Plugin Troubles. Getting Started (SIP, PYQT, PYRCC confusions)Hi David,

this also may help: http://www.webalice.it/marco.pasetti/qgis+grass/BuildFromSource.html

I need to update it, but I'm too busy now.

Regards,

  Alright,

  A week of frustration solved by this blog post.  http://iwiwdsmi.blogspot.com/2007/01/how-to-install-pyqt-41-python-25-and-qt_8340.html

  The binary install worked nicely and was underneath my nose the whole time...

  Maybe someone can provide nice instruction for setting up the dev env in the wiki page. http://wiki.qgis.org/qgiswiki/PythonBindings

  This would have gotten me up and going much quicker.

  Cheers

    Hey folks, I want to create plugins for Q GIS and I am completely lost. 

    I am running python 25 on a windows box. 
    I have cygwin mingw components installed under cygwin. 
    Distutils pointing cygwin/mingw for compiling python extensions (http://boodebr.org/main/python/build-windows-extensions#CFG_DISTUTILS)

    I have been going between a bunch of sites to try and figure out how to get started. 



    The python stuff is no problem. I want to get the plugin into Qgis. 

    My understanding is that I need to comppile some resources  against pyrcc (http://wiki.qgis.org/qgiswiki/DevelopingPluginsWithPython)

    So I try finding it in the qgis install and it is not there. 

    Next I learn that pyrcc is part of the QT stack. So I go to learn how to install pyQT stuff (http://wiki.python.org/moin/PyQt)

    I go to Pyqt4 site and get the packages. I can't find binaries so I try to build form source. 

     Of course this leads me to SIP extensions, again that I need to build from source cause I can not find windows binaries.

    Am I going in the right direction or have I missed the simple approach? I like simple. 

    So now I am in cygwin trying to do 

    Python Configure.py -p cygwin-g++; make; make install 

    For the SIP package. The build fails of course. I then try PyQt, which fails cause it is missing SIP dependencies. So do I need to start with the SIP mailing list, then the Pyqt mailing list and then finaly try a small "hello world" plugin. IMHO if this is what I need to do, this is a big barrier to potential plugin developers. With applications like OpenEV I need only create a python script and run it to make a GIS plugin.

    I have not tried this on my linux box as it is proving to polute my winbox system. I like a lean linux box without all this overhead and compiling of binaries that will get hidden.



    WINDOWS BINARIES WOULD BE GREAT TO HAVE. Or maybe we just need less windows boxes... 

    In fact a QGIS plugin kit that gives you EVERYTHING would be ideal. 

    Cheers
