Freescale specific kernel header to compile imx-lib

My question is : can I get this header on my cross-compile machine running
Ubuntu 13.04 or am I forced to use a Freescale BSP and do a native compilation ?

Thank you for your response.

I can give you some more details.

When I only select the package "imx-lib", compilation is ok. But when I also select the package "gst-fsl-plugins", I have this issue:

Dear Thomas Petazzoni,

After I have cleaned the project, I didn't have this issue again. BEfore, I have only made the compilation in two step.

Now I have another issue (whole log attached):

I found the "ipu.h" header and I placed it in "/usr/src/linux" with no success.

What else can I do to make this header be visible ?

Thank you very much for your help. I also post my questions on the armadeus-forum mailing list but no one helps me...

Alexandre Schnegg

Armadeus is making some fairly major changes to the Buildroot packages, so I'm not sure whether the help we can provide will be 100% accurate.

<rant>

I've asked gazillions of times the Armadeus people to push their changes upstream, I'm on their IRC channel to help them to do so if they need help. But over the past 4+ years, they only contributed 25 patches to Buildroot, and have kept most of their Buildroot changes out of tree. Seems like they prefer to update their stack of patches over and over and over again.

It's seems the "imx-lib" isn't built.

The libfslvpuwrap package has a dependency on imx-lib, so it should get built before:

LIBFSLVPUWRAP_DEPENDENCIES += imx-lib

Can you restart your build from scratch (make clean; make), and log the entire build output a file:

make 2>&1 | tee build.log

And then see if imx-lib is properly built before libfslvpuwrap. If that's the case, then you should look if a vpu_lib.h file was installed somewhere. Depending on that, we'll see what's going on:
either it has been installed but libfslvpuwrap isn't looking for it at the right place, or it hasn't been installed.

Best regards,

Thomas
