# @BLURB: Provides common ebuild phases for oasis-based packages.
|
| 11 |
# @DESCRIPTION:
|
| 12 |
# Provides common ebuild phases for oasis-based packages.
|
| 13 |
# Most of these packages will just have to inherit the eclass, set their
|
| 14 |
# dependencies and the DOCS variable for base.eclass to install it and be done.
|
| 15 |
#
|
| 16 |
# It inherits multilib, findlib, eutils and base eclasses.
|
| 17 |
# Ebuilds using oasis.eclass must be EAPI>=3.
|
| 18 |
|
| 19 |
# @ECLASS-VARIABLE: OASIS_BUILD_DOCS
|
| 20 |
# @DESCRIPTION:
|
| 21 |
# Will make oasis_src_compile build the documentation if this variable is
|
| 22 |
# defined and the doc useflag is enabled.
|
| 23 |
# The eclass takes care of setting doc in IUSE but the ebuild should take care
|
| 24 |
# of the extra dependencies it may need.
|
| 25 |
# Set before inheriting the eclass.
|
| 26 |
|
| 27 |
# @ECLASS-VARIABLE: OASIS_BUILD_TESTS
|
| 28 |
# @DESCRIPTION:
|
| 29 |
# Will make oasis_src_configure enable building the tests if the test useflag is
|
| 30 |
# enabled. oasis_src_test will then run them.
|
| 31 |
# Note that you sometimes need to enable this for src_test to be useful,
|
| 32 |
# sometimes not. It has to be enabled on a per-case basis.
|
| 33 |
# The eclass takes care of setting test in IUSE but the ebuild should take care
|
| 34 |
# of the extra dependencies it may need.
|
| 35 |
# Set before inheriting the eclass.
|
| 36 |
|
| 37 |
|
| 38 |
# @ECLASS-VARIABLE: OASIS_NO_DEBUG
|
| 39 |
# @DESCRIPTION:
|
| 40 |
# Disable debug useflag usage. Old oasis versions did not support it so we allow
|
| 41 |
# disabling it in those cases.
|
| 42 |
# The eclass takes care of setting debug in IUSE.
|
| 43 |
# Set before inheriting the eclass.
