Hi,
I got an error when building OpenOffice.org on Alpha EV6 platform, the error log is as following:
Compiling: comphelper/unxlngaxp.pro/misc/comphelp4gcc3_version.c Making: comphelper.lib Making: libcomphelp4gcc3.so ../unxlngaxp.pro/slo/enumberablemap.o: In function 'comphelper ::EnumerableMap ::initialize(com::sun::star::uno::Sequencecom::sun::star::uno::Any const&)': '__sync_fetch_and_add_4' undefined reference ... These functions are built-in functions provided by gcc to implement atomic operations. For some platforms, these intrinsics were not implemented.. You can either provide an implementation yourself, or use a newer version of gcc that implements them.
Yes. To disable shared_ptr's use of these intrinsics, #define BOOST_SP_USE_PTHREADS.
