I'm using boost_regex 1.28.0 with STLport 4.5.3 on Solaris using Forte compiler. When I build with -g option, it fails at linkage with the following errors ild: (undefined symbol) boost::detail::allocator<unsigned char>::allocator<char>#Nvariant 1(const boost::detail::allocator<__type_1>&) -- referenced in the text segment of ../../../../packages/boost_1_28_0/sparc-solaris/libboost_regex_mt.a(OhCenAP7d5aN-_Bfr3wh.o) ild: (undefined symbol) boost::detail::allocator<unsigned char>::allocator<char>#Nvariant 1(const boost::detail::allocator<__type_1>&) -- referenced in the text segment of ../../../../packages/boost_1_28_0/sparc-solaris/libboost_regex_mt.a(J-U5NXbbfexb9iPLelyN.o) ild: (undefined symbol) boost::detail::allocator<unsigned char>::allocator<char>#Nvariant 1(const boost::detail::allocator<__type_1>&) -- referenced in the text segment of ../../../../packages/boost_1_28_0/sparc-solaris/libboost_regex_mt.a(5cVinizdRsfQ1ujqbKlp.o) ild: (undefined symbol) boost::detail::allocator<unsigned char>::allocator<char>#Nvariant 1(const boost::detail::allocator<__type_1>&) -- referenced in the text segment of ../../../../packages/boost_1_28_0/sparc-solaris/libboost_regex_mt.a(TbU7jVI0o3rCSz-c48HV.o) ild: (undefined symbol) boost::detail::allocator<unsigned char>::allocator<char>#Nvariant 1(const boost::detail::allocator<__type_1>&) -- referenced in the text segment of ../../../../packages/boost_1_28_0/sparc-solaris/libboost_regex_mt.a(Zi2bUcR97vUxCHzFzV0a.o) ild: (undefined symbol) boost::detail::allocator<unsigned char>::allocator<char>#Nvariant 1(const boost::detail::allocator<__type_1>&) -- referenced in the text segment of ../../../../packages/boost_1_28_0/sparc-solaris/libboost_regex_mt.a(aTM7t-gA2lwhiyP5RH3P.o) ild: (undefined symbol) boost::detail::allocator<unsigned char>::allocator<char>#Nvariant 1(const boost::detail::allocator<__type_1>&) -- referenced in the text segment of ../../../../packages/boost_1_28_0/sparc-solaris/libboost_regex_mt.a(OkRWOOTWnnv97gH0a9t_.o) ild: (undefined symbol) boost::detail::allocator<unsigned char>::allocator<char>#Nvariant 1(const boost::detail::allocator<__type_1>&) -- referenced in the text segment of ../../../../packages/boost_1_28_0/sparc-solaris/libboost_regex_mt.a(hKZggW9H89qzPd1td_2e.o) ild: (undefined symbol) boost::detail::allocator<unsigned char>::allocator<char>#Nvariant 1(const boost::detail::allocator<__type_1>&) -- referenced in the text segment of ../../../engine/lib/sparc-solaris/ Any idea what's going on? Everything works fine without -g option. ____________________________________________________________ Yahoo! Messenger - Communicate instantly..."Ping" your friends today!
