7# This eclass helps you find the correct wx-config script so ebuilds 5# @ECLASS: wxwidgets.eclass
8# can use gtk, gtk2 or gtk2+unicode versions of wxGTK 6# @MAINTAINER:
9 7# wxwidgets@gentoo.org
10# FUNCTIONS: 8# @BLURB: Manages build configuration for wxGTK-using packages.
11# need-wxwidgets: 9# @DESCRIPTION:
12# Arguments: 10# The wxGTK libraries come in several different possible configurations
13# 2.4: gtk gtk2 unicode 11# (release, debug, ansi, unicode, etc.) most of which can be installed
14# 2.6: gtk gtk2 gtk2-unicode base base-unicode mac mac-unicode 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# 15#
16# Ebuilds that use wxGTK _must_ inherit this eclass.
16# 17#
17# set-wxconfig 18# - Using this eclass -
18# Arguments: (wxGTK 2.4) wxgtk, wxgtk2, or wxgtk2u 19#
19# Arguments: (wxGTK 2.6) gtk-ansi gtk2-ansi gtk2-unicode base-ansi base-unicode mac-ansi mac-unicode 20# 1. set WX_GTK_VER to a valid wxGTK SLOT
20# Note: Don't call this function directly from ebuilds 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}".

91# @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.
