Compiling C-code from the Command Prompt in Windows?

Question

Hello!

I want to compile C code from the Command Prompt in Windows. I have added the environment variable to the PATH and I can compile .cs files with: csc app.cs

That's OK, but how do I compile app.c?

Answer 1

You do this:

cl app.c

Here's a complete transcript, including setting up the environment for Visual Studio 2005 (change "8" to "9.0" for Visual Studio 2008).

C:\src\tests>"\Program Files (x86)\Microsoft Visual Studio 8\vc\bin\vcvars32.bat"
Setting environment for using Microsoft Visual Studio 2005 x86 tools.

C:\src\tests>type app.c
#include <stdio.h>
int main(void)
{
    printf("Hello world!\n");
    return 0;
}
