# Save Compiler Information in Your Executable

If you want to save information about the compiler in your executable, use the [Q]sox option to save:

- Compiler version number and options used to produce the executable.
- Profile data and inlining information (if optional arguments were specified).

## Linux

To view the information stored in the object file, use the `objdump` command. For example:

    objdump -sj comment a.out
    strings -a a.out | grep comment:

## Windows

To view the linker directives stored in string format in the object file, use the `link` command. For example:

    link /dump /directives filename.obj

In the output, the ?-comment linker directive displays the compiler version information. To search your executable for compiler information, use the `findstr` command. For example, to search for any strings that contain the substring "Compiler":

    findstr "Compiler" filename.exe
