macOS:

-strict-ansi

Windows:

None

Arguments

None

Default

OFF

The compiler conforms to default standards.

Description

This option tells the compiler to implement strict ANSI conformance dialect. On Linux* systems, if you need to be compatible with gcc, use the -ansi option.

This option sets option fmath-errno, which tells the compiler to assume that the program tests errno after calls to math library functions. This restricts optimization because it causes the compiler to treat most math functions as having side effects.

IDE Equivalent

Visual Studio: None

Eclipse: Language > ANSI Conformance

Xcode: Language > C Language Dialect and Language > C++ Language Dialect

Alternate Options

None
