Hi all,
I have developed a little GTK program which uses Matplotlib to render
plots. Now it is done, I would like to distribute for both Linux and
Windows platforms but, to make things short, I have some troubles to get
matplotlib work with GTK backend on Windows.
Basically, here is what I get when I try to use GTK backend with matplotlib:
>>> import matplotlib
>>> matplotlib.use("GTK")
>>> from pylab import *
Traceback (most recent call last):
File "<pyshell#2>", line 1, in <module>
from pylab import *
File "C:\Python26\lib\site-packages\pylab.py", line 1, in <module>
from matplotlib.pylab import *
File "C:\Python26\lib\site-packages\matplotlib\pylab.py", line 253,
in <module>
from matplotlib.pyplot import *
File "C:\Python26\lib\site-packages\matplotlib\pyplot.py", line 75,
in <module>
new_figure_manager, draw_if_interactive, show = pylab_setup()
File "C:\Python26\lib\site-packages\matplotlib\backends\__init__.py",
line 25, in pylab_setup
globals(),locals(),[backend_name])
File
"C:\Python26\lib\site-packages\matplotlib\backends\backend_gtk.py", line
25, in <module>
from matplotlib.backends.backend_gdk import RendererGDK,
FigureCanvasGDK
File
"C:\Python26\lib\site-packages\matplotlib\backends\backend_gdk.py", line
29, in <module>
from matplotlib.backends._backend_gdk import pixbuf_get_pixels_array
ImportError: No module named _backend_gdk
>>>
Here is my configuration:
Python: 2.6.2 (r262:71605, Apr 14 2009, 22:40:02) [MSC v.1500 32 bit
(Intel)] (as given by sys.version)
pygtk: 2.12.1
gtk: 2.16.1
matplotlib: 0.98.5.3 (installed using windows installer from sourceforge)
It seems to me that the matplotlib version provided was no built with
GTK support (since there is no _backend_gdk.pyd present), am I right or
did I miss something?
Based on this assumption, I tried to build matplotlib from source...
Everything went just fine until mingw tried to link this nasty
_backend_gdk.pyd.
The following command:
C:\MinGW\bin\gcc.exe -mno-cygwin -shared -s
build\temp.win32-2.6\Release\src\backend_gdk.o
build\temp.win32-2.6\Release\src\_backend_gdk.def -Lwin32_static\lib
-LC:/GTK/bin -LC:/GTK/lib -Lwin32_static\lib -LC:\Python26\libs
-LC:\Python26\PCbuild -lpython26 -lmsvcr90 -o
build\lib.win32-2.6\matplotlib\backends\_backend_gdk.pyd
actually ended in:
build\temp.win32-2.6\Release\src\backend_gdk.o:backend_gdk.c:(.text+0x18d):
undefined reference to `gdk_pixbuf_get_type'
build\temp.win32-2.6\Release\src\backend_gdk.o:backend_gdk.c:(.text+0x19f):

build\temp.win32-2.6\Release\src\backend_gdk.o:backend_gdk.c:(.text+0x232):
undefined reference to `gdk_pixbuf_get_rowstride'
collect2: ld returned 1 exit status
error: command 'gcc' failed with exit status 1
I really have no clue on this one... I must have forgotten something but
I don't get what!
Has someone got an idea?
Thanks,
Séb
