The pkgconfig class is for packages that install <pkg>.pc files that provide information about the build settings for the package via the use of the pkg-config command. Since the contents of the file is used at build time it is required to be copied into the staging area. All the actions performed by the class are appended to the stage task. The actions performed by the pkgconfig class are: Copies the <x>.pc files into the ${PKG_CONFIG_PATH} directory; If the package is not native then it modifies the contents of the <x>.pc file in the ${PKG_CONFIG_PATH} area to ensure that all the paths in the script refer to the staging area; A package is considered to be native if it also inherits the native class. The class will search in source directory, ${S}, and all it's subdirectories, for files that end in .pc (it will ignore those that end in -uninstalled.pc) and process them as described above. All that is required to use the class is the addition of pkgconfig in an inherit statement:inherit autotools pkgconfig
