   1                       wxWidgets naming conventions
   2                       ============================
   3
   4 Being a cross platform development library, it is naturally desirable
   5 (at least to me ;) for wxWidgets to be exploited in a fully cross
   6 platform development environment -- a single invocation of make should
   7 be sufficient to build target executables for a variety of host platforms
   8 when desired.
   9
  10 Since this is now in fact possible for at least the most commonly used
  11 platforms, wxWidgets has been structured to allow multiple, simultaneous
  12 installations of the library.  Common files are shared, platform and port
  13 specific files and libraries are arranged so as to be unambiguous when
  14 installed together.
  15
  16 To manage this sanely we need a sufficiently descriptive and logical
  17 labelling convention for file and install path names -- this document (at
  18 least at its time of writing) describes the system we have adopted.
  19
  20 It is not fine grained enough to include every possible build configuration
  21 for wxWidgets, but is encompassing enough to maintain a relatively complete
  22 set of cross platform build tools on a single machine and to provide an
  23 obvious slot for new ports to slip into.
  24
  25
  26 For UNIX libraries, the canonical library name shall be of the form:
  27
  28 libwx_$(toolkit)$(widgetset)$(debug)-$(version)-$(host).$(lib_extension)
  29
  30 For MSW (native hosted only) libraries the library name should be of
  31 the form:
  32
  33 wx$(toolkit)$(widgetset)$(version)$(unicode)$(debug).$(lib_extension)
  34
  35
  36 Where:
  37
  38 --------------------------------------------------------------------
  39
  40 $toolkit must currently be one of the following:
  41
  42         msw
  43         gtk
  44         base
  45         mac
  46         os2
  47         pm
  48         mgl
  49         motif
  50
  51 --------------------------------------------------------------------
  52
  53 $widgetset may be one of:
  54
  55         univ
  56
  57 or empty if the widget set is the same as the toolkit.
  58
  59 --------------------------------------------------------------------
  60
  61 $version is a string encoding the full version (major, minor, release)
  62 for MSW, or just the major and minor number for UNIX.
  63
  64 eg. for wxWidgets 2.3.2, $version = 232 for MSW or 2.3 for UNIX.
  65
  66 The rationale for this is that under UNIX-like systems it is desirable
  67 that differently 'minor numbered' releases can be installed together,
  68 meaning your old 2.2 apps can continue to work even if you migrate
  69 development to the next stable or unstable release (eg.  2.3, 2.4),
  70 but binary compatibility is maintained between point releases (those
  71 with the same major.minor number)
  72
  73 A known break in binary compatibility should be addressed by updating
  74 the library soname (see the notes in configure.in for details on this)
  75
  76 I do not know why MSW should not also omit the release number from
  77 $version. (maybe that will change by the time this document is ratified)
  78
  79 --------------------------------------------------------------------
  80
  81 $unicode and $debug are either empty or set to 'u' and 'd'
  82 respectively when enabled.
  83
  84 --------------------------------------------------------------------
  85
  86 $host is empty for a 'native' library, (that is one where the host
  87 system is the same as the build system) or set to the value returned
  88 by the autoconf ${host_alias} variable in configure for libraries
  89 that are cross compiled.
  90
  91 --------------------------------------------------------------------
  92
  93 $lib_extension is system specific and most usually set to .a for
  94 a static library, .dll for a MSW shared library, or .so.$so_version
  95 for a shared UNIX library.
  96
  97 ====================================================================
  98
  99
 100 The installed location of the library specific setup.h is also
 101 determined by the values of these items.  On UNIX systems they
 102 will be found in:
 103
 104 $(prefix)/lib/wx/include/$(toolkit)$(widgetset)$(debug)-$(version)-$(host)/wx/
 105
 106 which will be in the include search path returned by the relevant
 107 wx-config for that library.  (or presumably set in the relevant
 108 make/project files for platforms that do not use wx-config)
 109
 110 ====================================================================
 111
 112
 113 The port specific wx-config file for each library shall be named:
 114
 115 wx-$(toolkit)$(widgetset)$(debug)-$(version)-$(host)-config
 116
 117 ${prefix}/bin/wx-config shall exist as a link to (or copy of) one of
 118 these port specific files (on platforms which support it) and as such
 119 it defines the default build configuration for wxApps on the system.
 120 It may be modified by the system user at any time.
