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:
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.
