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

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

  14 Installing on Unix-like Systems (not OS X)
  15 ------------------------------------------
  16
  17 1. When building wxWidgets you need to decide if you want it to be a
  18    private copy only accessed by wxPython, or if you would like it to
  19    be installed in a stanard location such as /usr.  Or perhaps you
  20    already have a version of wxWidgets installed on your system (such
  21    as from an RPM) and you want wxPython to use that version too.  If
  22    so then you'll want to ensure that the flags and options used to
  23    build the installed version are compatible with wxPython.
  24
  25
  26 2. If you do decide to build and install your own wxWidgets then there
  27    are a few tweaks to the configure flags described in BUILD.txt that
  28    you will probably want to make.  Instead of --enable-debug use
  29    this configure flag::
  30
  31                       --enable-optimize \
  32
  33    Normally I also use the following flag in order to have wxWidgets
  34    runtime assertions turned into Python exceptions where possible.
  35    It does add extra code to the build but probably not enough to
  36    worry about it.  However if you want to get as lean a build as
  37    possible you can leave it out, but if your code does something bad
  38    then instead of exceptions you'll likely get a crash.
  39
  40                       --enable-debug_flag \
  41
  42    If you are building a private copy of wxWidgets (IOW, not installed
  43    in a standard library location) then it can be kind of a hassle to
  44    always have to set the LD_LIBRARY_PATH variable so wxPython can
  45    find the wxWidgets shared libraries.  You can hard code the library
  46    path into the binaries by using the rpath option when configuring
  47    wxWidgets.  For example::
  48
  49                      --enable-rpath=/opt/wx/2.5/lib \
  50
  51    SOLARIS NOTE: The --enable-rpath option may cause problems when
  52    using wxGTK on Solaris when compiling wxPython as described below.
  53    The woraround is to not use --enable-rpath flag for configure, but
  54    in that case all wxPython applications *must* have the
  55    LD_LIBRARY_PATH set to include $WXPREF/lib, or you can use the
  56    'crle' program to modify the runtime linking environment.  If this
  57    is the only installation of wxGTK on the system then you can use a
  58    system library path for prefix and not have to worry about it at
  59    all.
  60
  61
  62 3. Build and install wxGTK as described in BUILD.txt.
  63
  64
  65 4. In addition to building wxPython as described in BUILD.txt, you can
  66    install it to Python's site-packages dir, as well as some scripts
  67    into the same bin dir used by Python by using this command::
  68
  69         python2.3 setup.py install
  70
  71    If you would like to install to some place besides the prefix where
  72    Python is installed, (such as to your home directory) then you can
  73    add "--root=<path>" after the "install" command.  This will use
  74    <path> as the prefix and will install scripts to a bin subdir and
  75    the wxPython packages to a lib subdir.  To use wxPython like this
  76    you'll need to ensure that the directory containing wxPython is
  77    contained in the PYTHONPATH environment variable.

  81
  82 Installing on OS X
  83 ------------------
  84
  85 Installing wxPython on OS X is nearly the same as the Unix
  86 instructions above, except for a few small, but important details:
  87
  88 1. The --enable-rpath configure option is not needed since the path to
  89    the wxWidgets dylibs will automatically be encoded into the
  90    extension modules when they are built.  If you end up moving the
  91    wxWidgets dynlibs to some other location (such as inside the .app
  92    bundle of your applicaiton for distribution to other users,) then
  93    you will need to set DYLD_LIBRARY_PATH to this location so the
  94    dylibs can be found at runtime.
  95
  96 2. Depending on the version of OS X Python may be installed in
  97    different locations.  On 10.2 (Jaguar) you need to download and
  98    install MacPython-OSX-2.3 from http://www.python.org/ and the
  99    Python Framework will then be installed in /Library/Frameworks.  On
 100    10.3 (Panther) Apple supplies the Python Framework as part of the
 101    OS install, but it will be located in /System/Library/Frameworks
 102    instead.  However, on Panther the site-pacakges dir is sym-linked
 103    to /Library/Python/2.3 so the wxPython pacakges will end up there,
 104    although they will still be visible from site-packages.  If you are
 105    building distributions of wxPython to be installed on other
 106    machines be careful to install to /Library/Python/2.3.  To
 107    complicate things further, the Jaguar version, or a custom build
 108    you do yourself will end up in /Library/Frameworks even on
 109    Panther...
 110
 111 3. You need to use pythonw at the command line or PythonLauncher app
 112    to run wxPython apps, otherwise the app will not be able to fully
 113    use the GUI display.

 119 Installing on Windows
 120 ---------------------
 121
 122 1. Build wxWidgets and wxPython as described in BUILD.txt.  If you
 123    would rather have a version without the code that turns runtime
 124    assertions into Python exceptions, then use "release" instead of
 125    "hybrid" when building wxWidgets and add "FINAL=1" to the setup.py
 126    command line.
 127
 128 2. Install wxPython like this::
 129
 130       python setup.py install
 131
 132
 133 3. Copy the wxWidgets DLLs to the wx package directory so they can be
 134    found at runtime by the extension modules without requiring that
 135    they be installed on the PATH::
 136
 137         copy %WXWIN%\BIN\wx*h_*.dll c:\Python23\Lib\site-pacakges\wx
