   1 Installing wxPython 2.5 from Source
   2 ===================================

   5 This document will describe the few differences and additions to the
   6 content in the BUILD_ document for installing wxPython built from
   7 source.  Please follow the intstructions both in this file and in
   8 BUILD_ to perform this task.  Where there is overlap the items
   9 described here will take precedence for doing installations.

  16 Installing on Unix-like Systems (not OS X)
  17 ------------------------------------------
  18
  19 1. When building wxWidgets you need to decide if you want it to be a
  20    private copy only accessed by wxPython, or if you would like it to
  21    be installed in a stanard location such as /usr.  Or perhaps you
  22    already have a version of wxWidgets installed on your system (such
  23    as from an RPM) and you want wxPython to use that version too.  If
  24    so then you'll want to ensure that the flags and options used to
  25    build the installed version are compatible with wxPython.
  26
  27
  28 2. If you do decide to build and install your own wxWidgets then there
  29    are a few tweaks to the configure flags described in BUILD.txt that
  30    you will probably want to make.  Instead of --enable-debug use
  31    this configure flag::
  32
  33                       --enable-optimize \
  34
  35    Normally I also use the following flag in order to have wxWidgets
  36    runtime assertions turned into Python exceptions where possible.
  37    It does add extra code to the build but probably not enough to
  38    worry about it.  However if you want to get as lean a build as
  39    possible you can leave it out, but if your code does something bad
  40    then instead of exceptions you'll likely get a crash::
  41
  42                       --enable-debug_flag \
  43
  44    If you are building a private copy of wxWidgets (IOW, not installed
  45    in a standard library location) then it can be kind of a hassle to
  46    always have to set the LD_LIBRARY_PATH variable so wxPython can
  47    find the wxWidgets shared libraries.  You can hard code the library
  48    path into the binaries by using the rpath option when configuring
  49    wxWidgets.  For example::
  50
  51                      --enable-rpath=/opt/wx/2.5/lib \
  52
  53    SOLARIS NOTE: The --enable-rpath option may cause problems when
  54    using wxGTK on Solaris when compiling wxPython as described below.
  55    The woraround is to not use --enable-rpath flag for configure, but
  56    in that case all wxPython applications *must* have the
  57    LD_LIBRARY_PATH set to include $WXPREF/lib, or you can use the
  58    'crle' program to modify the runtime linking environment.  If this
  59    is the only installation of wxGTK on the system then you can use a
  60    system library path for prefix and not have to worry about it at
  61    all.
  62
  63
  64 3. Build and install wxGTK as described in BUILD.txt.
  65
  66
  67 4. In addition to building wxPython as described in BUILD.txt, you can
  68    install it to Python's site-packages dir, as well as some scripts
  69    into the same bin dir used by Python by using this command, plus
  70    whatever WXPORT, UNICODE, etc. settings you used for the initial
  71    build step::
  72
  73         python2.3 setup.py install
  74
  75    If you would like to install to some place besides the prefix where
  76    Python is installed, (such as to your home directory) then you can
  77    add "--root=<path>" after the "install" command.  This will use
  78    <path> as the prefix and will install scripts to a bin subdir and
  79    the wxPython packages to a lib subdir.  To use wxPython like this
  80    you'll need to ensure that the directory containing wxPython is
  81    contained in the PYTHONPATH environment variable.
  82
  83
  84
  85
  86 Installing on OS X
  87 ------------------
  88
  89 Installing wxPython on OS X is nearly the same as the Unix
  90 instructions above, except for a few small, but important details:
  91
  92 1. The --enable-rpath configure option is not needed since the path to
  93    the wxWidgets dylibs will automatically be encoded into the
  94    extension modules when they are built.  If you end up moving the
  95    wxWidgets dynlibs to some other location (such as inside the .app
  96    bundle of your applicaiton for distribution to other users,) then
  97    you will need to set DYLD_LIBRARY_PATH to this location so the
  98    dylibs can be found at runtime.
  99
 100 2. Depending on the version of OS X Python may be installed in
 101    different locations.  On 10.2 (Jaguar) you need to download and
 102    install MacPython-OSX-2.3 from http://www.python.org/ and the
 103    Python Framework will then be installed in /Library/Frameworks.  On
 104    10.3 (Panther) Apple supplies the Python Framework as part of the
 105    OS install, but it will be located in /System/Library/Frameworks
 106    instead.  However, on Panther the site-packages dir is sym-linked
 107    to /Library/Python/2.3 so the wxPython packages will end up there,
 108    although they will still be visible from site-packages.  If you are
 109    building distributions of wxPython to be installed on other
 110    machines be careful to install to /Library/Python/2.3.  To
 111    complicate things further, the Jaguar version, or a custom build
 112    you do yourself will end up in /Library/Frameworks even on
 113    Panther...
 114
 115 3. You need to use pythonw at the command line or the PythonLauncher
 116    app to run wxPython apps, otherwise the app will not be able to
 117    fully use the GUI display.

 122
 123 Installing on Windows
 124 ---------------------
 125
 126 1. Build wxWidgets and wxPython as described in BUILD.txt.  If you
 127    would rather have a version without the code that turns runtime
 128    assertions into Python exceptions, then use "release" instead of
 129    "hybrid" when building wxWidgets and add "FINAL=1" to the setup.py
 130    command line.
 131
 132 2. Install wxPython like this.  Remember to add any additional flags
 133    you added for the build such as UNICODE or USE_SWIG::
 134
 135       python setup.py install
 136
 137
 138 3. Copy the wxWidgets DLLs to the wx package directory so they can be
 139    found at runtime by the extension modules without requiring that
 140    they be installed on the PATH::
 141
 142         copy %WXWIN%\lib\vc_dll\wx*h_*.dll c:\Python23\Lib\site-packages\wx
