hwinfo

hwinfo provides an easy-to-use and modern C++ API for retrieving hardware information of your systems components such as CPU, RAM, GPU, Disks, Mainboard, ...

Note

If you face any issues, find bugs or if your platform is not supported yet, do not hesitate to create an issue.

All components are available via the hwinfo::hwinfo target, or via individual CMake targets, which you can choose and link against depending on your needs.

target_link_libraries(your_target PRIVATE hwinfo::hwinfo)

or

target_link_libraries(
  your_target
  PRIVATE hwinfo::cpu
          hwinfo::gpu
          hwinfo::ram
          hwinfo::mainboard
          hwinfo::disk
          hwinfo::os
          hwinfo::battery)

The CMake options control which components will be built and available in the library:

• HWINFO_OS "Enable OS detection" (default to ON)
• HWINFO_MAINBOARD "Enable mainboard detection" (default to ON)
• HWINFO_CPU "Enable CPU detection" (default to ON)
• HWINFO_DISK "Enable disk detection" (default to ON)
• HWINFO_RAM "Enable RAM detection" (default to ON)
• HWINFO_GPU "Enable GPU detection" (default to ON)
• HWINFO_GPU_OPENCL "Enable usage of OpenCL in GPU information" (default to OFF)
• HWINFO_BATTERY "Enable battery detection" (default to ON)

Build hwinfo

Requirements: git, cmake, c++ compiler (gcc, clang, MSVC)

1. Download repository:

   git clone https://github.com/lfreist/hwinfo
   

2. Build using cmake:

   mkdir build
   cmake -B build -DCMAKE_BUILD_TYPE=Release -DCMAKE_CONFIGURATION_TYPES=Release
   cmake --build build --config Release

   This builds static and dynamic libraries. Static library cmake targets are named <target>_static (e.g. hwinfo_static)

Example

See system_infoMain.cpp

The output should look similar to this one:

include hwinfo to cmake project

Include installed version

1. Install hwinfo

   git clone https://github.com/lfreist/hwinfo && cd hwinfo
   mkdir build
   cmake -B build && cmake --build build
   cmake --install build
   

2. Simply add the following to your CMakeLists.txt file:

   # file: CMakeLists.txt
   
   find_package(hwinfo REQUIRED)

3. Include hwinfo into your .cpp/.h files:

   // file: your_executable.cpp
   
   #include <hwinfo/hwinfo.h>
   
   int main(int argc, char** argv) {
    // Your code
   }

4. Link it in cmake

   add_executable(your_executable your_executable.cpp)
   target_link_libraries(your_executable PUBLIC lfreist-hwinfo::hwinfo)

As git submodule
