Hi,<br />
<br />
Thanks for the reply.<br />
<br />
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?<br />
<br />
With Best Regards,<br />

The problem is that the code wants to use an atomic instruction that GCC<br />
<br />
doesn't have a builtin for. Check your -march settings or whether the<br />
<br />
architecture supports that at all.<br />
