Error: .../lib/graphviz/config is zero sized, or other read error. Error: rescanning for plugins
2. When running dot -Kxxx, you get the following output:
Layout type: "xxx" not recognized. Use one of:
Also check that HAVE_UNISTD_H is defined in config.h; for some reason, configure didn't set this on my system. Comments: [ellson]This is the first time I've encountered a PowerPC-Unix-AIX system, so you're on the bleeding edge here.
1. What is the naming convention for shared libraries on AIX? is it like: libxxxx.so.1.2.3 or something else? Perhaps you could send me the result of "ls /usr/lib/graphviz/" after you have done a "make install" ?
Does the latest graphviz-2.5.* snapshot release on http://wwww.graphviz.org/ have the same problem?
2. this is a consequence of the problem in 1.
The config check for unistd.h seems to work correctly on Linux. config.h contains
"#define HAVE_UNISTD_H 1". Where is unistd.h located on your system?
