Description

MSCV assembler ML and ML64 command-line reference Syntax

ML [ options ] filename [ [ options ] filename ]

cpp.assemblerFlags are placed after the filename, so they are ignored by ML.exe. Only predefined "/nologo" "/c" "/Fo" is valid but cpp.assemblerFlags are not .

See windows-msvc-base.qbs (line 323, Rule of inputs:"asm" )

var args = ["/nologo", "/c",
     "/Fo" + FileInfo.toWindowsSeparators(output.filePath),
     FileInfo.toWindowsSeparators(input.filePath)];
if (product.cpp.debugInformation)
     args.push("/Zi");
args = args.concat(Cpp.collectMiscAssemblerArguments(input, "asm"));

My Example is:

CppApplication { 
  targetName: "test"    
  files: "1001.asm"    
  cpp.compilerIncludePaths: "C:/Masm32/Include"    
  cpp.assemblerFlags: ["/I", "C:\\Masm32\\Include"]
}

qbs build output:

assembling 1001.asm [project]
ERROR: "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.16.27023\bin\HostX86\x86\ml.exe" /nologo /c /FoC:\Users\98581\Desktop\QBS_Project\E1\default\project.98f54143\3a52ce780950d4d9\1001.asm.obj C:\Users\98581\Desktop\QBS_Project\E1\1001.asm /Zi /I C:\Masm32\Include

ERROR: Process failed with exit code 1.
The following products could not be built for configuration default:
project

If the argument ("/I C:\Masm32\Include") is ahead of the file path (***\1001.asm), it would be build successfully.

My suggestion is to put "FileInfo.toWindowsSeparators(input.filePath)]" to the last element of args.

(file: windows-msvc-base.qbs, line: 323, Rule of asm)

var args = ["/nologo", "/c",  "/Fo" + FileInfo.toWindowsSeparators(output.filePath)];
args = args.concat(Cpp.collectMiscAssemblerArguments(input, "asm"));
if (product.cpp.debugInformation)
      args.push("/Zi");
args.push(FileInfo.toWindowsSeparators(input.filePath));
var cmd = new Command(product.cpp.assemblerPath, args);
