I needed to use usdpaa libraries . So I downloaded the yocto project and installed it.

Then I did the following

$source ./fsl-setup-poky -m t4240qds

went to build directory

$bitbake usdpaa

I found the images and include files in QorIQ-SDK-V1.4-20130625-yocto/build_t4240qds_release/tmp/work/ppce6500-fsl_networking-linux/usdpaa/git-r5/image/usr

copied them to the sytem usr folder but I am unable to compile hello_reflector.c example in the usdpaa apps folder.

says undefined reference to the functions . What is that I am doing wrong .
