Hi,Volodya. I'm sorry to trouble you again. At your last respond you suggested me to quote the error message from the compiler. I got the message as following: ...patience... ...found 11853 targets... ...updating 10 targets... gcc.compile.c++ bin.v2/libs/serialization/build/gcc-3.4.3/release/threading-multi/xml_grammar.o In file included from libs/serialization/src/basic_xml_grammar.ipp:22, from libs/serialization/src/xml_grammar.cpp:63: ./boost/spirit/core/primitives/numerics.hpp:122: error: declaration of `template<class ScannerT> struct boost::spirit::sign_parser::result' ./boost/spirit/core/parser.hpp:123: error: conflicts with previous declaration `template<class ScannerT> struct boost::spirit::parserboost::spirit::sign_parser::result' "/opt/SEED_DVS357-SDK/mv_pro_4.0/montavista/pro/devkit/arm/v5t_le/bin/arm_v5t_le-g++" -ftemplate-depth-128 -O3 -finline-functions -Wno-inline -Wall -fPIC -pthread -DBOOST_ALL_NO_LIB=1 -DBOOST_SERIALIZATION_DYN_LINK=1 -DNDEBUG -I"." -c -o "bin.v2/libs/serialization/build/gcc-3.4.3/release/threading-multi/xml_grammar.o" "libs/serialization/src/xml_grammar.cpp" ...failed gcc.compile.c++ bin.v2/libs/serialization/build/gcc-3.4.3/release/threading-multi/xml_grammar.o... ...skipped libboost_serialization-gcc34-mt-1_35.so.1.35.0 for lack of xml_grammar.o... ...skipped

I think that maybe there are some definition conflict in the library, or the gcc kernel(3.4.3) of my cross-compiler is too old. But I still don't know how to deal with these problems. Could you help me? Thanks. with my best wished! Zou --- 09年2月28日，周六, Vladimir Prus 写道：

Hi, Volodya. Thanks for your reply. I have tried the method in the

document (

...

http://www.boost.org/boost-build2/doc/html/bbv2/tasks/crosscompile.html ), there were still some

problems. Some libraries has been built successfully, but many not (such as libboost_serialization, libboost_wave and so on). I got the information as following:

...failed gcc.compile.c++ bin.v2/libs/math/build/gcc-3.8.0/release/link-static/threading-multi/sph_neumannf.o... .......... ...skipped

libboost_serialization-gcc38-mt.a for lack of

libboost_serialization-gcc38-mt-1_38.a...

I didn't know why these libraries built failed. I wonder whether the problem is due to my gcc kernel of cross-compiler . Maybe it's version is too low to build that libraries? How to solve the problem?

Please quote the error message from the compiler, not the diagnostic message from Boost.Build.
