在Visual Studio中的ASM调用C标准库函数 [英] Call C standard library function from asm in Visual Studio

问题描述

我有在Visual Studio中创建ASM项目（Win10 64时，Visual Studio 2015年）调用C函数的一个问题。项目由一个ASM文件：

I have a problem with calling C function from asm project created in visual studio (Win10 x64, Visual Studio 2015). Project consist of one asm file:

.586
.model flat, stdcall
option casemap:none
includelib msvcrt.lib

ExitProcess PROTO return:DWORD
extern printf:near

.data
text BYTE "Text", 0

.code
main PROC
    push offset text
    call printf
    add esp,4
    invoke ExitProcess,0
main ENDP
end main

当我建的项目，连接器输出错误：

When I build project, linker outputs the error:

错误LNK2019解析的外部符号_printf中引用
  函数_main @ 0

Error LNK2019 unresolved external symbol _printf referenced in function _main@0

连接器输出参数：

如果我评论调用打印，那么一切都将正常执行（甚至是Windows API函数）。有什么办法来调用ASM文件C函数，而无需创建包含CPP文件＆LT; cstdio＆GT; ？
是否有可能呢？

If I comment call print, then everything executes normally (even Windows API function). Is there any way to call C function from asm file without creating cpp file that includes <cstdio>? Is it possible to do?

推荐答案

微软重构大部分的 C 的运行时间和图书馆在2015年VS某些功能不再从出口的 C 的库（有些是在 C 的头文件中定义）。微软有一个像的 legacy_stdio_definitions.lib 的一些兼容性库和 legacy_stdio_wide_specifiers.lib 的，但你也可以选择使用旧的Visual Studio 2013平台工具与旧的 C 的库。

Microsoft refactored much of the C runtime and libraries in VS 2015. Some functions are no longer exported from the C library (some are defined in a C header file). Microsoft has some compatibility libraries like legacy_stdio_definitions.lib and legacy_stdio_wide_specifiers.lib, but you can also choose to use the older Visual Studio 2013 platform toolset with the older C libraries.

要改变平台工具集：在项目菜单拉下来;选择属性... ;转到配置属性 / 常规，并更改平台工具集为的Visual Studio 2013（V120）

To change the platform toolset: pull down the Project menu; select Properties...; go to Configuration Properties/General, and change Platform Toolset to Visual Studio 2013 (v120)
