Just another MoinMoin convert...
I found the Gdchart graphics very nice, but there were no real good instructions to install the product. I don't pretend this is the best doc you have ever seen, but it worked for me. This is why I created this page...

GDchart support for MoinMoin
Required to display graphs in the EventStats/UserAgents and EventStats/HitCounts and all pages info. The following worked on a Linux Gentoo system, the directories locations will vary with other Linux distros.
Download pygdchart-0.6.1.tar.gz, to be found at GD Python interface
Untar the file, then go it's pygdchart-0.6.1/gd-1.8.4 directory.
Compile gdchart by running the command "make".
copy the following files from pygdchart-0.6.1/gd-1.8.4/ to /usr/lib:
gd.o gd_gd.o gd_gd2.o gd_io.o gd_io_dp.o gd_io_file.o gd_io_ss.o gd_jpeg.o gd_png.o gd_ss.o gd_wbmp.o gdcache.o gdfontg.o gdfontl.o gdfontmb.o gdfonts.o gdfontt.o gdft.o gdhelpers.o gdkanji.o gdtables.o gdttf.o gdxpm.o wbmp.o
Go to pygdchart-0.6.1 directory and edit the file "Makefile". For Gentoo, I had to change the following:
HAVE_JPEG = 0 PY_INCLUDE = -I/usr/include/python2.2/
Then run the command "make"
Copy the file gdchart.so to /usr/lib/python2.2
To test if it is working, launch Python and try: "import gdchart"
The following two ebuilds install the latest versions of GDChart and PyGDChart, but it appears that MoinMoin 1.1 can't use them.

commentary:
windows binaries here (for python 2.2)
or better look here
Here's a windows binary that fritzm built for Python 2.5: gdchart25.pyd. Rename it to gdchart.pyd and drop it in your Python25\DLLs dir.
chart.py gdchart.pyd test.py w.gif
just copy the file gdchart.pyd to your directory Python22\DLLs.
-- added 2002-08-08 16:25:34 by bootlab
But where does the chart.py file get copied? I tried the Python\lib directory without any luck. -- BernardFarrell 2026-01-11 12:27:20
Redhat 7.x users: Here is my install notes:
- Read the README file in the pygdchart source tar package.
Edit the Makefile, make sure the PY_INCLUDE is the correct directory where your python2.x head file is installed, mine is:
HAVE_JPEG = 1 PY_INCLUDE = -I/usr/local/include/python2.2 LIB_DIRS = -L/usr/local/lib -L/usr/lib GCC = gcc CFLAGS = -Wall -fpic -O2
- type "make" to build gdchart.so and copy to a directory in your $PYTHONPATH, I copyed it to /moin/lib/python2.2/site-packages/
That's all ---
Problems Installing PyGDChart on OpenBSD
Hi I�m very happy bout my first WikiWiki (oops, MoinMoin 
) Installation (running 1.11 cvs tarball), but I just CAN�T install this module
I get this error when I want to compile stuff
# cd pygdchart-0.6.1 # make "Makefile", line 50: Missing dependency operator "Makefile", line 53: Need an operator Fatal errors encountered -- cannot continue
Lines in Makefile are these:
49 ifeq ($(HAVE_JPEG),1) 50 DEFS += -DHAVE_JPEG 51 LIBJPEG = -ljpeg 52 endif 53
Can someone plz help?
- Use gmake.
- You mean GNU make?
- Yes.
Better yet, make a port and submit it to OpenBSD
- You mean GNU make?
