i.MX 8M Plus Compiling the Kernel error

ezohc21 — Tue, 08 Apr 2025 14:04:13 GMT

I am currently encountering an issue while attempting to compile the kernel. When I run the following command:

$ make -j $(nproc)

I receive the following error message:

Hello,

Try to erase everything about yocto and try this UG10164 i.MX Yocto Project User's Guide Rev. LF6.6.52_2.2.0 and this is the kernel version I have cloned using the step given in this doc -
"repo init -u https://github.com/nxp-imx/imx-manifest
-b imx-linux-scarthgap -m imx-6.6.52-2.2.0.xml"

To build the Image and populate SDK, the steps followed are listed below:

Image:
$ DISTRO=fsl-imx-xwayland MACHINE=imx93-11x11-lpddr4x-evk source imx-setup-release.sh -b
build-xwayland
$ bitbake imx-image-full

Populate SDK: (Used the same environment with which I build the above Image)
$ DISTRO=fsl-imx-xwayland MACHINE=imx93-11x11-lpddr4x-evk bitbake imx-image-full -c populate_sdk

Then used the .sh file generated and executed it and sourced it in another environment and followed the below steps for Linux Kernel Standalone build:
$ git clone https://github.com/nxp-imx/linux-imx -b lf-6.6.y
$ cd linux-imx
$ make imx_v8_defconfig
$ make

I have compiled the 6.6.52 kernel without errors.

regards

Thank you for your reply. Also when I try this command, I have compiled without errors.

$HOSTLDFLAGS="-ldl -lpthread" make -j$(nproc)

best regards
