visual studio 17 lnk1112 error module machine type 'arm' conflicts with target machine type 'x64'

In the file extApiPlatform.obj, there are following unresolved symbols: close_shared_memory, set_shared_memory_name, map_shared_memory, set_shared_memory_size and destroy_shared_memory (all seem to be defined in shared_memory.c, which is located in common, so all symbols should have already been defined in the build, if I'm not mistaking). The configuration is on release and the target machine is MachineARM64, but for some reason this results in 6 linking errors (LNK2001).

I followed your steps, opened the remoteApiSharedLib-64.vcxproj project, changed the platform to ARM64 and made sure that in the preferences C/C++ the three repositories are added to the additoinal include directories (only common was missing).

The property sheet in VS2010+ will be specific to the obj and the platform so you can inspect the library directories being used to verify that they are not 32 bit.Thank you for your detailed and quick response. Inspect the custom, pre- and post- build events to see if a x86 tool is being used to assemble it. Usually all that stuff is automated in VS but sometimes there are special build steps that were added in by the developer. Have a look at it and see how it's being compiled. Whatever obj is listed will have some kind source code analog with the same name. You look at the name of the obj file and you'll find the root of your problem there. Usually it goes something like this: SOME_KIND_OF_OBJECT.obj: fatal error LNK1112: module machine type 'X86' conflicts with target machine type 'AMD64' I can speak for your problem because the error message you quoted is incomplete. The linker panics and doesn't know what to do with it, so it breaks your build. This error comes up because something in you build is being compiled in the wrong architecture (say as a x86 binary when everything else is 圆4).
