ffreestanding, Qfreestanding

Ensures that compilation takes place in a freestanding environment.

Syntax

Linux:

-ffreestanding

macOS:

-ffreestanding

Windows:

/Qfreestanding

Arguments

None

Default

OFF

Standard libraries are used during compilation.

Description

This option ensures that compilation takes place in a freestanding environment. The compiler assumes that the standard library may not exist and program startup may not necessarily be at main. This environment meets the definition of a freestanding environment as described in the C and C++ standard.

An example of an application requiring such an environment is an OS kernel.

NOTE:

When you specify this option, the compiler will not assume the presence of compiler-specific libraries. It will only generate calls that appear in the source code.

IDE Equivalent

None

Alternate Options

None
