[Boost-users] boost regex, stlport and icu on linux

Hello,

I'm building boost 1.34.1 on linux (with redhat 9 gcc 3.2.2-5) with 
STLport 5.0 and ICU. This is the bjam invocation:

bjam -q -j4 --toolset=gcc \
  --build-dir=~/boost/build \
  --stagedir=~/boost/stage --prefix=~/build-gecko \
  -sNO_BZIP2=1 \
  -sSTLPORT_VERSION=5 -sSTLPORT_5_PATH=~/build-gecko/lib \
  -sSTLPORT_INCLUDE_DIRECTORY=../include/stlport \
  -sSTLPORT_LIB_DIRECTORY=. \
  -sHAVE_ICU=1 -sICU_PATH=~/build-gecko \
  --without-python \
  runtime-link=shared variant=release \
  instruction-set=i686 threading=multi stage install

This simple example:

#include <iterator>
#include <boost/regex.hpp>
#include <iostream>

int main(int argc, const char** argv)
{
     std::string xml_str = "<?xml version=\"1.0\"?><test/>\n";

     boost::regex e1("<\\?xml version=\"[^\"]+\"\\?>",
                     boost::regex::extended);
     std::string sanitized_xml =
         boost::regex_replace(
             xml_str, e1, "",
             boost::regex_constants::match_default
                 | boost::regex_constants::format_literal);
     return 0;
}

compiles ok with

c++  -c -o ./test.o  -mcpu=pentiumpro -march=pentiumpro -pipe -O2 \
   -g3 -pthread -fforce-addr -fstrict-aliasing -Wall -W -Wcast-align \

   -I${HOME}/build-gecko/include \
   -I${HOME}/build-gecko/include/boost-1_34_1 \
   ./test.cc
# Yes, I know the command line is longer than the example

but fails when linking with

c++  -pthread -Wl,-rpath-link,${HOME}/build-gecko/lib \
   -o ./test ./test.o \
   ~/build-gecko/lib/libboost_regex-gcc32-mt-1_34_1.so \

   ~/build-gecko/lib/libicui18n.so \
   ~/build-gecko/lib/libicudata.so \

I googled a bit and found this:

http://lists.boost.org/boost-users/2006/02/17394.php

but there was no follow up. Is there some mistake in my example? Does 
somebody have any suggestions or workarounds? I know that gcc 3.2.2 is 
quite old but I have used it for many years and always convinced it to 
do its work (and no, I cannot easily switch to a newer compiler).

Any help will be really appreciated; cheers,
Michele
