microros librart not include properly

[USER_RG]

Hi everyone,
I'll start by saying I'm just starting to use STM32cubeIDE. I'm having trouble configuring the microros configuration  in my project involving an STM32F767zi board.
Specifically, I managed to include everything I needed, and now when I compile, the result is as follows:

make -j8 all

docker pull microros/micro_ros_static_library_builder:jazzy && docker run --rm -v /home/guglielmo/PROJECTS/provamicroros:/project --env MICROROS_LIBRARY_FOLDER=micro_ros_stm32cubemx_utils/microros_static_library_ide microros/micro_ros_static_library_builder:jazzy

Can you help me or tell me if there's already a post like this I can consult?

So that's the linker saying it can't find microros - presumably that's a pre-built library?

Does that library actually exist in your project?

If it does, is it in a place where the Linker is searching?

You specify the Linker search path here:

[Pavel A.]

So what is the path part of the libmicroros.a ?

-L/home/guglielmo/PROJECTS/provamicroros/micro_ros_stm32cubemx_utils/microros_static_library_ide/libmicroros/include

The "include" at the end looks suspicious.

It should be a pre-built library. Could you help me verify this?

My linker search path is made as in the follow figure

libraries: microros

libraries search path: /home/guglielmo/PROJECTS/provamicroros/micro_ros_stm32cubemx_utils/microros_static_library/libmicroros

note: My workspare is:

/home/guglielmo/PROJECTS/provamicroros

But the error indicates that it does not include something at the following link:

home/guglielmo/st/stm32cubeide_1.19.0/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.12.3.rel1.linux64_1.1.0.202410170702/tools/bin/../lib/gcc/arm-none-eabi/12.3.1/../../../../arm-none-eabi/bin/ld

[USER_RG]

the path of libmicroros.a is 

/home/guglielmo/PROJECTS/provamicroros/micro_ros_stm32cubemx_utils/microros_static_library/libmicroros

but not incluede  microrso....

[USER_RG · Accepted solution]

I fixed the library link search path as
/home/guglielmo/PROJECTS/provamicroros/micro_ros_stm32cubemx_utils/microros_static_library/libmicroros

and now build properly......

THANKS
