<span style=" font-size:10pt;font-family:sans-serif">Hi All,</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Thanks so much
for the comments. The problem was Clang that was picking up the system
installed GCC and not the one in the advanced toolchain.</span>
<br><span style=" font-size:10pt;font-family:sans-serif">To address the
issue I used --gcc-toolchain=/opt/at10.0 and now compiles.</span>
<br><span style=" font-size:10pt;font-family:sans-serif">But I have still
a problem while trying to execute.</span>
