Make sure you use the need/want_apache call # after you have defined DEPEND and RDEPEND. Also note that you can not rely on # the automatic RDEPEND=DEPEND that portage does if you use this eclass. # # See Bug 107127 for more information. # # @EXAMPLE: # # Here is a simple example of an ebuild for mod_foo: # # @CODE # APACHE2_MOD_CONF="42_mod_foo" # APACHE2_MOD_DEFINE="FOO" # need_apache2 # @CODE # # A more complicated example for a module with non-standard locations: # # @CODE # APXS2_S="${S}/apache22/src" # APACHE2_MOD_FILE="${APXS2_S}/${PN}.so" # APACHE2_MOD_CONF="42_${PN}" # APACHE2_MOD_DEFINE="FOO" # DOCFILES="docs/*.html" # need_apache2_2 # @CODE # # A basic module configuration which just loads the module into apache: # # @CODE # <IfDefine FOO> # LoadModule foo_module modules/mod_foo.so # </IfDefine> # @CODE inherit depend.apache # ============================================================================== # PUBLIC VARIABLES # ============================================================================== # @VARIABLE: APXS2_S # @DESCRIPTION: # Path to temporary build directory.
