Hi All, I am getting compilation errors when I try to build my application code which includes some boost headers using IBM XL C/C++ compiler V12.1. ------------------------------------------------------------------------------------------------ "/opt/boost/include/boost/date_time/time_resolution_traits.hpp", line 71.21: 1540-0063 (S) The text "->" is unexpected. "/opt/boost/include/boost/date_time/time_resolution_traits.hpp", line 135.33: 1540-0040 (S) The text "<" is unexpected. "time_resolution_traits" may be undeclared or ambiguous. "/opt/boost/include/boost/date_time/time_resolution_traits.hpp", line 136.33: 1540-0040 (S) The text "<" is unexpected. "time_resolution_traits" may be undeclared or ambiguous. "/opt/boost/include/boost/date_time/time_resolution_traits.hpp", line 137.33: 1540-0040 (S) The text "<" is unexpected. "time_resolution_traits" may be undeclared or ambiguous. "/opt/boost/include/boost/date_time/posix_time/posix_time_config.hpp", line 40.44: 1540-0040 (S) The text "<" is unexpected. "date_time::time_resolution_traits" may be undeclared or ambiguous. ------------------------------------------------------------------------------------------------- These errors seems come due to the fact that this version of compiler is claimed to have more standard conformance than its predecessors. I confirmed from boost release notes of boost 1.50.0 that V12. of XL C/C++ supports this boost version. But still I encountered above errors. Should I use an older version of XL C/C++ compiler so that such errors can be avoided ? Does anybody encountered similar issues ? I am completely stuck at this point and would greatly appreciate any ideas to understand and resolve this.
