Hi,<br>I&#39;m trying to build app which uses some shared library (BMS) depending on boost_thread:<br>- gcc 3.4.3 on Linux 32bit (native build - no cross compilation)<br>- boost 1.34.1 + STLport 5.0<br><br>Boost is build from scratch with STLport like this:<br>

./bjam -a -j 8 stdlib=stlport threading=multi --without-python stage <br><br>tools/build/v2/tools/stlport.jam is modified slightly to disable libstlport.so suffixes (two lines outcommented appending _gcc and/or _stldebug) rather to modify the target machine.<br>

<br>BOOST builds fine (not everything, spirit for example, but it&#39;s not used in the app so I didn&#39;t bother). However, building an app reports unresolved symbol, which should be in boost_thread library. Build scripts are ok - used in the past with BOOST and native STL (and they work with BOOST 1.35 + STLport!), libraries are found... here is a part of app build command line:<br>

<br>usr/bin/c++   -O3 ...  -o bms_ctrl -rdynamic -L/paths... -lboost_thread-gcc34-mt-p-1_34_1 ...<br><br>Which reports an error:<br>BMS/lib/Linux-2.6/libBMS.so: undefined reference to `boost::thread::thread(boost::function0&lt;void,stlp_std::allocator&lt;boost::function_base&gt; &gt; const&amp;)&#39;<br>

<br>Analysing the libboost_thread-gcc34-mt-p-1_34_1.so I couldn&#39;t found anything similar to undefined symbol referenced in BMS library:<br>&#39; U _ZN5boost6threadC1ERKNS_9function0IvN8stlp_std9allocatorINS_13function_baseEEEEE&#39;<br>

<br>If possible (problem is solved), we would prefer boost 1.34.1 over 1.35.0. Any idea / hint is very much appreciated.<br><br>Thanks in advance,<br>Damjan<br>
