Dear John
Thanks for the reply.
Please note the following points.
1. I have been able to build the source code from trunk and presently writing
some simple models from the area of electronics.
2. Regarding graphviz i have updated the graphviz.py on my system and it is
working fine. I have added a try/except block to consider both libagraph(for
older version) and libcgraph(for newer version). I have checked graph.c and all
the struct types and functions used are working fine.
Also attaching the patch file below.
3. Also working on making the Graphviz allowable runtime(dlopen) dependency. It
seems the graph.c and graph.h will need some editing. Please add any comments.
Regards,
Divyanshu

Hi Divyanshu
Thanks for your helpful feedback. I have added further comments below.

IPOPT latest release is needed; unfortunately the version in Ubuntu
doesn't
work properly
http://ascendwiki.cheme.cmu.edu/IPOPT
I have updated the 'Building ASCEND' page accordingly, thanks for
pointing this out.

Graphviz has been updated in Ubuntu 10.10 and now provides a different
API. We would like to fix this by (a) changing the core ASCEND code so
that Graphviz is not directly linked to ASCEND but instead is an
allowable runtime (dlopen) dependency, and (b) update the bit of code
that links against Graphviz so that it can use both older and newer
versions of Graphviz. Would you perhaps like to work on that issue? It
would certainly be very helpful, and a relatively small, self-contained
task for you to start with.
If not, you may need to try to get hold of an
older graphviz
package for
your system -- try manually downloading the relevant packages for Ubuntu
10.04 instead, and installing them using 'dpkg'.
The relevant bug in our bug tracker is
http://ascendbugs.cheme.cmu.edu/view.php?id=443, and I have also updated
the wiki.
Cheers
JP
