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# wxwindows@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 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. Otherwise the system
17# profile will be used, meaning whatever the user happened to set it to
18# through eselect-wxwidgets.
16# 19#
17# set-wxconfig 20# Ebuilds are also required to set the variable WX_GTK_VER, containing
18# Arguments: (wxGTK 2.4) wxgtk, wxgtk2, or wxgtk2u 21# the wxGTK SLOT the ebuild requires.
19# Arguments: (wxGTK 2.6) gtk-ansi gtk2-ansi unicode base-ansi base-unicode mac-ansi mac-unicode 22#
20# Note: Don't call this function directly from ebuilds 23# Simple Usage:
24#
25# @CODE
26# WX_GTK_VER="2.8"
27#
28# inherit wxwidgets
29#
30# DEPEND="=x11-libs/wxGTK-2.8*" (or x11-libs/wxGTK:2.8 for >=EAPI 1)
31# RDEPEND="${DEPEND}"
32# [...]
33# @CODE
34#
35# In this case the eclass will use the default configuration, which is the GTK
36# libraries and either the "ansi" (in 2.6) or "unicode" (>=2.8) charsets.
37#
38# If you need more control over which profile(s) you need to use, see the
39# need-wxwidgets function below.

75# @FUNCTION: wxwidgets_pkg_setup
76# @DESCRIPTION:
77#
78# 99.99% of the time, packages building against wxGTK need the GTK libraries.
79# When using the "Simple Usage" case above (WX_GTK_VER before inherit), we have
80# to take into account that the user may have only installed the base libraries
81# (with USE="-X"). Since we can't die in global scope we instead check for
82# the presence of a base profile and then die here if found.
83#
84# If you do need to build against the wxBase libraries, you'll have to use
85# need-wxwidgets to do so.
86#
87# Note that with an EAPI 2 ebuild you can just DEPEND on x11-libs/wxGTK:2.8[X]
88# and ignore all this nonsense.

94# @FUNCTION: need-wxwidgets
95# @USAGE: <configuration>
96# @DESCRIPTION:
97#
98# need-wxwidgets is called with one argument, the wxGTK configuration to use.
99#
100# Available configurations are:
101#
102# ansi
103# unicode
104# base-ansi
105# base-unicode
106#
107# Note that in >=wxGTK-2.8, only the unicode versions are available. The
108# eclass will automatically map ansi to unicode for you if WX_GTK_VER is
109# set to 2.8 or later.
110#
111# There is one deprecated configuration, "gtk2", which is equivalent to ansi.
112# This is leftover from 2.4 when we had gtk1 and gtk2 builds and shouldn't
113# be used by new ebuilds.
114#
115# This function will export the variable WX_CONFIG, containing the absolute
116# path to the wx-config script to use. In most cases you shouldn't need to
117# use it since the /usr/bin/wx-config wrapper will already point to that
118# location when called from the eclass, but it's here if you do.
