Question

我正在使用masm32来编译和链接在Windows 7上，这可以很好地使用下面的代码。但是，调用stdOut并不是简单地在命令提示符下打印任何东西。我做错了什么？

.386

.model flat, stdcall
    option casemap:none

    include C:\masm32\include\windows.inc
    include C:\masm32\include\kernel32.inc
    include C:\masm32\include\user32.inc
    include C:\masm32\include\masm32.inc

    includelib C:\masm32\lib\kernel32.lib
    includelib C:\masm32\lib\user32.lib
    includelib C:\masm32\lib\masm32.lib

.data    
    MsgBoxCaption   db "Message Box Caption", 0
    MsgBoxText      db "Win32 Assembly is great!", 0

.data? 
    ; declare an uninitialized byte, referred to as location sum
    sum             dd ?

.code
    start:    
        mov eax, 1d
        mov ebx, 1d

        ; result will be stored in the first argument
        add eax, ebx  

        ; push eax onto the stack
        push eax

        ; pop value into sum
        pop sum

        ; invoke MessageBox, NULL, addr MsgBoxText, addr MsgBoxCaption, MB_OK

        invoke StdOut, addr MsgBoxCaption
        invoke StdOut, addr sum

        ; exit with status code 0 
        invoke ExitProcess, 0
    end start

解决了...我正在使用错误的链接器参数

如何正确链接

ml /c /coff /Cp hello.asm
link /subsystem:console /libpath:c:\masm32\lib hello.obj

如何不链接此程序

ml /c /coff /Cp hello.asm
link /subsystem:windows /libpath:c:\masm32\lib hello.obj

masm32调用stdout没有输出
