# map-opts, Qmap-opts

Maps one or more compiler options to their equivalent on a different operating system.

## Syntax

Linux: | -map-opts

macOS: | None

Windows: | /Qmap-opts

## Arguments

None

## Default

OFF | No platform mappings are performed.

## Description

This option maps one or more compiler options to their equivalent on a different operating system. The result is output to stdout.

On Windows systems, the options you provide are presumed to be Windows options, so the options that are output to stdout will be Linux equivalents.

On Linux systems, the options you provide are presumed to be Linux options, so the options that are output to stdout will be Windows equivalents.

The tool can be invoked from the compiler command line or it can be used directly.

No compilation is performed when the option mapping tool is used.

This option is useful if you have both compilers and want to convert scripts or makefiles.

### Note

Compiler options are mapped to their equivalent on the architecture you are using. For example, if you are using a processor with Intel® 64 architecture, you will only see equivalent options that are available on processors with Intel® 64 architecture.

## IDE Equivalent

None

## Alternate Options

None

## Example

The following command line invokes the option mapping tool, which maps the Linux options to Windows-based options, and then outputs the results to stdout:

    ifort -map-opts -xP -O2

The following command line invokes the option mapping tool, which maps the Windows options to Linux-based options, and then outputs the results to stdout:

    ifort /Qmap-opts /QxP /O2
