NAME

wxwidgets.eclass - 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.

     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}"
     }

That's about as complicated as it gets. 99% of ebuilds can get away with:

     inherit wxwidgets
     DEPEND="wxwidgets? ( x11-libs/wxGTK:2.8[X] )
     ...
     WX_GTK_VER=2.8 need-wxwidgets unicode

Note: unless you know your package works with wxbase (which is very doubtful), always depend on wxGTK[X].

FUNCTIONS

need-wxwidgets <profile>

Available configurations are:

unicode (USE="X")
base-unicode (USE="-X")
