"libgcc_s_sjlj-1.dll" is missing

I am trying to run my first SFML application. I can run it via Code Blocks environment, but I can't run it through the Explorer - an error appears that says: "libgcc_s_sjlj-1.dll is missing". I added these lines to my linker options:

-static
-static-libgcc
-static-libstdc++

However, after trying to compile it, I see an error in the build log:

mingw32-g++.exe: error: unrecognized command line option '-static-libstdc++'

How can I fix it? My GCC version is 4.7.1 TDM-1
