I'm trying to link my "universal binary" program statically with both Boost and libstdc++-static.a to make the distribution easier, because, as I understand, /usr/lib/libstdc++.6.dylib isn't always there, especially, in versions prior to OSX-10.4 I can build Boost apparently successfully, but linking the regex example statically with libstdc++ causes errors. Perhaps someone here could point out what I'm doing wrong (if anything). Here's what I did to build "universal binary" Boost and compile the example (Btw, the documentation could use some clarity about the recipe): (1) Make sure "g++ --version" says i686-apple-darwin8-g++-4.0.1 (symlinks and PATH adjustments to avoid v3.3) (2) ../../bjam --prefix=~/local --build-dir=~/boost_build toolset=darwin link=static \ threading=multi architecture=combined stage install (I also tried adding runtime-link=static with similar results, see below) (3) g++ -static-libgcc -I ~/local/include/boost-1_38 example.cpp \ -o example /usr/lib/libstdc++-static.a ~/local/lib/libboost_regex-xgcc40-mt.a (I tried skipping /usr/lib/libstdc++-static.a, in which case the binary builds, but is linked with /usr/lib/libstdc++.6.dylib) The errors I get here take up many pages and start like this: /usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: warning multiple definitions of symbol std::codecvt<char, char, __mbstate_t>::~codecvt() /usr/lib/libstdc++-static.a(codecvt.o) private external definition of std::codecvt<char, char, __mbstate_t>::~codecvt()in section (__TEXT,__tex t) /usr/lib/gcc/i686-apple-darwin8/4.0.1/libstdc++.dylib(single module) definition of std::codecvt<char, char, __mbstate_t>::~codecvt() /usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: warning multiple definitions of symbol std::codecvt<char, char, __mbstate_t>::~codecvt() /usr/lib/libstdc++-static.a(codecvt.o) private external definition of std::codecvt<char, char, __mbstate_t>::~codecvt()in section (__TEXT,__tex t) /usr/lib/gcc/i686-apple-darwin8/4.0.1/libstdc++.dylib(single module) definition of std::codecvt<char, char, __mbstate_t>::~codecvt() When I use Boost built with "runtime-link=static", the errors look like this instead: /usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: warning multiple definitions of symbol std::codecvt<char, char, __mbstate_t>::~codecvt() /usr/lib/libstdc++-static.a(codecvt.o) private external definition of std::codecvt<char, char, __mbstate_t>::~codecvt()in section (__TEXT,__tex t) /usr/lib/gcc/i686-apple-darwin8/4.0.1/libstdc++.dylib(single module) definition of std::codecvt<char, char, __mbstate_t>::~codecvt() /usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: warning multiple definitions of symbol std::codecvt<char, char, __mbstate_t>::~codecvt() /usr/lib/libstdc++-static.a(codecvt.o) private external definition of std::codecvt<char, char, __mbstate_t>::~codecvt()in section (__TEXT,__tex t) Any suggestions?
