undefined reference to `std::....

You must link against the relevant importlibs.  Here libstdc++

Means:
gcc -shared -Wl,--out-implib=common.dll.a -o common.dll *.o \
-Wl,--export-all-symbols -lstdc++

For libstdc++ this is done automatically if you use g++:
g++ -shared -Wl,--out-implib=common.dll.a -o common.dll *.o \
-Wl,--export-all-symbols
