How Can I Reliably Retrieve the Executable Path Across Different Platforms?

Cross-Platform Retrieval of Executable Path

Achieving platform-independent retrieval of the executable path has proven elusive in the past. Despite previous inquiries, a definitive solution or a clear "impossible" verdict has not yet been reached.

Platform-Specific Solutions

While a universal solution remains elusive, platform-specific approaches exist:

• Linux: Use "/proc/self/exe" as input to std::filesystem::canonical or readlink functions.
• Windows: Pass NULL as the module handle parameter to GetModuleFileName.

Ogre and Very Sleepy:

In the specific case of an Ogre game being profiled by Very Sleepy, the absolute path to configuration files can be passed to Very Sleepy. This ensures the game can locate the files regardless of the working directory.

Visual Studio Debugging:

To run executables without setting the working directory in Visual Studio, use $(TargetPath) and pass NULL to GetModuleFileName.

Additional Notes:

Other approaches may work on specific systems but may not be portable. It is advisable to thoroughly test any solution before relying on it in production environments.
