Thuban is an interactive viewer for geographic data. |
| 9 |
Python and the wxWidgets framework ensure great portability. |
| 10 |
Thuban is Free Software and runs on GNU/Linux, Windows |
| 11 |
and several other operating systems. |

About the Name |
| 15 |
-------------- |
| 16 |
|
| 17 |
Thuban is the name of a star in the constellation Draco (The Dragon). |
| 18 |
About 4000 years ago it was the north star. |
| 19 |
|

|
| 21 |
Requirements |
| 22 |
------------ |
| 23 |
|
| 24 |
Thuban requires the following software to be installed: |
| 25 |
|
| 26 |
Python 2.2.1 http://www.python.org |
| 27 |
wxWidgets 2.4.0.4 http://www.wxwidgets.org (formerly known as wxWindows) |
| 28 |
wxPython 2.4.0.4 http://www.wxpython.org |
| 29 |
proj 4.4.5 http://www.remotesensing.org/proj/ |
| 30 |
SQLite 2.8.3 http://sqlite.org/ |
| 31 |
PySQLite 0.4.3 http://pysqlite.org/ |
| 32 |
|
| 33 |
The versions given are the lowest versions that are known to work. for |
| 34 |
proj, sqlite and pysqlite somewhat older versions probably work as well. |
| 35 |
Note that the wxPython version must be the same as the wxWidgets version |
| 36 |
(Some wxPython binary packages already contain the right wxWidgets version) |
| 37 |
|
| 38 |
Optional software: |
| 39 |
|
| 40 |
GDAL 1.2.5 http://www.remotesensing.org/gdal/ |
| 41 |
for raster image (geo-tiff) support |
| 42 |
|
| 43 |
psycopg 1.0.x http://initd.org/software/psycopg |
| 44 |
for postgis connections. Newer version probably also work |
| 45 |
|
| 46 |
|
| 47 |
Installation |
| 48 |
------------ |
| 49 |
|
| 50 |
Building Thuban (this compiles the extension modules but leaves them in |
| 51 |
a directory under build/): |
| 52 |
|
| 53 |
python setup.py build |
| 54 |
|
| 55 |
|
| 56 |
To setup Thuban to run directly from the source directory: |
| 57 |
|
| 58 |
python setup.py install_local |
| 59 |
|
| 60 |
You can run this without running build first. |
| 61 |
|
| 62 |
|
| 63 |
To install Thuban: |
| 64 |
|
| 65 |
python setup.py install |
| 66 |
|
| 67 |
|
| 68 |
for general information about the command line options of the setup.py |
| 69 |
script, run |
| 70 |
|
| 71 |
python setup.py --help |
| 72 |
|
| 73 |
|
| 74 |
If you build from CVS and want to have translated menus, dialogs etc. |
| 75 |
you have to build the message catalogs manually before you run setup.py. |
| 76 |
See po/README for more information. |
| 77 |
|
| 78 |
|
| 79 |
Build Troubleshooting |
| 80 |
--------------------- |
| 81 |
|
| 82 |
When building Thuban, you might have problems because of a missing file |
| 83 |
wx/wxPython/wxPython.h. This file is part of wxPython and may be |
| 84 |
packaged in a separate package. Unfortunately, on some systems this |
| 85 |
file is not packaged at all. On those systems you can try a work-around |
| 86 |
built into Thuban, by passing the --use-wx-python-swig-hack to the |
| 87 |
build_ext command. This can be done on the command line for the build |
| 88 |
command like this: |
| 89 |
|
| 90 |
python setup.py build_ext --use-wx-python-swig-hack build |
| 91 |
|
| 92 |
You can also use it with the install_local command: |
| 93 |
|
| 94 |
python setup.py build_ext --use-wx-python-swig-hack install_local |
| 95 |
|
| 96 |
Note, that this work-around relies on some wxPython internals and may |
| 97 |
cease to work at some point. We tested it with wxPython 2.4 and |
| 98 |
wxPython 2.5. |
