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??
(1)文件->新建->项目->Visual C++->Win32控制台应用程序
名称中输入项目的名称
确定->下一步->空项目->完成
(2)解决方案资源管理器 中 源文件 右击
添加->新建项->代码->C++文件(.cpp)
名称中输入 某某文件名.c 不要.cpp
添加
(3)项目->项目名 属性->C/C++->高级->编译为
选择 编译为C代码(/TC)
确定
