your compiler is just not supported by opencv devs (they gave up on this long ago)

if you're a n00b, do yourself a favour, ditch the whole codeblocks/mingw idea entirely and get visual studio community (huge download though) there are prebuilt libs for this on sourceforge.

if you have to use mingw, please try with mingw-64 instead.

again, you won't get anywhere with your current setup.
