Hi all, i've posted some time ago about a problem about how to serialize valarray with boost. The answer was to use the CVS version. But I have errors when i try to compile it. I downloaded the .rpm version of bjam, and installed it with alien and dpkg (i use Ubuntu). I used this command to launch the compilation : bjam --with-serialization I'm using : g++ (GCC) 3.4.6 (Ubuntu 3.4.6-1ubuntu2) and GNU ld version 2.16.91 2006011 I have many erros like this : `.L454' referenced in section `.rodata' of bin/boost/libs/serialization/build/libboost_serialization.so/gcc/debug/shared-linkable-true/array_binary_oarchive.o: defined in discarded section `.gnu.linkonce.t._ZNK5boost7archive17archive_exception4whatEv' of bin/boost/libs/serialization/build/libboost_serialization.so/gcc/debug/shared-linkable-true/array_binary_oarchive.o and collect2: ld a retourné 1 code d'état d'exécution (ld returned code 1) and at the end : ln -fs "libboost_serialization-gcc-mt-1_35.so.1.35.0" "bin/boost/libs/serialization/build/libboost_serialization.so/gcc/release/shared-linkable-true/threading-multi/libboost_serialization-gcc-mt-1_35.so" ...failed gcc-Link-action bin/boost/libs/serialization/build/libboost_serialization.so/gcc/release/shared-linkable-true/threading-multi/libboost_serialization-gcc-mt-1_35.so... ...skipped <@boost!libs!serialization!build/libboost_wserialization.so/gcc/debug/shared-linkable-true>libboost_wserialization-gcc-d-1_35.so for lack of <@boost!libs!serialization!build/libboost_serialization.so/gcc/debug/shared-linkable-true>libboost_serialization-gcc-d-1_35.so... ...skipped <@boost!libs!serialization!build/libboost_wserialization.so/gcc/debug/shared-linkable-true/threading-multi>libboost_wserialization-gcc-mt-d-1_35.so for lack of <@boost!libs!serialization!build/libboost_serialization.so/gcc/debug/shared-linkable-true/threading-multi>libboost_serialization-gcc-mt-d-1_35.so... ...skipped <@boost!libs!serialization!build/libboost_wserialization.so/gcc/release/shared-linkable-true>libboost_wserialization-gcc-1_35.so for lack of <@boost!libs!serialization!build/libboost_serialization.so/gcc/release/shared-linkable-true>libboost_serialization-gcc-1_35.so... ...skipped <@boost!libs!serialization!build/libboost_wserialization.so/gcc/release/shared-linkable-true/threading-multi>libboost_wserialization-gcc-mt-1_35.so for lack of <@boost!libs!serialization!build/libboost_serialization.so/gcc/release/shared-linkable-true/threading-multi>libboost_serialization-gcc-mt-1_35.so... ...failed updating 4 targets... ...skipped 4 targets... I found no info on google (except that : https://launchpad.net/distros/ubuntu/+source/binutils/+bug/42609) , and I'll be glad to give you more info about my cofiguration if necessary.
