Hi All,

I'm compiling vif command to powerpc executable for my project. I'm Compiling source code using powerpc ubuntu to built the vif utility with powerpc executable.

When I compile, It gives the below error,

ERROR:

make -C /lib/modules/3.12.37-rt51-QorIQ-SDK-V1.8+gf488de6/build M=/root/project modules

make: *** /lib/modules/3.12.37-rt51-QorIQ-SDK-V1.8+gf488de6/build: No such file or directory.  Stop.

When I search in forum like, how to build these directories, got some suggestions to install some packages like linux-headers-$(uname-r)

Then I try to install the package, but it is not avail

sudo apt-get install linux-headers-$(uname -r)

Reading package lists... Done

E: Couldn't find any package by regex 'linux-headers-3.12.37-rt51-QorIQ-SDK-V1.8+gf488de6'

How can I resolve this problem and make those directories available ??

Hello Vignesh,

The folder should contain Kernel source, which is generated when building Kernel, but not merged to rootfs by default.

Please refer to the following to regenerate rootfs including Kernel source.

Please add "kernel-dev" in the variable IMAGE_INSTALL in the recipe meta-fsl-networking/images/fsl-image-core.bb, and use "bitbake fsl-image-core" command to regenerate rootfs filesystem.

Kernel source will be integrated in the folder /usr/src/kernel/, create a symbolic link to make the folder /lib/modules/3.12.37-rt51-QorIQ-SDK-V1.8+gf488de6/build link to Kernel source folder.

$ln -sv /usr/src/kernel/  /lib/modules/3.12.37-rt51-QorIQ-SDK-V1.8+gf488de6/build

Have a great day,
Yiping
