OVERVIEW:
2+
========
3+
4+
pythonOCC is a python library whose purpose is to provide 3D modeling features
5+
as well as parametric modeling, data exchange, meshing etc. It's intended to
6+
developers who aim at developing a complete CAD/PLM application, and to
7+
engineers who want to have a total control over the data during complex design
8+
activities.
9+
10+
ABOUT THIS DOCUMENT:
11+
====================
12+
13+
This file explains how to build pythonOCC-core from source on Windows, Linux or
14+
MacOSX platforms.
15+
16+
REQUIREMENTS:
17+
=============
18+
19+
pythonOCC needs the following libraries or programs to be installed before you
20+
can compile/use it :
21+
22+
- the python programming language (http://www.python.org). Python 2.5 or
23+
higher is required,
24+
25+
- SWIG 1.3.36 or higher,
26+
27+
- OCE 0.16 (https://github.com/tpaviot/oce),
28+
29+
- CMake 2.8 or higher (http://www.cmake.org)
30+
31+
32+
PYTHON WRAPPER COMPILATION:
33+
===========================
34+
cd to the root pythonocc directory:
35+
your_dev_folder/$cd pythonocc
36+
your_dev_folder/pythonocc$
37+
38+
Create a work directory:
39+
your_dev_folder/pythonocc$ mkdir cmake-build
40+
your_dev_folder/pythonocc$ mkdir cd cmake-build
41+
your_dev_folder/pythonocc/cmake-build$
42+
43+
Launch the cmake-gui:
44+
your_dev_folder/pythonocc/cmake-build$ cmake-gui ..
45+
46+
Check :
47+
* the oce include and lib directories,
48+
* the install path (default points to the default site-packages directory)
49+
50+
Then
51+
your_dev_folder/pythonocc/cmake-build$ make
52+
53+
When completed ([100%] done), install the python package:
54+
your_dev_folder/pythonocc/cmake-build$ make install
55+
56+
(you may have to sudo make install if admin privileges are required)
57+
58+
TEST:
59+
=====
60+
You can either run the unittest suite to check that everything is ok:
61+
your_dev_folder/pythonocc/cmake-build$ cd ../tests
62+
63+
your_dev_folder/pythonocc/src/unittests$ python run_tests.py
64+
65+
You can also run the examples avalaible from the examples directory.
