How to build windows binary by mingw?

Hello,
I try to build win binary by mingw64 on Windows10 64bit.
I read a topic Building the client on Windows
I fix Makefiles to work and get ppcoind.exe.
ppcoind.exe is works well. it’s OK.

Next, I try to make ppcoin-qt.exe .
I fix many codes and get qt binary! But it didn’t work…

Please tell me what is wrong?

What error do you recive ?

Thank you for comment.
I don’t get any error code, but binary didn’t work.
And original ppcoin-qt.exe didn’t work after I operate generated ppcoin-qt.exe
