In wxGTK 3.0 debugging support is always enabled in the library and it's up to packages to state if they want to use it or not. When enabled this makes warning dialogs pop up any time an assertion is encountered, which isn't very user friendly. This disables that behavior by adding -DNDEBUG to CPPFLAGS unless the package has a debug USE flag and it is enabled. Gentoo-Bug: https://bugs.gentoo.org/562480

# @BLURB: Manages build configuration for wxGTK-using packages.
|
|
# @DESCRIPTION:
|
|
# This eclass gives ebuilds the ability to build against a specific wxGTK
|
|
# SLOT and profile without interfering with the system configuration. Any
|
|
# ebuild with a x11-libs/wxGTK dependency must use this eclass.
|
|
#
|
|
# There are two ways to do it:
|
|
#
|
|
# - set WX_GTK_VER before inheriting the eclass
|
|
# - set WX_GTK_VER and call need-wxwidgets from a phase function
|
|
#
|
|
# (where WX_GTK_VER is the SLOT you want)
|
|
#
|
|
# If your package has optional support for wxGTK (ie. by a USE flag) then
|
|
# you should use need-wxwidgets. This is important because some packages
|
|
# will force-enable wxGTK if they find WX_CONFIG set in the environment.
|
|
#
|
|
# @CODE
|
|
# inherit wxwidgets
|
|
#
|
|
# IUSE="X wxwidgets"
|
|
# DEPEND="wxwidgets? ( x11-libs/wxGTK:2.8[X?] )"
|
|
#
|
|
# src_configure() {
|
|
# if use wxwidgets; then
|
|
# WX_GTK_VER="2.8"
|
|
# if use X; then
|
|
# need-wxwidgets unicode
|
|
# else
|
|
# need-wxwidgets base-unicode
|
|
# fi
|
|
# fi
|
|
# econf --with-wx-config="${WX_CONFIG}"
|
|
# }
|
|
# @CODE
|
|
#
|
|
# That's about as complicated as it gets. 99% of ebuilds can get away with:
|
|
#
|
|
# @CODE
|
|
# inherit wxwidgets
|
|
# DEPEND="wxwidgets? ( x11-libs/wxGTK:2.8[X] )
|
|
# ...
|
|
# WX_GTK_VER=2.8 need-wxwidgets unicode
|
|
# @CODE
|
|
#
|
|
# Note: unless you know your package works with wxbase (which is very
|
|
# doubtful), always depend on wxGTK[X].
|
|
#
|
|
# Debugging: In wxGTK 3.0 and later debugging support is enabled in the
|
|
# library by default and needs to be controlled at the package level.
|
|
# Use the -DNDEBUG preprocessor flag to disable debugging features.
|
|
# (Using need-wxwidgets will do this for you, see below.)
|
|

# This lets you choose which config file from /usr/lib/wx/config is used when

|
# building the package. It also exports ${WX_CONFIG} with the full path to
|
|
# that config.
|
|
#
|
|
# If your ebuild does not have a debug USE flag, or it has one and it is
|
|
# disabled, -DNDEBUG will be automatically added to CPPFLAGS. This can be
|
|
# overridden by setting WX_DISABLE_DEBUG if you want to handle it yourself.
