How to write custom recipe to install AWS C SDK from github #dunfell #linux #yocto

Hi,

I'm trying to write a recipe to install AWS SDK into the build(https://github.com/aws/aws-iot-device-sdk-embedded-C), but I complete don't know how to do it. Based on online example https://github.com/joaocfernandes/Learn-Yocto/blob/master/develop/Recipe-CMake.md I have written my recipe file and download the sdk into files folder of my recipe. When I run build do_configure got failed.

SUMMARY = "AWS IoT SDK EMBEDDED C"
SECTION = "examples"
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"

SRC_URI = "file://CMakeLists.txt"

S = "${WORKDIR}"

inherit cmake

EXTRA_OECMAKE = ""

I know it is wrong, but kindly please someone help to write it correctly, thank you.

Thanks & Regards,
VR

I suggest looking at meta-aws (https://github.com/aws/meta-aws) to see
if that has a recipe already, and if it doesn't use one of the recipes
there as a starting point.

Where is the sdk? You need to add it into your SRC_URI (you can also
just pass a URL to a git repo or tarball download link).

Hi Quentin Schulz,

Thanks for the reply. I had downloaded the SDK into "files" folder of my recipe and given CMakeLists.txt as SRCURI. Is it correct to do like this?

Here is the Error: (It's a long error)

You need to put the SDK filename into SRC_URI as well otherwise Yocto
does not fetch it from the files directory.

Also, Ross had a good suggestion too, please check that the recipe or a
similar one does not exist already in meta-aws (or other layers).

Hi Quentin Schulz & Ross,

Thanks for the information. Based on meta-aws I had written the recipe and do_compile has completed. Now I want to install demos in to the build which are located at tmp/work/aarch64-poky-linux/aws/1.0-r0/git/demos/mqtt/mqtt_demo_mutual_auth, so how do I write do_install? ( https://github.com/aws/aws-iot-device-sdk-embedded-C/tree/main/demos/mqtt/mqtt_demo_mutual_auth )

do_install() {
install -d ${D}${bindir}
install -m 0755 mqtt_demo_mutual_auth ${D}${bindir}
}

Does above code works?

Thanks & Regards,
VR.

Hi,

do_install failed with an error "ninja: error: unknown target 'install'". Kindly please help me to fix the above issue.
