Functions Available in extconf.rb - -These functions are available in extconf.rb: - - have_macro(macro, headers, opt) - -Checks whether macro is defined with header. Returns true if the macro -is defined. - - have_library(lib, func, opt) - -Checks whether the library exists, containing the specified function. -Returns true if the library exists. - - find_library(lib, func, path...) - -Checks whether a library which contains the specified function exists in -path. Returns true if the library exists. - - have_func(func, headers, opt) - -Checks whether func exists with header. Returns true if the function -exists. To check functions in an additional library, you need to -check that library first using have_library(). -The func shall be either mere function name or function name with -arguments. -Example: - have_func("LONG2NUM(0)") - - have_var(var, header, opt) - -Checks whether var exists with header. Returns true if the variable -exists. To check variables in an additional library, you need to -check that library first using have_library(). - - have_header(header, preheaders, opt) - -Checks whether header exists. Returns true if the header file exists. - - find_header(header, path...) - -Checks whether header exists in path. Returns true if the header file -exists. - - have_struct_member(type, member, headers, opt) - -Checks whether type has member with header. Returns true if the type -is defined and has the member. - - have_type(type, headers, opt) - -Checks whether type is defined with header. Returns true if the type -is defined. - - check_sizeof(type, header) - -Checks the size of type in char with header. Returns the size if the -type is defined, otherwise nil. - - create_makefile(target) - -Generates the Makefile for the extension library. If you don't invoke -this method, the compilation will not be done. - - find_executable(bin, path) - -Finds command in path, which is File::PATH_SEPARATOR-separated list of -directories. If path is nil or omitted, environment variable PATH -will be used. Returns the path name of the command if it is found, -otherwise nil. - - with_config(withval[, default=nil]) - -Parses the command line options and returns the value specified by ---with-<withval>. - - enable_config(config, *defaults) - disable_config(config, *defaults) - -Parses the command line options for boolean. Returns true if ---enable-<config> is given, or false if --disable-<config> is given. -Otherwise, yields defaults to the given block and returns the result -if it is called with a block, or returns defaults. - - dir_config(target[, default_dir]) - dir_config(target[, default_include, default_lib]) - -Parses the command line options and adds the directories specified by ---with-<target>-dir, --with-<target>-include, and/or --with-<target>-lib -to $CFLAGS and/or $LDFLAGS. --with-<target>-dir=/path is equivalent to ---with-<target>-include=/path/include --with-<target>-lib=/path/lib. -Returns an array of the added directories ([include_dir, lib_dir]). - - pkg_config(pkg) - -Obtains the information for pkg by pkg-config command.
