iMX6 linux kernel header installation

Hi All,

I decided to try the latest Linux version on my iMX6 SDB, so I downloaded the BSP and RFS, got u-boot, the kernel, and the file system running. I ran
"do-release-upgrade", waited HOURS, did a little fix-up, and now have a stable Ubuntu 12.04 / Linaro system on my SD card.

I went to build my apps, which require kernel headers, and hit a wall. The usual method to install kernel headers, "sudo apt-get install linux-headers-$(uname -r)" failed. uname -r returns 3.0.35-2666-gbdde708. I've already completed a "sudo apt-get update", so everything on my system is up-to-date.

How do I get and install the kernel headers for this release? I'm trying to avoid the whole ltib / kernel build, so if there's a way to get and install just the kernel headers, please let me know.

Thanks in advance...

What is the error log? Why do you want to native compile?

The error from my app build was that it couldn't find linux/modules.h This is several 100K lines of legacy code still built using MAKE, and it built native under the pre-release version of iMX6 and Ubuntu 11.04 / Linaro, so staying with that method seemed like the path of least resistance. I went through the ltib process for that build to get the kernel headers. I just recall it being painful and wanted to avoid it this time if possible. In Freescale's defense, it was a pre-release board with pre-release firmware / OS / software, and it still went smoother than other vendor's released product. For the iMX6 release SDB, the Linux install instructions worked, and u-boot, kernel, and file system installed as expected. If the kernel headers are available, it would save some time & effort...

Thanks
