Module machine type 'x64' conflicts with target machine type 'X86'

  • Hello. Sorry, for very possible lame question but I've read other topics and didn't find a response. Today I downloaded Qt5, exactly Qt 5.1.1 for Windows 64-bit (VS 2012, OpenGL, 522 MB) and install it. Also I've installed MSVC2012 and Qt Add-in for MSVC2012. Then I pointed Qt path and created simple Qt GUI application. But when I trying to run it i geting the error:
    @Qt5Widgetsd.lib(Qt5Widgetsd.dll) : fatal error LNK1112: module machine type 'x64' conflicts with target machine type 'X86'.@ What may be the reason?
    "Here": an autor had similar problem but resolved it but having not explained how. I checked my Qt version, it is actual. I would be very appriciate you for a help.

    are you trying to build an x86 (32bit) application with 64-bit binaries? :)

  • No. What did you mean? When I change target in linker preferencies to x64 I'm getting similar error, x86 conflicts with x64, but with another library.

  • You are using incompatible libraries, some are 32 bit, some (notably Qt) 64. Download and use the 32 bit Qt version, that should work.

  • I downloaded 32 bit Qt and it works. Thanks a lot. It seems some Qt libraries are 32 bit and some (also Qt) are 64. Why? Is it possible to use?
