在OSX上将库静态链接到C++dylib中

我正在编译许多.dlib（一个插件），我想静态地将tinyxml2包含在其中。我把tinyxml2.cpp和tinyxml2.h放在源旁边。当我运行make时，它产生的命令是：

rm -rf *.a *.os *.dylib
g++-4.0 -g -c -Werror -DUSE_GLEW -I/Applications/Nuke6.3v4/Nuke6.3v4.app/Contents/MacOS/include -isysroot /Developer/SDKs/MacOSX10.5.sdk -arch x86_64 tinyxml2.cpp -o tinyxml2.a

我应该如何使其链接？（我希望我正在构建的所有.dlib都静态地包含tinyxml2-lib，最好是带有名称空间的mangling）。

请注意，我在这里使用的是旧的10.5 SDK，因为我的主机应用程序使用了它，所以我不得不这样做。
