sd-bus.h not found even with DEPENDS += "systemd"

sd-bus.h not found even with DEPENDS += "systemd"

Hi Community,

I'm trying to make a recipe for source files with a Makefile , files are under : https://github.com/wirepas/gateway/tree/master/sink_service

I can't add the recipe directly from the URL, so I cloned the repo and zipped only the sink_service file.

When I added the zip file with devtool it added DEPEND = "systemd" in the recipe file. But when compiling :

> 
> fatal error: systemd/sd-bus.h: No such file or directory

The Makefile just needs "make" and it worked on my native host. Here is the recipe:
LICENSE = " Unknown "
LIC_FILES_CHKSUM = " file://c-mesh-api/LICENSE;md5=b8b4f77337154d1f64ebe68dcd93fab6 "
SRC_URI = " file:///media/talel/data/multigate/multigate/meta-wirepas/recipes-wirepas/wirepas-sink-tool/files/sink_service.zip "
DEPENDS = " systemd "
do_configure () {
# Specify any needed configure commands here
:
}

do_compile () {
# You will almost certainly need to add additional arguments here
oe_runmake
}

do_install () {
# NOTE: unable to determine what to put here - there is a Makefile but no
# target named "install", so you will need to define this yourself
:
}

The only problem is in do_compile , I need to fix it and then I can manage the install part.
How can I specify the libsystemd in BUILD time , do I need EXTRA_OEMAKE ?

Thanks, Talel

HI Again,

The systemd issue is solved by installing the libsystemd in my native host, but I got another problem linking the lib with "ld" :

Hi,

A response came only to me :

So I added

EXTRA_OEMAKE += "-I ${STAGING_INCDIR}
to fix the systemd include error.

But I still get the error of :

/media/talel/data/menzu-zeus/menzu/tmp/work/aarch64-poky-linux/wirepas-sink-tool/1.0-r0/recipe-sysroot-native/usr/bin/aarch64-poky-linux/../../libexec/aarch64-poky-linux/gcc/aarch64-poky-linux/9.2.0/ld: c-mesh-api/lib/build/mesh_api_lib.a: error adding symbols: file in wrong format

I don't know what is the problem.
Help me on this please.

Thanks for your support.

Without digging into the details, it sounds very very much like the most of
your problems are caused by handcrafting a Makefile which is not cross
compile aware and probably has multiple other issues. Therefore I strongly
suggest to use a build system like autotools, cmake or meson. You can find
an introduction to a cmake-based setup here: https://youtu.be/NmPta5w6P70

can you check if sd-bus.h is in the recipe sysroot ? and if yes whats
the path to it, is your package adding the needed path to CLFLAGS via
-I ?

I am able to build this now. But seems the binary that it is generating is for native and not for target. What do we need to specify in recipe file to make sure image is generated for target.
On running file sinkService, this is what I get in output.

however, my target needs below type of file.

My service when installed in target keeps on rebooting continuously with below message:

Though it says file not present, but i can see file present in the location. Somehow target is not able to read the file. It may be because of architecture difference which I have specified above. Can anyone suggest what exactly can be the issue and what am I doing wrong here?

It seems you are mixing multilib distro with non-multilib distro. Is your
distro including multilib.conf ?
maybe check

bitbake-getvar MULTILIBS

if it is empty then you are using non-multilib variant

I do not understand when you have multilib disabled then how can a target
binary embed /lib64/ld-linux-x86_64.so.2  as desired dynamic linker. it
would be understood if multilib was enabled.

I tried to even override the linker using LDFLAGS but still linker embedded is /lib64/ld-linux-x86_64.so.2 only. Below is how i tried to explicitly set lib/ld-linux-x86-64.so.2

EXTRA_OEMAKE += "LD_LIBRARY_PATH=${COMPONENTS_DIR}/core2-64/glibc/lib/ld-linux-x86-64.so.2:${LD_LIBRARY_PATH}"
LDFLAGS += " -dynamic-linker ${COMPONENTS_DIR}/core2-64/glibc/lib/ld-linux-x86-64.so.2"

What package are you building and can you share the recipe? It sounds like the makefiles are broken.

Sorry, will not be able to share entire recipe file but make file is open source, I am just trying to call it from recipe.
make file path : https://github.com/wirepas/gateway/tree/master/sink_service

Ideally it should not be broken. Issue seems to be more from point that somehow make file is not generating image for target, rather it is doing for host only. Seems it is failing to cross compile.

The makefiles are hand written and therefore it’s wise to assume that they’re broken by design: writing a proper makefile is harder than people think.

Check the compile log, it should be calling the cross compiler and passing —sysroot, if it’s just running “gcc” then your recipe needs to force the makefiles to do the right thing.
