How Can I Reliably Determine the Path of the Currently Running Executable Across Different Platforms?

Determining the Executable's Path

Obtaining the path to the currently running executable can be a challenge, especially when seeking a cross-platform solution. While previous discussions have failed to provide a universally satisfactory answer, it's worth revisiting this topic to explore potential approaches.

Platform-Specific Solutions:

• Linux: For Linux systems, you can utilize "/proc/self/exe" with std::filesystem::canonical or readlink to obtain the absolute path to the executable.
• Windows: On Windows, calling GetModuleFileName with a NULL module handle retrieves the executable's path.

Cross-Platform Limitations:

Unfortunately, there is no known cross-platform method for determining the executable's path definitively. This is due to variations in how different operating systems handle executable invocation and runtime behavior. Hence, the platform-specific solutions mentioned above offer the most reliable and widely applicable approaches.
