Dear David
Thanks for your response.
We have installed the correct toolchain as u suggested. We have installed bfin-uclinux-gcc06r2-5 toolchain and also bfin-uclinux-elf-gcc06r2-5 toolchain.
We were able to make the sphinx base without errors but when we tried to run "make clean all" for pocketsphinx the following error showed up----

/usr/local/lib/libsphinxfe.a(fe_interface.o): In function fe_init_dither':/root/Desktop/sphinx/sphinxbase-0.2.1/src/libsphinxfe/fe_interface.c:188: undefined reference togenrand_seed'

make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/root/Desktop/sphinx/pocketsphinx/src'
make: *** [all-recursive] Error 1

We also exported the paths uclinux toolchain bins and sphinxbase bin.
Please help us on it.
Is there any tutorial or documentation for pocketsphinx on uclinux for working on it?

Try running make clean and building it again? It could be the case that you first built it for your desktop system and it is trying to link i386 objects into a library for Blackfin.

I can verify that it builds here using the 06r2-5 toolchain.
