I have set up a cmake project using visual studio 2019. I want to start the debug session with some command line parameters.

To achieve that, I've configured the CMakeLists.txt with the VS_DEBUGGER_COMMAND_ARGUMENTS:

set( VS_DEBUGGER_COMMAND_ARGUMENTS "this" "is" "a" "test" ) set( VS_DEBUGGER_WORKING_DIRECTORY "." )

The first thing my C++ code do is to print out that parameters:

if (argc > 1) { // config_file = argv[1]; for (std::size_t i = 0; i < argc; i++) { std::cout << "argument " << i << ": " << argv[i] << std::endl; } } else { std::cout << "the value of argc is: " << argc << std::endl; }

The problem is that when I run Debug, the output I've always see is the value of argc is 1. I've also tried to modify the launch.vs.json file as appears in this related question:

Adding command line arguments to project

and it doesn't work. Any ideas?

  • I've just done that and keeps on failing. The cmake compiles, and executes, but it seems to ignore these properties. I've selected minimum version for cmake the 3.13 Commented Feb 17, 2022 at 16:45
