vcvarsall: Setup the environment for cross-compiled native x86 from the x64 host.

vcvarsall

$ vcvarsall x64_x86

try on your machine

The command "vcvarsall x64_x86" is a command used in Microsoft Visual Studio to set up the environment variables necessary for building applications using the specified target architecture, which is a combination of x64 (64-bit) and x86 (32-bit) architectures.

When executed, this command will locate and run the appropriate vcvarsall.bat batch file, which is typically found in the Visual Studio installation directory. This batch file sets up the necessary environment variables such as PATH, INCLUDE, LIB, etc., required for compiling and linking programs.

In this specific command, "x64_x86" specifies the target architecture combination of both 64-bit and 32-bit, allowing you to build applications that can run on both architectures. By running this command, you ensure that the necessary environment variables are correctly set for compiling and linking your code with the intended architecture.
