undefined references '__sync_fetch_and_add_4 ' for Boost_1_39_0 on Alpha platform
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::Sequence<com::sun::star::uno::Any> const&)': '__sync_fetch_and_add_4' undefined reference ./unxlngaxp.pro/slo/enumberablemap.o: In function 'comphelper::EnumerableMap::initialize(com::sun::star::uno::Sequence<com::sun::star::uno::Any> const&)': '__sync_fetch_and_add_4'undefined reference ../unxlngaxp.pro/slo/enumberablemap.o: In function 'comphelper::EnumerableMap::initialize(com::sun::star::uno::Sequence<com::sun::star::uno::Any> const&)': '__sync_fetch_and_add_4'undefined reference ../unxlngaxp.pro/slo/enumberablemap.o: In function 'comphelper::EnumerableMap::initialize(com::sun::star::uno::Sequence<com::sun::star::uno::Any> const&)': '__sync_fetch_and_add_4'undefined reference ../unxlngaxp.pro/slo/enumberablemap.o: In function 'comphelper::EnumerableMap::initialize(com::sun::star::uno::Sequence<com::sun::star::uno::Any> const&)': '__sync_fetch_and_add_4'undefined reference ../unxlngaxp.pro/slo/enumberablemap.o: more undefined references to '__sync_fetch_and_add_4' follow collect2: ld returned 1 exit status dmake: Error code 1: while making '../unxlngaxp.pro/lib/libcomphelp4gcc3.so' The <boost/shared_ptr.hpp> of Boost_1_39_0 is used here. Is this a bug on Boost_1_39_0 ? and is there already a fix for it? Best Regards, Yan

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. KEVIN ARUNSKI

Yes. To disable shared_ptr's use of these intrinsics, #define BOOST_SP_USE_PTHREADS.

Yes. To disable shared_ptr's use of these intrinsics, #define BOOST_SP_USE_PTHREADS.
Thanks for your kindly replies. It's a little difficult to implement the atomic operations by myself;-) Where should the macro BOOST_SP_USE_PTHREADS be defined ? Which file in boost or the file in my comphelper.cxx? Regards, Yan

You should define it globally, both in your project and in bjam line when you build boost.

You need to define it in each cpp/cxx file that uses shared_ptr. The safest way to do that is to define it globally for the project by, for example, adding -DBOOST_SP_USE_PTHREADS to the build flags.

I added -DBOOST_SP_USE_PTHREADS globally and the compiling passed successfully. Thanks very much for your help. Regards, Yan
I added -DBOOST_SP_USE_PTHREADS globally and the compiling passed successfully. Thanks very much for your help.
Note that if you use some other boost libs, which might use shared_ptr, you have to compile them with this flag as well.
