# prof-src-root-cwd, Qprof-src-root-cwd

Lets you use relative directory paths when looking up profile data and specifies the current working directory as the base. This feature is only available for ifort.

## Syntax

Linux: | -prof-src-root-cwd

macOS: | -prof-src-root-cwd

Windows: | /Qprof-src-root-cwd

## Arguments

None

## Default

OFF | The setting of relevant options determines the path used when looking up profile data records.

## Description

This option lets you use relative directory paths when looking up profile data in .dpi files. It specifies the current working directory as the base. To use this option, you must also specify option [Q]prof-use.

This option is available during the following phases of compilation:

- Linux* and macOS systems: -prof-gen and -prof-use phases

- Windows* systems: /Qprof-gen and /Qprof-use phases

When this option is specified during the [Q]prof-gen phase, it stores information into the .dyn or .dpi file. Then, when .dyn files are merged together or the .dpi file is loaded, only the directory information below the root directory is used for forming the lookup key.

When this option is specified during the [Q]prof-use phase, it specifies a root directory that replaces the root directory specified at the [Q]prof-gen phase for forming the lookup keys.

To be effective, this option or option [Q]prof-src-root must be specified during the [Q]prof-gen phase. In addition, if one of these options is not specified, absolute paths are used in the .dpi file.
