推荐答案

如何在 Visual Studio 中使用 x64 程序集文件构建混合源 x64 项目:

1) 启动 Visual Studio (Community) 2015 并选择 FILE - New - Project.

1) Start Visual Studio (Community) 2015 and choose FILE - New - Project.

2) 在下一个窗口中选择Win 32 Console Application.

2) In the next window choose Win 32 Console Application.

3) 你得到一个确认.点击Next>.

3) You get a confirmation. Click on Next >.

4) 在下一个窗口中，您可以接受默认设置.点击Finish.

4) In the next window you can accept the default settings. Click on Finish.

5) 确保该项目在解决方案资源管理器中突出显示，然后从菜单中选择 PROJECT - Build Customizations....

5) Make sure, that the project is highlighted in the Solution Explorer and and choose PROJECT - Build Customizations... from the menu.

6) 在下一个窗口中勾选masm(.targets,.props)并点击OK.

6) In the next window tick masm(.targets,.props) and click on OK.

7) 选择 Build - Configuration Manager...

8) 将 Active solution platform 更改为 x64

8) Change the Active solution platform to x64

9) 创建 callee.asm:PROJECT - 添加新项目.

9) Create callee.asm: PROJECT - Add New Item.

10) 在下一个窗口中选择 C++File(.cpp) 和 - IMPORTANT! - 给它一个带有 .asm 扩展.点击添加.

10) In the next window choose C++File(.cpp) and - IMPORTANT! - give it a name with an .asm extension. Click on Add.

10) 现在检查 .asm 文件是否具有正确的属性.在解决方案资源管理器中右键单击该文件并选择 Properties.

10) Now check if the .asm file has the right properties. In the Solution Explorer right-click on the file and choose Properties.

11) 在属性页中，您至少应该看到:

11) In the Property Page you should see at least:

Excluded From Build    (empty) or No
Item Type              Microsoft Macro Assembler

在Command Line下确保选择ml64.exe作为汇编程序.

Under Command Line ensure that ml64.exe is chosen as the assembler.

点击OK.

12) 现在您可以用内容填充文件了.

12) Now you can fill the files with content.

ConsoleApplication1.cpp:

#include <iostream>
using namespace std;

extern "C" void hello_from_asm();

int main()
{
    cout << "Hello from CPP" << endl;
    hello_from_asm();
    return 0;
}

callee.asm:

PUBLIC hello_from_asm
EXTERN puts:PROC

.data

    hello1 db "Hello from ASM.",0

.code

hello_from_asm PROC
    push rbp
    mov rbp, rsp
    sub rsp, 32                 ; Shadow Space
    and spl, -16                ; Align stack at 16

    lea rcx, hello1
    call puts

    leave                       ; Restore stack (rsp) & frame pointer (rbp)
    ret
hello_from_asm ENDP

END

13) 构建 .exe

13) Build the .exe

并使用 CTRL-F5 运行它.

应用程序将在新窗口中打开.

The application will be opened in a new window.
