Utilities » Magnum Vulkan Info new in Git master

Displays information about Magnum engine Vulkan capabilities.

This utility is built if MAGNUM_WITH_VK_INFO is enabled when building Magnum. To use this utility with CMake, you need to request the vk-info component of the Magnum package and use the Magnum::vk-info target for example in a custom command:

find_package(Magnum REQUIRED vk-info)

add_custom_command(OUTPUT ... COMMAND Magnum::vk-info ...)

See Downloading and building, Usage with CMake and the Vk namespace for more information.


magnum-vk-info [--magnum-...] [-h|--help] [--extension-strings]
    [--all-extensions] [--features]


  • -h, --help — display this help message and exit
  • --extension-strings — list all extension strings provided by the driver
  • --all-extensions — display extensions also for fully supported versions
  • --features – display also features supported by the device
  • --magnum-... — engine-specific options (see Command-line options for details)
