation, but that's a separate issue.
