Locating Graphviz install on Windows (easy_install and/or svn install)

[ChrisWJ]

I am trying to use easy_install, but I cannot install pygraphviz
because it is complaining about not finding graphviz.
I have graphviz 2.21 vanilla Windows install (path: C:\Program Files
\Graphviz 2.21)

Then, in order to specify the library_path and include_path
explicitly, I downloaded from svn and changed setup.py values to:
library_path=C:\Program Files\Graphviz 2.21\lib
include_path=C:\Program Files\Graphviz 2.21\include
and I have tried:
include_path=C:\Program Files\Graphviz 2.21\include\graphviz

When it tries to build (using msvc), I get
pygraphviz/graphviz_wrap.c(2487) : fatal error C1083: Cannot open
include file:
'agraph.h': No such file or directory
error: command 'cl.exe' failed with exit status 2

How do I go about using pygraphviz? How can I set it up so that it
recognizes my graphviz install.

[Aric Hagberg]

The error appears to be in searching for agraph.h - one of the Graphviz
header files. Is agraph.h in :\Program Files\Graphviz 2.21\include ?

I'm don't have access to any Windows machines for testing so if
anyone has done this successfully I'd like to know. I'd be happy
to adjust the setup.py to make this easier to build.

For some reason, that file is not included in the include folder in
the Windows installation.

I would rather be on Linux right now myself, but I have no choice.

I suppose then that your installation isn't complete?
Are those files not included in the Windows installer?
If you have libagraph you might be able to get by with
just getting the few .h files you need (agraph.h and the
ones included from there).

I used cygwin and the ls command to generate a list of the files in
the installation folder. This was a default windows Graphviz install.
I shortened some sections by replacing the file contents with "..."

I think I figured it out. Graphviz dropped support for the libagraph
in the latest release (2.21). So you'll need to get 2.20 or older
and I'll have to figure out if and how I can use libcgraph instead.

Aric

[ChrisWJ]

Gotcha, thanks. I'll try again with version 2.20. Seems like that
should have been a bigger Graphviz version change than just 2.20 to
2.21. That's more like a 2.30 move; especially since it breaks the API
used to call the libraries.

I guess we were warned (I looked in the ChangeLog).
I just don't follow the graphviz development that closely.

I almost have everything working with "libgraph".
But not with version 2.21 where I get crashes with a bus error
that I haven't figured out yet. Also the subgraph handling
seems to produce different (incorrect?) results.

I'll update here when I get it all working.

[ChrisWJ]

Great thanks. Your efforts are appreciated.

I've had some success compiling the latest pygraphviz with mingw on
windows (linking and building with the latest stable version of
Graphviz), which is awesome and an improvement. Unfortunately,
whenever I go to use some of the functions, python crashes.

The simple example from here:
https://networkx.lanl.gov/trac/browser/pygraphviz/trunk//examples/simple.py
will cause a crash.

VS Debugger tells me: "Unhandled exception at 0x7c91b1fa in
python.exe: 0xC0000005: Access violation writing location 0x00000010."

By the way, way to go with compiling against the new cgraph.h.

This does work with Linux and OSX so I'm guessing either something
is miscompiled or there is a bug in the Pygraphviz interface that
shows up with mingw.

Do the basic Graphiviz functions work (e.g. dot)? Also you might try
compiling the Graphviz C example in the cgraph man page to see if that
works for you.

I am trying to see if a full cygwin with python 2.5 install will work.
Although, I am getting stuck compiling graphviz. I will report back
with status soon. I have been using the dot.exe graphviz executable
with no issues, but I will still attempt to compile and run the simple
C example as well.

[ChrisWJ]

Still trying to compile Graphviz through Cygwin because the version in
Cygwin Ports is not compiled with png output (not sure why). I keep
getting stuck with certain parts of the compilation (mostly getting
libs and configure options set right). I will further test with the
compiled Cygwin Ports version and output in other formats to make sure
they work.

If this takes much longer, I may just have to continue to output
in .dot files and call (popen()) the dot executable to produce the
output necessary.

Hi! Maybe i'm late, but for future users coming here:

I solved it by setting correctly the path of graphviz in windows (and downloading the development last snapshot):

include_dirs = 'C:/graphviz/include'

library_dirs = 'C:/graphviz/lib/release/lib'

Using / slashbars instead of windows default \

Greetings!

[23103...@qq.com]

Hi man,your answer is cool,  notice that you should use  include_dirs = 'C:/graphviz/include'  rather than 'C:/graphviz/include/graphviz'.

because the graphviz_wrap.c file uses "graphviz/cgraph.h" as its head file.

but when this problem solved, some other problems occur:
