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

[kilrbz]

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.

Please add the following sentences into the file meta-oe/meta-oe/recipes-support/fftw/fftw.inc.

PACKAGES =+ "header${PN}"

FILES_header${PN} = "/usr/include/*.h"

Then run the following command, and rebuild the rootfs image, header files will be packaged into rootfs filesystem.

bitbake fftw -c package -f

About the SDK provided Toolchain, please refer to the environment script environment-setup-<arch>-fsl_networking-linux-gnuspe, you could specify the sysroot path as build_t4240qds-64b_release/tmp/sysroots/ in your Yocto build environment.

Hi Yiping,

Thank you for your reply.  I modified the fftw.inc file as you suggested (see below).  I then ran fitbake fftw-c package -f and followed that by rebuilding the rootfs, but I still don't seem to have the header files.  I tried moving the header lines to the bottom of the fftw.inc file and also several different paths for /usr/include/*.h, but nothing seemed to make a difference.  If you have any other suggestions I would be happy to try them.

Thank you.
