Fatal error Lnk1112:module machine type ' X86 ' conflicts with Target machine type ' x64 '

Xxxxxx.lib (xxxxxx.obj): Fatal error Lnk1112:module machine type ' X86 ' conflicts with Target machine type ' x64 '

1. First to see if your module is 64-bit , this is generally, how to configure 64-bit project, here do not say;

2. See if the module is linked to a static library or whether the DLL is 64-bit ;

Configuration-->kinker-->general-->additional Library directories Look is linked to the 64-bit directory;

Whether the library in configuration-->kinker-->input-->additional Dependencies is 64 bits;

3. See if your linked libraries are all 64-bit compiled , temporary files, and whether the target files are generated to a 64-bit directory;

4. Look at the static library of your links :

Configuration-->librarian-->general-->additional Dependencies

Configuration-->librarian-->general-->additional Library Directories

Whether there is a dependency on 32-bit content, in fact, the static library does not need to link the static library, I just because the static library to rely on 32-bit, resulting in 64-bit module compilation failure.

5. Finally, try changing this place :

Configuration-->preprocessor-->preprocessor Definitions-->win32 changed to _win64

Summarize:

Xxxxxx.lib (xxxxxx.obj): Fatal error Lnk1112:module machine type ' X86 ' conflicts with Target machine type ' x64 '

This error message tells you that the 64-bit module relies on 32-bit things to make sure that you rely on a library that is 32-bit, and that the library you rely on doesn't contain anything else 32 bits.
