Hi all.<br><br>I&#39;ve built a static library that references boost threads, conditions and ptime.&nbsp; All the libraries were build with the following command &quot;bjam --layout=system link=static release debug&quot;, then renamed to something more generic eg. boost_thread-mt.lib for the multi-threaded release version of the thread library.&nbsp; Now I know I did get the static libraries and not the DLL bridges because it was originally named libboost_thread-mt.lib.&nbsp; Actually I also used the --buildid command to add something other than -1_35, but I don&#39;t think that really matters.&nbsp; Anyway, the Win32 version of my project is built using VS2008, so I have a top level include file that defines BOOST_ALL_NO_LIB to prevent auto-linking.&nbsp; I then explicitly link the libraries that I need and build my project library.&nbsp; I assume it&#39;s actually linking everything in successfully since the output lib is vastly larger when I link the libs than when I don&#39;t.<br>
<br>Now the real problem comes when I try to link to this library in my test application.&nbsp; I&#39;ve switched up whether it is the lib or the application that defines BOOST_ALL_NO_LIB, and who actually links to the libraries etc.&nbsp; I&#39;ve also made sure that they&#39;re all using the same run-time build settings eg. /MTd for both my lib and app, which would link to the -mt-gd version of the boost libraries.&nbsp; No matter what I do, I get a bunch of warnings about using locally defined symbols (changing which one links the libraries just changes whether the warning originates from my lib or boost&#39;s) and a few unresolved externals.&nbsp; They look something like this:<br>
<br>Common.lib(thread.obj) : warning LNK4217: locally defined symbol ??0id@locale@std@@QAE@I@Z (public: __thiscall std::locale::id::id(unsigned int)) imported in function &quot;void __cdecl `dynamic initializer for &#39;public: static class std::locale::id boost::date_time::date_facet&lt;class boost::gregorian::date,char,class std::ostreambuf_iterator&lt;char,struct std::char_traits&lt;char&gt; &gt; &gt;::id&#39;&#39;(void)&quot; (??__E?id@?$date_facet@Vdate@gregorian@boost@@DV?$ostreambuf_iterator@DU?$char_traits@D@std@@@std@@@date_time@boost@@2V0locale@std@@A@@YAXXZ)<br>
<br>Common.lib(thread.obj) : error LNK2019: unresolved external symbol __imp___beginthreadex referenced in function &quot;private: void __thiscall boost::thread::start_thread(void)&quot; (?start_thread@thread@boost@@AAEXXZ)<br>
<br>If I&#39;m not mistaken, LNK4217 means that the linker believes the symbol is local, but it&#39;s using a different calling convention, almost like it thinks it&#39;s importing from a DLL.&nbsp; I could suppress those by compiling against the Common Language Runtime, but somehow I think that I&#39;m seeing these might be the root of my problem.&nbsp; Any thoughts?<br>
<br>All I really want to be able to do is have an external app link to my libraries without having to also link to boost.&nbsp; I can only assume that I&#39;m either not linking them into my library properly or that I&#39;m not using the right boost defines.&nbsp; It&#39;s probably something really simple that I&#39;m missing, but it&#39;s been driving me crazy and I&#39;m just not getting anywhere.&nbsp; Any help would be appreciated.<br>
<br>Thanks in advance,<br>Darren Mason<br>
