  9. # @DESCRIPTION:
  10. # This eclass sets up the proper environment for ebuilds using the wxGTK
  11. # libraries.  Ebuilds using wxPython do not need to inherit this eclass.
  12. #
  13. # More specifically, this eclass controls the configuration chosen by the
  14. # ${ESYSROOT}/usr/bin/wx-config wrapper.
  15. #
  16. # Using the eclass is simple:
  17. #
  18. #   - set WX_GTK_VER equal to a SLOT of wxGTK
  19. #   - call setup-wxwidgets()
  20. #
  21. # The configuration chosen is based on the version required and the flags
  22. # wxGTK was built with.

  53. # @FUNCTION: setup-wxwidgets
  54. # @DESCRIPTION:
  55. # Call this in your ebuild to set up the environment for wxGTK in src_configure.
  56. # Besides controlling the wx-config wrapper, this exports WX_CONFIG containing
  57. # the path to the config in case it needs to be passed to the build system.
  58. #
  59. # This function also controls the level of debugging output from the libraries.
  60. # Debugging features are enabled by default and need to be disabled at the
  61. # package level.  Because this causes many warning dialogs to pop up during
  62. # runtime, we add -DNDEBUG to CPPFLAGS to disable debugging features (unless
  63. # your ebuild has a debug USE flag and it's enabled).  If you don't like this
  64. # behavior, you can set WX_DISABLE_NDEBUG to override it.
