I wrote a C++ project with some assembly code files in it. The project files include a C++ file with a main function, and a test.asm file.

I configured the project according to the method of this link (external assembly file in visual studio). When I try to build the project, an error occurs.

Here is the file test.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

I tried to build the project with both Visual Studio 2022 and x64 Native Tools Command Prompt for VS 2022 and got same error.

  • `'ml64.exe' is not recognized as an internal or external command, operable program or batch file.` Is it able to locate your assembler? – Irelia Mar 11 '22 at 06:05
  • I can't find on the web whether Community Edition is supposed to include the assembler or not. If msbuild expects to find it, then it should be there. – Tim Roberts Mar 11 '22 at 06:11
  • Yes community edition includes it, I think you just need to specifically set a path for it. – Irelia Mar 11 '22 at 06:35
  • What if you try compiling 32 bit instead of 64? – Irelia Mar 11 '22 at 06:35
  • I tried compiling 32bit and 64bit but both failed – ZSY-ARCH Mar 11 '22 at 06:47
  • I can manually type ml64.exe /c /nologo /Zi /Fo"x64\Debug\test.obj" /Fl"" /W3 /errorReport:prompt /Tatest.asm to compile test.asm, but typing msbuild to compile the project fails – ZSY-ARCH Mar 11 '22 at 06:52
  • What is the error in Visual Studio. Are there any errors from editor before `build`? `for .NET Framework` This doesn't look like C++. – Minxin Yu - MSFT Mar 11 '22 at 08:28

    Visual Studio has a modular install these days. The assembler won't be in default installs, since pretty much nobody writes assembly these days. – MSalters Mar 11 '22 at 09:28
