Hi, Thanks for the reply.
Cross tool chain gcc version 4.4.1 supports for atomic instructions but they are part of GLOBAL HIDDEN (obtained when I ran readelf for the libgcc.a), and armv7a architecture also supports atomic instructions, I tried with -march=armv7-a settings in the CFLAGS but got the same error, what else could be problem?

Check your -march settings or whether the architecture supports that at all.
