9 # @BLURB: common ebuild functions for autotools-based packages
10 # @DESCRIPTION:
11 # autotools-utils.eclass is autotools.eclass(5) and base.eclass(5) wrapper
12 # providing all inherited features along with econf arguments as Bash array,
13 # out of source build with overridable build dir location, static archives
14 # handling, libtool files removal.
15 #
16 # Please note that autotools-utils does not support mixing of its phase
17 # functions with regular econf/emake calls. If necessary, please call
18 # autotools-utils_src_compile instead of the latter.
19 #
20 # @EXAMPLE:
21 # Typical ebuild using autotools-utils.eclass:
22 #
23 # @CODE
24 # EAPI="2"

98 # @DESCRIPTION:
99 # Set to a non-empty value in order to enable running autoreconf
100 # in src_prepare() and adding autotools dependencies.
101 #
102 # This is usually necessary when using live sources or applying patches
103 # modifying configure.ac or Makefile.am files. Note that in the latter case
104 # setting this variable is obligatory even though the eclass will work without
105 # it (to add the necessary dependencies).
106 #
107 # The eclass will try to determine the correct autotools to run including a few
108 # external tools: gettext, glib-gettext, intltool, gtk-doc, gnome-doc-prepare.
109 # If your tool is not supported, please open a bug and we'll add support for it.
110 #
111 # Note that dependencies are added for autoconf, automake and libtool only.
112 # If your package needs one of the external tools listed above, you need to add
113 # appropriate packages to DEPEND yourself.
