why linker looks for LIBCMT.lib in x86 directory instead x64?

SETUP

Windows 10

GOAL

I found a library libnodave to communicate through S7-protocol
I'm trying to build examples on x64 architecture through edited makefile

ISSUE

Even though I set directories looking for libraries for x64 (VAR =64), the linker looks for LIBCMT.lib in x86 folder . Why? If i change VAR =86 everything is fine.

crutial part of linking log:
C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.30.30705\lib\x86\LIBCMT.lib : warning LNK4272: library machine type 'x86' conflicts with target machine type 'x64'

Solution

  • The problem was that i was building it with Visual Studio 2022 Developer Command Prompt version x86 that reference wrong nmake.
    I had to process it with x64 that in my case is located here : "C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvars64.bat"
