So Added all the additional libraries but still get error in the output:

`warning LNK4272: library machine type 'x64' conflicts with target machine type 'x86'`

This means that glfw3.lib you’re using is built for 64-bit code. But the code you are linking is built as 32-bit code - the `Win32` selection on `Platform` drop-down means you’re looking at 32-bit build. Either switch to `x64` platform to build 64-bit code. Or get 32-bit glfw3.lib file if you want to build 32-bit executable.

Thank you so much, I accidently downloaded the 64-bit code instead of the 32-bit. Thanks once again 😃

Isn’t it possible to build GLFW in 32 bit? I change the compiler in the visual studio setting, it doesn’t build in x86. By default, there is no x86 drop down menu in visual studio.

Am I missing something?

I have cmake 3.27.6.

Hi @jokoon,

Welcome to the GLFW forum.

CMake has recently switched to defaulting the Visual Studio generator to 64bit. To select 32bit you need to specify the target platform, for example with `-A Win32`.

See:
