FFTW

Former Member

Attempting to cross compile and link the fftw library and use it on the zedboard. Not there yet but here's what I've got:

xilinx/linux cross compiled to create a fftw library on my host linux box.
Found a test program and created a test application.
Cross compiled, linked, ftp'd the test executable over to the zedboard.
The zedboard generated an error messages indicating that glibc needed version 15, but found version 11.

According to the xilinx website glibc is not xilinx specific, so I am going to try to cross-compile/update glibc on the zedboard.

wish me luck. Uh-oh, second thoughts...

Any possibility of side-effects? Will attempting to update glibc without the other libraries cause untold pain and suffering?

    To test my ability to remake the kernel and ramdisk I used the xilinx tools.
    I tried the new kernel with the old ramdisk. That failed. I was able to recover using uboot.
    I tried the old kernel with the new ramdisk image. That failed too.
    There is no one place for consistent step by step documentation for building
    the kernel from scratch for the zedboard using xilinx tools.
    My mistakes could have happened at any stage.
    I hope Linaro goes better.
