Using msvc lib in mingw

I have hardware (xray sensor) which has development tools. but afaiu they are built in msvc. so i have a .lib file and a dll file. if I include this lib file in my project (I use qt) and put the dll file in the exe folder and compile it using the MSVC-Release everytihng option. But when I try to compile using the mingw-Release option. he fails.

undefined link to `imp__ZN6IDcDrv6CreateEPKci '

undefined reference to `imp__ZN6IDcDrv14GetDeviceCountEv '

can you specify some way out so i can use these libs. and dll using the mingw compiler

ps: i tried and failed impdef dclibsn.dll> dclib.def

dlltool -dllname dclibsn.dll --def dclib.def --output-lib libdclibsn.a

and so my def file looks like

LIBRARY "dclibsn.dll"
EXPORTS
??0DcDrv@@QAE@ABV0@@Z
??0DcDrv@@QAE@V?$CStringT@DV?$StrTraitMFC_DLL@DV?$ChTraitsCRT@D@ATL@@@@@ATL@@@Z
??0IDcDrv@@QAE@ABV0@@Z
??0IDcDrv@@QAE@XZ
??1DcDrv@@QAE@XZ
??4DcDrv@@QAEAAV0@ABV0@@Z
??4IDcDrv@@QAEAAV0@ABV0@@Z
?CaptureImage@DcDrv@@AAE_NHHHK_NHH@Z
?CloseUsbDevice@DcDrv@@AAE_NXZ
?ColumnDefectComp@DcDrv@@AAEGPBGH@Z
?CompensationImage@DcDrv@@AAEXPAGQAEHH@Z
?Create@IDcDrv@@SAPAVDcDrv@@PBDH@Z

Pay attention to the last entry in this file (Create.) I try to call this in a program, and I get

(.text+0x1ad): undefined reference to `_imp___ZN6IDcDrv6CreateEPKci'

and if I replace the string? Create @IDcDrv @@ SAPAVDcDrv @@ PBDH @Z

with imp__ZN6IDcDrv6CreateEPKci compiles, but gives an error.

The procedure entry point _ZN6IDcDrv6CreateEPKci could not be located in the dynamic link library dclibsn.DLL.

See this: How to use libraries compiled with MingW in MSVC?

I mean the #include environment with an external "C" block. Because using extern "C" will instruct the compiler that the functions use the C link, not C ++, which will stop it from doing manipulation of function names.

Entry point error because you probably don't have the main () in your dll. Just add one (even if its empty, it doesn't matter) and this error will disappear.
