[BioC] problems loading the Rgraphviz package

Thu May 8 21:26:08 CEST 2008

This problem is really only for people using Graphviz on Windows using  
a binary version.

If you compile Rgraphviz (say on Linux or Mac OS X) you just install  
whatever version of graphviz you need and then compile against it.

The problem is really for Windows users using the BINARY version of  
the RGraphviz package (which most people do I think). You then need  
the exact same binary version of Graphviz as was used to create the  
RGraphviz binary version. This is apparently 2.16.

Let me iterate: the graphviz >= 12 is only really for people compiling  
from source.

Now, this is a major change from earlier where Graphviz 2.2 was  
included with the RGraphviz package for Windows users. This was great  
- no-one had to do anything to get it going. Unfortunately that  
package is beginning to get outdated and it is (for various reasons)  
very difficult to do that trick again.

So someone decided to make people install the binary version of  
Graphviz 2.16 for Windows users. I agree with Jenny that this is a  
major change and it should be kind of highlighted. The fact that she  
has missed this information is probably an indication that something  
need to be added somewhere. My guess is that this was overlooked?  
Especially since it is a very specific version of graphviz requested  
and not just any >= 2.12.
