Relocation Error, updating kernel

ktjobqt

I'm upgrading my Embedded Linux OS from 2.6.10 to 2.6.18 and had to rebuild Qt for the updated kernel. However, I can't get a simple example Qt program running on the new OS. I keep getting a relocation error because of the linking. I believe that I cross-built Qt for 2.6.10 and 2.6.18 with the same configuration/options, but I'm not fully sure. When I look at the config.status, they match though. Also, when I do an ldd of the application between the two OSes, it's linked to the multithread tls libs in 2.6.10 but not so in 2.6.18. In both, I didn't add the -thread options. Thoughts?

Do you think this error is Qt related? or is it with my embedded 2.6.18 filesystem?
