compiling under windows 32/64 with mingw64-static ?

[stonebig]

Hi,

I would like to install (compile) gr with the mingw64 static compiler from Carl Kleffner (carlkl)
(https://bitbucket.org/carlkl/mingw-w64-for-python/downloads)

Do you think it is possible ? (I'm not expert at all in compiling outside of %cython, so I have no clue)

[jheinen]

This should be no problem. I'm currently out of office and will check that next week.

[jheinen]

FYI: I started creating makefiles for the MinGW compiler - GKS already working fine.I ask for patience ...

[stonebig]

no problem.

[stonebig]

I drop the request (with a success), as gr is now available via Christoph Gohlke.

[stonebig]

on my PC (i3-350), I have the following speed-up for http://gr-framework.org/examples/anim.html

fps (mpl): 12
fps (GR): 122
speedup: 10.2

next try is not promising:

Q: next try is not promising: http://gr-framework.org/examples/double_pendulum3.html
A: I will check this.

Q: example is not valid python 3 syntax: http://gr-framework.org/examples/figanim.html
A: Has just been fixed in the master branch.

Q: http://gr-framework.org/examples/pyqt4_ex.html gives error ...
A: The GR bdist was not built with Qt. Possible reason: missing Qt SDK or QTDIR specification.

For the impatient user - here you can download a portable Windows GR application (including Python 2.7, Qt 4.8.5, wxWidgets 2.9.4, GhostScript 9.06):

http://pgi-jcns.fz-juelich.de/pub/Downloads/gr-0.10.0-win32.zip

You simply have to change the path in gr/gr.bat, e.g.

set GRDIR=C:\gr

apparently qtplugin.dll is not shipped with Gohlke's http://www.lfd.uci.edu/~gohlke/pythonlibs/#pyqt4
I don't guess how it should comes down to my installation

figanim ok now on Python3.4 windows... printing dots

.................................................fps (mpl):    4

is creating the image but also this output on spyder internal console (not sure if it is to expect, suspect a python3+windows compatibility issue):

my system doesn't understand the exec input line in http://gr-framework.org/examples/qtgrdemo.html

    @QtCore.pyqtSlot()
    def _shellEx(self):
        input = str(self._shell.text())
        exec input
        self._shell.clear()
        self._gr.update()

`  File "D:\WinPython\basedir34\build\winpython-3.4.3.amd64\settings\.spyder2-py3\temp.py", line 224
    exec input
             ^
SyntaxError: Missing parentheses in call to 'exec'

[stonebig]

this example fails http://gr-framework.org/examples/textonaxes.html
(suspect a python 3.4 enforced rule issue)

[stonebig]

there are wheels for "gr" from Christoph Gohlke, so the original issue is droped.
I'll open separate issues for the other remarks, after redoing tests.

[stonebig]

textonaxes now works for python3.4
