Output File Extensions
The
Intel® oneAPI
produces output files with the extensions listed in the following table:

CompilerFile Name
| Description
|
|---|---|
file.i | Preprocessed file: Produced with the
-P option.
|
file.o (Linux)
file.obj (Windows)
| Object file: Produced with the
-c (Linux and Windows) object. The
/Fo (Windows) or
-o (Linux) option allows you to rename the output object file.
|
file.s (Linux)
file.asm (Windows)
