alan0526 / hwinfo

cross platform C++ library for hardware information (CPU, RAM, GPU, ...)

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.

*Disks must be initialized using getAllDisks()

*Batteries should be initialized using getAllBatteries() or an ID must be provided: Battery::Battery(int8_t id)

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
   cd build
   cmake -DCMAKE_BUILD_TYPE=Release .. && make -j $(nproc)
   

Example

See example.cpp

The output should look similar to this one:

Include hwinfo in your cmake project

1. Download hwinfo into your project (e.g. in <project-root>/third_party/hwinfo)

   mkdir third_party
   cd third_party
   git clone https://github.com/lfreist/hwinfo
   

2. Simply add the following to your <project-root>/CMakeLists.txt file:

   # file: <project-root>/CMakeLists.txt
   
   add_subdirectory(third_party/hwinfo)
   include_directories(third_party/hwinfo/include)

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 hwinfo::HWinfo)
