We spilt Qt eggs in two separated packages:

• A binary egg for users
• A development egg to deploy a development environment

Qt egg contains:

• PyQt module (*.pyd)
• Qt dll copied from Qt\bin
• QScintilla2 python module
• sip.pyd and config for sip and pyqt

All the debug dll (*4d.dll) have been removed.

from openalea.core.path import path
 
d=path('.')
for debug in d.walkfiles('*d4.dll'):
  debug.remove() 

Some other libs ended with 'd.dll' have been also removed.

Two Python files has to be modified to take into account the new paths:

• scipconfig.py (installed in site-packages)
• pyqtconfig.py (in PyQt4)

They specify configuration path which are used by sip to create Python extensions.

Qt4-dev egg contains:

• bin:
  • Qt4 bin
  • PyQt4 bin installed in Python root(pyrcc.exe, pyuic and pylupdate for instance)
• include:
  • QT4 include
  • sip include (sip build)
  • Qsci include (QScintilla/Qt4 install)
• src: QT4 src

• lib: Qt4 lib (*.a) + lib qscintilla2

Remove all debug libraries (*d4.a)

• sip:
  • PyQt4 sip
  • QScintilla sip

Note that under ubuntu, dos2unix is available within tofrodos package, which can be installed with apt-get.

# copy include and lib from QGLViewer plugin
 
# copy PyQGL lib
cp build/PyQGLViewer.so ./lib
 
wget --no-check-certificate https://gforge.inria.fr/plugins/scmsvn/viewcvs.php/*checkout*/trunk/deploy/example/setup_pyqglviewer.py?root=openalea -O setup2.py
 
python setup2.py install
python setup2.py sdist
python setup2.py bdist_egg

Prerequisite: dos2unix, patch and wget tools that can be installed using fink.

fink install dos2unix
fink install patch
fink install wget

Follow the Script under Linux with some exceptions:

• Begin directly to create the aliases
• Then get the source files
• Use the patch
• In libQGLViewer, edit QGLViewer.pro:

QGLViewer.pro is configured to generate the libraries in a library bundle. To disable this, we need to replace lib_bundle by lib in the CONFIG line.

#		--  M a c O S X  --
macx|darwin-g++ {
  # CONFIG *= lib_bundle
  CONFIG *= lib 

• Configure and build the packages
• And continue the linux procedure
