[Solved] Problem tring to run gtk hello world (developper package) with bitbake (distribution package) : don't find how to properly source gtk.

[BJola.1]

Hello,

I'm trying to embed an app in the st-linux distribution. I mean that the goal is to have it compiled with bitbake and integrated in a custom st-image-weston.

I tried to use the gtk hello world example of Developper section (that run without problems) but with distribution package. ( https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-DK2/Develop_on_Arm%C2%AE_Cortex%C2%AE-A7/Create_a_simple_hello-world_application )

So I made a bitbake recipe but when I run it I get the error "error: gtk/gtk.h: No such file or directory".

But bitbake layers include gtk+3, when I run bitbake gtk+3 it is successful.

I tried adding gtk3 to compiling flags, DEPENDS, RDEPENDS, do_configure[depends] but nothing worked. The only thing that worked is sourcing the developper package sdk environnement setup, but it's weird. I'm a little of a beginner with bitbake and I didn't found how to make that developper package app work with the distribution package.

Here is my .bb file :

# Recipe created by recipetool
# This is the basis of a recipe and may need further editing in order to be fully functional.
# (Feel free to remove these comments when editing.)

do_configure () {
	# Specify any needed configure commands here
	:
}
 
do_compile () {
	# You will almost certainly need to add additional arguments here
	#. /mnt/sda3/STM32MP15-Ecosystem-v3.0.0/Developer-Package/openstlinux-5.10-dunfell-mp1-21-03-31/SDK/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi
    cd ${S}
	#oe_runmake
    ${CC} ${CFLAGS} ${LDFLAGS} gtk_hello_world.c -o gtk_hello_world
}
 
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
	:
	#oe_runmake install
}

The source code is included with .bbappend file. I succesfully implemented a led blinking program and the following link into st-image-weston with bitbake but can't figure how to do in that case.

Any help would be appreciated. And thank you for reading that post.

Hi @BJola.1​ 

The message error you get means the gtk+ environment is not yet available in your bitbake environment when building your recipe.

I think you could add the line

DEPENDS = "gtk+3"

in your bitbake recipe as it depends on gtk+3 at build time.

Best regards,

Thank you for answering.

I tried that, but it doesn't seem to be taken in account, the error message is the same.

$ bitbake gtktest

Exactly same message with and without. I tried with "=" and "+=" to be sure. I don't understand why bitbake dont include it. I also tried RDEPENDS and do_configure (but not sure how to use do_configure[depends]).

Best regards.

Hello @BJola.1​ 

Thank you for your feedback.

Could you try to update your recipe by adding this line:

inherit pkgconfig

and updating your compilation line by adding a call to pkg-config:

${CC} ${CFLAGS} ${LDFLAGS} gtk_hello_world.c -o gtk_hello_world `pkg-config --cflags --libs gtk+-3.0`

This call to pkg-config should instruct the compiler where to find gtk sources when building your binary.

Best regards,

--JM

[BJola.1]

Tried with success, thank you !

I tried something with pkg-config but it didn't worked as I didn't think to inherit.

Thank you for your help.

Best regards.
