Hi all I am trying to build boost v 1.30.0 regex library on a hp machine. The 'syname' output is this: PA-RISC2.0_hpux_11.00_v5.1c I go to the "boost-1.30.0/libs/regex/build" directory and issue a 'make -f gcc.mak' command. I get the following errors: ../src/c_regex_traits.cpp:660: call of overloaded `getlocale(int)' is ambiguous /usr/gcc/3.1/lib/gcc-lib/hppa2.0w-hp-hpux11.00/3.1/include/locale.h:144: candidates are: locale_data* getlocale(int) ../src/c_regex_traits.cpp:62: const char* <unnamed>::getlocale(int) ../src/c_regex_traits.cpp:663: call of overloaded `getlocale(int)' is ambiguous /usr/gcc/3.1/lib/gcc-lib/hppa2.0w-hp-hpux11.00/3.1/include/locale.h:144: candidates are: locale_data* getlocale(int) ../src/c_regex_traits.cpp:62: const char* Here is the gcc version.
