+ The configuration section. + Consists of an arbitrary number of var elements. +

+

+ The optional platform attribute may specify a single platform identifier and + the optional not attribute may specify a comma-separated list of platform identifiers. + The configure script shall skip this config declaration if the detected platform is not matching + the filter specification of these attributes. +

+ + + + + + + + + + + + + The definition of a configuration variable. +

+ Configuration variables are supposed to be used in the configure script and are also + written to the resulting config file (in contrast to make variables, which are only + written to the config file). + The name attribute is mandatory, the value is defined by the text body of the element. + The optional Boolean exec attribute (false by default) controls, whether the entire + definition is automatically executed under command substitution. +

+ + + + + + + + + + + + + + Instructs configure to invoke pkg-config, if present on the system, to determine + compiler and linker flags. The text body of this element defines the package name to search. + To constrain the allowed versions, use the attributes atleast, exact, max. + + + + + + + + + + + + + + + Requests a compiler for the specified language. Allowed values are + c, cpp. + + + + + + + + + + + + Declares a dependency. +

+ If the optional name attribute is omitted, the dependency is global + and must be satisfied, otherwise configuration shall fail. + A named dependency can be referenced by a target (or is implicitly referenced + by the default target, if no targets are specified). + Multiple declarations for the same named dependency may exist, in which case each declaration + is checked one after another, until one block is satisfied. The result of the first satisfied + dependency declaration is supposed to be applied to the config file. +

+

+ The optional platform attribute may specify a single platform identifier and + the optional toolchain attribute may specify a single toolchain. + The optional not attribute may specify a comma-separated list of platform and/or + toolchain identifiers. + The configure script shall skip this dependency declaration if the detected platform and toolchain + is not matching the filter specification of these attributes. +

+ + + + + + + + + + + + Specifies a custom command that shall be executed to test whether this dependency is satisfied. + + + + + + + + + + + + + + + Instructs configure to append the contents of the element's body to the respective flags variable. + If the optional exec flag is set to true, the contents are supposed to be + executed under command substitution at configuration time before they are applied. + + + + + + + + + + + + + Declares a build target that is supposed to be configured. +

+ If no build target is declared explicitly, an implicit default + target is generated, which has the alldependencies + flag set. +

+

+ The optional name attribute is also used to generate a prefix + for the compiler and linker flags variables. + Furthermore, a target may consist of an arbitrary number of feature, + option, and define elements. + Named dependencies can be listed (separated by comma) in the dependencies + element. If this target shall use all available named dependencies, the empty + element alldependencies can be used as a shortcut. +

+ + + + + + + + + + + + + + + + + + Declares an optional feature, that can be enabled during configuration, if all + dependencies are satisfied. + If a feature is enabled, all define and make definitions are + supposed to be applied to the config file. + If a feature is disabled, an optional disabled element may specify which + define and make definitions are supposed to be applied. + There might also be dependencies when the feature is disabled (e.g. specifying a fallback). + In case the optional default attribute is set to true, the feature is enabled by default + and is supposed to be automatically disabled (without error) when the dependencies are not satisfied. + The name that is supposed to be used for the --enable and --disable arguments can be optionally + specified with the arg attribute.
