# @BLURB: convenient wrapper to build autotools packages out-of-source
|
|
# @DESCRIPTION:
|
|
# This eclass provides a minimalistic wrapper interface to easily
|
|
# build autotools (and alike) packages out-of-source. It is meant
|
|
# to resemble the interface used by multilib-minimal without actually
|
|
# requiring the package to be multilib.
|
|
#
|
|
# For the simplest ebuilds, it is enough to inherit the eclass
|
|
# and the new phase functions will automatically build the package
|
|
# out-of-source. If you need to redefine one of the default phases
|
|
# src_configure() through src_install(), you need to define
|
|
# the matching sub-phases: my_src_configure(), my_src_compile(),
|
|
# my_src_test() and/or my_src_install(). Those sub-phase functions
|
|
# will be run inside the build directory. Additionally,
|
|
# my_src_install_all() is provided to perform doc-install and other
|
|
# common tasks that are done in source directory.
|
|
#
|
|
# Example use:
|
|
# @CODE
|
|
# inherit out-of-source
|
|
#
|
|
# my_src_configure() {
|
|
# econf \
|
|
# --disable-static
|
|
# }
|
|
# @CODE
