Hello, I'm using Boost 1.42, IBM XL C++ 10.1, and AIX 5.3. I'm running into trouble building code that uses Boost.PropertyTree. I get errors compiling the following code, which works fine on numerous other platforms: boost::property_tree::ptree pt; pt.put(LOG_FILE_KEY, props.log_file_name()); pt.put(LOG_LEVEL_KEY, props.log_level()); pt.put(LOG_NAME_KEY, props.log_name()); pt.put(LOG_FILE_SIZE_MAX_KEY, props.log_file_max_size()); pt.put(LOG_TO_CONSOLE_KEY, props.log_to_console()); pt.put(MESSAGE_MAX_KEY, props.message_max_size()); pt.put(SCAN_THREADS_KEY, props.scan_threads()); std::ostringstream prop_info; boost::property_tree::ini_parser::write_ini(prop_info, pt); The errors, all of which are attributed to the last line of code above, are: "/home/wmason/src/cap-aix/fim/../opt/include/aix/boost/v1.42/boost/property_tree/detail/ptree_implementation.hpp", line 55.28: 1540-0129 (S) The qualifier "subs" is not defined in the current scope.

The release notes for Boost 1.42 at http://www.boost.org/users/news/version_1_42_0 claim that my combination of OS, compiler and Boost version are supported. I was wondering if anyone might know of a way around this problem besides not using Boost.PropertyTree. Thanks very much for any help, Will
