Compile errors in nvml_monitor.cpp

[hlavacs]

Hallo,
one more serious thing, when I follow the build and compile instructions, I get lots of compilation errors in file nvml_monitor.cpp when compiling 02_basic_nvvk.cpp (sorry in German)

C:\data\GitHub\RayTracing\Work2\nvpro_core2\nvgpu_monitor\nvml_monitor.cpp(82,10): error C2065: "NVML_BRAND_NVIDIA_VAPP
S": nichtdeklarierter Bezeichner [C:\data\GitHub\RayTracing\Work2\vk_raytracing_tutorial_KHR\build\nvpro_core2\nvgpu_mo
nitor\nvgpu_monitor.vcxproj]

If I remove these lines in nvml_monitor.cpp at line 83 it compiles:

case NVML_BRAND_NVIDIA_VAPPS:
  return "NVIDIA Virtual Applications";
case NVML_BRAND_NVIDIA_VPC:
  return "NVIDIA Virtual PC";
case NVML_BRAND_NVIDIA_VCS:
  return "NVIDIA Virtual Compute Server";
case NVML_BRAND_NVIDIA_VWS:
  return "NVIDIA RTX Virtual Workstation";
case NVML_BRAND_NVIDIA_CLOUD_GAMING:
  return "NVIDIA Cloud Gaming";
case NVML_BRAND_QUADRO_RTX:
  return "Quadro RTX";
case NVML_BRAND_NVIDIA_RTX:
  return "NVIDIA RTX";
case NVML_BRAND_NVIDIA:
  return "NVIDIA";
 case NVML_BRAND_GEFORCE_RTX:
  return "GeForce RTX";
case NVML_BRAND_TITAN_RTX:
  return "Titan RTX";   

I use MSVC 2022 on Windows 11. The errors occur form the console and MSVC builds.

Cheers
Helmut

Which version of CUDA do you have installed?

[hlavacs]

C:\Program Files\Microsoft Visual Studio\18\Insiders>nvcc --version
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2020 NVIDIA Corporation
Built on Mon_Oct_12_20:54:10_Pacific_Daylight_Time_2020
Cuda compilation tools, release 11.1, V11.1.105
Build cuda_11.1.relgpu_drvr455TC455_06.29190527_0

I also have 2026 installed, maybe there is a confusion.

[hlavacs]

When I start MS VS it shows 2022, but then in Help it shows Microsoft Visual Studio Community 2022 (64-bit) - Current
Version 17.14.25 (January 2026)

[mklefrancois]

All those are defined in nvml.h. My version (CUDA 12.8) contains them, I will try with the latest version (CUDA 13.1)

[mklefrancois]

I tried with the latest CUDA, there are a few deprecated functions, but it works.

Can you please try with a more recent version of CUDA?

[hlavacs]

I will after Feb 7th (no changes until then) and post here if it worked

Thanks for your efforts!
