c - How to compile x64 code with Visual Studio in command line?

Question

I want to compile a simple hello-world-style program using the Windows command line.

cl file_name.c

is easy enough. Now I want to do the same thing in 64 Bit. What should I do?

Answer 1

You need to use a version of the cl.exe compiler which emits x64 code. Which one depends a bit on your setup.

Let's consider the case you're on a 64 bit machine. For this you'll need to use the compiler which lives at

c:Program Files (x86)Microsoft visual Studio 10.0VCinamd64cl.exe

If you're on a 32 bit machine you'll need to use the cross compiler located at

c:Program FilesMicrosoft Visual Studio 10.0VCinx86_amd64cl.exe
