# @BLURB: Manages build configuration for wxGTK-using packages. |
| 9 |
# @DESCRIPTION: |
| 10 |
# The wxGTK libraries come in several different possible configurations |
| 11 |
# (release, debug, ansi, unicode, etc.) most of which can be installed |
| 12 |
# side-by-side. The purpose of this eclass is to provide ebuilds the ability |
| 13 |
# to build against a specific type of profile without interfering with the |
| 14 |
# user-set system configuration. |
| 15 |
# |
| 16 |
# Ebuilds that use wxGTK _must_ inherit this eclass. |
| 17 |
# |
| 18 |
# - Using this eclass - |
| 19 |
# |
| 20 |
# 1. set WX_GTK_VER to a valid wxGTK SLOT |
| 21 |
# 2. inherit wxwidgets |
| 22 |
# 3. add an appropriate DEPEND |
| 23 |
# 4. done |
| 24 |
# |
| 25 |
# @CODE |
| 26 |
# WX_GTK_VER="2.8" |
| 27 |
# |
| 28 |
# inherit wxwidgets |
| 29 |
# |
| 30 |
# DEPEND="x11-libs/wxGTK:2.8[X]" |
| 31 |
# RDEPEND="${DEPEND}" |
| 32 |
# [...] |
| 33 |
# @CODE |
| 34 |
# |
| 35 |
# This will get you the default configuration, which is what you want 99% |
| 36 |
# of the time (in 2.6 the default is "ansi", all other versions default to |
| 37 |
# "unicode"). |
| 38 |
# |
| 39 |
# If your package has optional wxGTK support controlled by a USE flag or you |
| 40 |
# need to use the wxBase libraries (USE="-X") then you should not set |
| 41 |
# WX_GTK_VER before inherit and instead refer to the need-wxwidgets function |
| 42 |
# below. |
| 43 |
# |
| 44 |
# The variable WX_CONFIG is exported, containing the absolute path to the |
| 45 |
# wx-config file to use. Most configure scripts use this path if it's set in |
| 46 |
# the environment or accept --with-wx-config="${WX_CONFIG}". |

# @FUNCTION: wxwidgets_pkg_setup |

# @DESCRIPTION: |
| 92 |
# |
| 93 |
# It's possible for wxGTK to be installed with USE="-X", resulting in something |
| 94 |
# called wxBase. There's only ever been a couple packages in the tree that use |
| 95 |
# wxBase so this is probably not what you want. Whenever possible, use EAPI 2 |
| 96 |
# USE dependencies(tm) to ensure that wxGTK was built with USE="X". This |
| 97 |
# function is only exported for EAPI 0 or 1 and catches any remaining cases. |
| 98 |
# |
| 99 |
# If you do use wxBase, don't set WX_GTK_VER before inherit. Use |
| 100 |
# need-wxwidgets() instead. |
