Static build error because of libstdc++ "multiple definitions"
I tried to build OpenCV 2.4.9 static libraries with sources from Windows download and compiler TDM-GCC (MinGW32, GCC 4.8.1). In CMake configuration i just unchecked BUILD_SHARED_LIBS (from default).
While compiling the libraries only works, executing the "all" build tries to compile applications which results in errors because of multiple definitions in libstdc++.a and libstdc++.dll.a.
As background: TDM-GCC links runtimes statically by default. The compilation of OpenCV applications shows the flag "-libstdc++", which forces dynamic linking, while the linked libraries have the static runtime linked -> conflict!
