Tests for the presence of an --enable-config or --disable-config option. Returns true if the enable option is given, false if the disable option is given, and the default value otherwise.
This can be useful for adding custom definitions, such as debug information.
Example:
if enable_config("debug") $defs.push("-DOSSL_DEBUG") unless $defs.include? "-DOSSL_DEBUG" end
Sets a target name that the user can then use to configure various “with” options with on the command line by using that name. For example, if the target is set to “foo”, then the user could use the --with-foo-dir=prefix, --with-foo-include=dir and --with-foo-lib=dir command line options to tell where to search for header/library files.
You may pass along additional parameters to specify default values. If one is given it is taken as default prefix, and if two are given they are taken as “include” and “lib” defaults in that order.
In any case, the return value will be an array of determined “include” and “lib” directories, either of which can be nil if no corresponding command line option is given when no default value is specified.
Note that dir_config only adds to the list of places to search for libraries and include files. It does not link the libraries into your application.
Returns compile/link information about an installed library in a tuple of [cflags, ldflags, libs], by using the command found first in the following commands:
If --with-{pkg}-config={command} is given via command line option: {command} {options}
{pkg}-config {options}
pkg-config {options} {pkg}
Where options is the option name without dashes, for instance "cflags" for the --cflags flag.
The values obtained are appended to $INCFLAGS, $CFLAGS, $LDFLAGS and $libs.
If one or more options argument is given, the config command is invoked with the options and a stripped output string is returned without modifying any of the global values mentioned above.
The path to standard location of the user’s configuration directory.
The path to standard location of the user’s .gemrc file.
Returns the status of the last executed child process in the current thread.
Process.wait Process.spawn("ruby", "-e", "exit 13") Process.last_status #=> #<Process::Status: pid 4825 exit 13>
If no child process has ever been executed in the current thread, this returns nil.
Process.last_status #=> nil
Get the names of all sections in the current configuration.
Sends a OPTIONS request to the path and gets a response, as an HTTPResponse object.
Return the authoritative instance of the command manager.
Returns self. Allows a CommandManager instance to stand in for the class itself.
