VERY simple C program won't compile with VC 64

Question

Here is a very simple C program:

#include <stdio.h>

int main (int argc, char *argv[]) {

    printf("sizeof(short) = %d\n",(int)sizeof(short));
    printf("sizeof(int) = %d\n",(int)sizeof(int));
    printf("sizeof(long) = %d\n",(int)sizeof(long));
    printf("sizeof(long long) = %d\n",(int)sizeof(long long));
    printf("sizeof(float) = %d\n",(int)sizeof(float));
    printf("sizeof(double) = %d\n",(int)sizeof(double));

    return 0;
}

While it compiles fine on Win32 (command line: cl main.c), it does not using the Win64 compiler ("c:\Program Files(x86)\Microsoft Visual Studio 9.0\VC\bin\amd64\cl.exe" main.c). Specifically, it sais "error LNK2019: unresolved external symbol printf referenced in function main". As far as I understand this, it can not link to printf, right?

Obviously, I have Microsoft Visual C++ Compiler 2008 (Standard enu) x86 and x64 installed and am using the 64-bit flavor of Windows (7).

What is the problem here?

UPDATE:
OK, now I ran vcvarsall.bat amd64. It sais "The specified configuration type is missing. The tools for this configuration might not be installed.". As mentioned, the compiler clearly is installed??

Answer 1

Are you on a 32bit or 64bit system? I'm guessing from the path that the 64bit standard libraries aren't available, at least not in that directory.

Answer 2

There's something wrong with your setup. It compiles & link fine for me.

Did you run vcvarsall.bat with the right options to set up the environment variables before you try running cl.exe? Something along the line of

"C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\vcvarsall.bat" x86_amd64

Answer 3

If you look at vcvarsall.bat it will print the specified configuration missing statement if certain batch files are missing.

For the amd64 option this file must exist:

C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\amd64\vcvarsamd64.bat
