## Special considerations for Linux/macOS

Debugging symbols (data about your program required for debugging) is by default part of native executable files on Unix-like operating systems. To minimize the size of your native executable, you can run the `strip` tool to remove the debugging symbols.
Debugging symbols (data about your program required for debugging) is by default part of native executable files on Unix-like operating systems. To strip symbols into a separate file (`*.dbg` on Linux and `*.dwarf` on macOS), set `<StripSymbols>true</StripSymbols>`.

No action is needed on Windows since the platform convention is to generate debug information into a separate file (`*.pdb`).

Debugging symbols (data about your program required for debugging) is by default part of native executable files on Unix-like operating systems. To strip symbols into a separate file (`*.dbg` on Linux and `*.dwarf` on macOS), set `<StripSymbols>true</StripSymbols>`.

No action is needed on Windows since the platform convention is to generate debug information into a separate file (`*.pdb`).

## Special considerations for Linux/macOS

Debugging symbols (data about your program required for debugging) is by default part of native executable files on Unix-like operating systems. To minimize the size of your native executable, you can run the `strip` tool to remove the debugging symbols.
Debugging symbols (data about your program required for debugging) is by default part of native executable files on Unix-like operating systems. To strip symbols into a separate file (`*.dbg` on Linux and `*.dwarf` on macOS), set `<StripSymbols>true</StripSymbols>`.

No action is needed on Windows since the platform convention is to generate debug information into a separate file (`*.pdb`).
