How do I add the fftw package to my rootfs build using QorIQ SDK V1.4?

Hi All,

 

I have a T4240QDS system that I'm trying to run some FFTs on.  I have downloaded and set up the QorIQ SDK version 1.4 and I have successfully built and loaded a rootfs.  I used the fsl-image-core as a basis and added a few packages.  I'm having some trouble adding the fftw package.  The process I followed is:

 

Run: bitbake fftw to build the package - succeeds

Modify my fsl image recipe file to include fftw

Run bitbake fsl image - also succeeds

 

When I load the image onto the T4240QDS system, I can't find the fftw header file.  I can see it here:

/build_t4240qds-64b_release/tmp/sysroots/t4240qds-64b/usr/include/fftw3.h

 

But it doesn't seem to get into my rootfs.  Also, I installed the fsl-toolchain, but when I try to use its compiler to build a simple fftw application, it tells me it can't find the header file.  I'll admit, I don't fully understand how the toolchain is supposed to work, so perhaps I'm just doing something wrong.  Any and all help is greatly appreciated.

 

Thanks.
