how to fix QT5.3 &&QT5.7 complier difference

@JiujiuTong Why do you have Qt 4.8.6 related DLLs here:
D:\Qt\4.8.6\bin\libgcc_s_dw2-1.dll D:\Qt\4.8.6\bin\libwinpthread-1.dll D:\Qt\4.8.6\bin\libstdc++-6.dllDid you add D:\Qt\4.8.6\bin to your PATH?

depend libs:
QT5CORED.DLL
QT5GUID.DLL
QT5MULTIMDEIA.DLL
QT5NETWORK.DLL
QT5MULTIMDEIAWIDGETSD.DLL
QT5SERIALPORTD.DLL
QT5WIDGETSD.DLL
QT5XMLD.DLL
QT5XMLPATTERNSD.DLL
LIBGCC_S_DW2-1.DLL
KERNEL32.dll
MSVCRT.DLL
LIBWINPTHREAD-1.DLL
USER32.DLLLIBSTDC++-6.DLL@JiujiuTong "QT5.3 compiler with mingw53_32,no compiler error ,but the App can't startup with an error code" - actually this cannot work, as your Qt 5.3 is built with older MinGW version. You cannot mix binaries built with different compilers.

@jsulm
I'm used to develop program under QT4.8.6,so it contains the path.
is it the reason? i will delete it@JiujiuTong You should not add Qt to PATH if you have more than one version of it.

@jsulm
do you mean that QT5.3 should compile with its default Mingw? -
@JiujiuTong You should not add Qt to PATH if you have more than one version of it.

@jsulm
i removed all QT (MINGW) related PATH, and reboot the OS, it is the same error@JiujiuTong Did you rebuild your project?
And as I said: your Qt 5.3 is built using an older MinGW as you're now using to build your project - this is not going to work. -

yes, i rebuild them, a litter different, the windbg can't startup the program, error qt5guid.dll is missing -

yes, i rebuild them, a litter different, the windbg can't startup the program, error qt5guid.dll is missingtips that the all depend qt5*.dll are missing.
if we can't do this, how can i fix the error:
D:\Users\tong\Documents\FMT_L\png.h:506: error: expected '=', ',', ';', 'asm' or 'attribute' before 'png_const_structrp'
typedef const png_struct * PNG_RESTRICT png_const_structrp;

typedef png_info * PNG_RESTRICT png_inforp;
^
...
