resolve

Synopsis

qbs resolve [options] [[config:configuration-name] [property:value] ...]

Description

Resolves a project in one or more configurations. Run this command to change the properties of an existing build.

Options

--build-directory|-d <directory>

Specifies a <directory> where build artifacts are stored.

The default value is the current directory unless preferences.defaultBuildDirectory is set.

Relative paths will be interpreted relative to the current directory.

You can use the following special values as placeholders:

• @project is expanded to the name of the project file excluding the extension .qbs.
• @path is expanded to the name of the directory containing the project file.

--dry-run|-n

Performs a dry run. No commands will be executed and no permanent changes to the build graph will be done.

[--file|-f <file>]

Uses <file> as the project file. If <file> is a directory and it contains a single file with the extension .qbs, that file will be used.

If this option is not given at all, the behavior is the same as for -f <working-dir>.

--force-probe-execution

Forces re-execution of all Probe items' configure scripts, rather than using the cached data.

--less-verbose|-q

Becomes more quiet by decreasing the log level by one. This option can be given more than once. Excessive occurrences have no effect.

If the option --log-level appears anywhere on the command line in addition to this option, its value is taken as the base for the decrease.

--log-level <level>

Uses the specified log level.

Possible values of <level> are:

• error
• warning
• info (default value)
• debug
• trace

--log-time

Logs the time that the operations involved in this command take.

This option is implied in log levels debug and higher.

This option is mutually exclusive with --show-progress.

--more-verbose|-v

Becomes more verbose by increasing the log level by one. This option can be given more than once. Excessive occurrences have no effect.

If the option --log-level appears anywhere on the command line in addition to this option, its value is taken as the base for the increase.

--settings-dir <directory>

Reads all settings (such as profile information) from the specified <directory>. If the directory does not exist, it will be created.

The default value is system-specific. For example:

• Linux: $HOME/.config/QtProject/qbs
• Windows: %APPDATA%\QtProject\qbs
• macOS: $HOME/Library/Preferences/qbs

--show-progress

Shows how command execution is progressing.

This option is mutually exclusive with --log-time.

--deprecation-warnings <mode>

Uses the specified deprecation warning mode, which controls what to do when deprecated items or properties are encountered in the project. By default, a warning is emitted if the item or property is scheduled for removal in the next minor version of Qbs. Warnings can also be switched on or off unconditionally, and it can be specified that project resolving should abort if deprecated constructs are present.

Possible values of <mode> are:

• error
• on
• before-removal (default value)
• off

Parameters

config:configuration-name

Specifies the build configuration to use.

Qbs can build a project for one or multiple configurations at once, each having a different set of parameters. The config parameter has a special function: with each occurrence a new configuration instance begins and all subsequent parameters until the next config are assigned to this instance. Parameter assignments before the first occurrence of config are applied to all build configurations. Inside products and modules, the current active build configuration can be retrieved via qbs.configurationName.

In the following snippet, a profile clang is applied to all configurations while cpp.optimization is different for debug and release:

profile:clang config:debug cpp.optimization:none config:release cpp.optimization:small

The value of config determines the name of the build folder and affects the default value of the qbs.buildVariant property. Qbs knows the config values "debug" and "release", but in general any name can be chosen. When naming configurations created for special purposes, follow the rules for legal names generally used in programming languages:

• The first character must be a letter (a-z), an underscore (_), or a dollar sign ($).
• Subsequent characters may be letters, digits, underscores, or dollar signs.

property:value

Property values set in project files or profiles can be overridden on the command line. The syntax is:

<prefix>.<property-name>:<property-value>

For more information, see Overriding Property Values from the Command Line.

Examples

Resolves the default configuration of the project in the current directory:
