Hi,

I am trying to use boost serialization library, but run into link
errors that I don't know how to resolve.

I created a very simple data structure with a 'string' and 'int' in
it. Then I try to serialize it to a stringstream and recover from a
stringstream. The compile failed during linking. The first few errors
are:

% make
g++ -O0 -g3 -Wall -D_REENTRANT -pthread -lboost_program_options
-lboost_filesystem -lboost_iostreams -lboost_thread -lboost_regex

......

I attached the source code of the 4 files I use: main.cpp,
SimpleData.h, SimpleData.cpp, and Serialize.cpp. Also, here is the g++
version I use:

% g++ -v
Using built-in specs.
Target: i486-linux-gnu
Configured with: ../src/configure -v
--enable-languages=c,c++,fortran,objc,obj-c++,treelang --prefix=/usr
--enable-shared --with-system-zlib --libexecdir=/usr/lib
--without-included-gettext --enable-threads=posix --enable-nls
--program-suffix=-4.1 --enable-__cxa_atexit --enable-clocale=gnu
--enable-libstdcxx-debug --enable-mpfr --enable-checking=release
i486-linux-gnu
Thread model: posix
gcc version 4.1.2 (Ubuntu 4.1.2-0ubuntu4)

Is there something I missed in the include list? I tried '#include
<boost/archive/detail/basic_oarchive.hpp>' in Serialize.h file, that
would trigue compile error even before linking.

Thanks,

Yu
