For everyone using TeXniccenter with MikTeX (pretty common combination…) here are some hints:

using the example from above, you simply have to go to your output profiles (Alt + F7), Postprocessing, New.
Type in a name, i.e. “MetaUML”, choose mpost.exe as application (located usually in your miktex distribution: miktex\bin\mpost.exe), and use %tm as argument.

This works very well for me!

Another hint:

If you are playing around you will most likely call your files test.tex or so. Don’t ever give them a name than somewhat related with the metauml package. I.e. metauml.tex or boxes.tex are very bad. These filenames (as metauml.mp an so on) exist in the metapost distribution and are included every time you “compile”. You would end up in an infinite include loop with the following error message: MetaPost capacity exceeded, sorry [text input levels=20].

So long, have fun with uml AND state charts AND use case and so on… amazing package!

can you, please, elaborate a bit on how you’ve setup MetaPost/MetaUML?

On Windows, I’ve spent a lot of time due to out-of-date state of MetaUML’s how-tos and website in general is not too informative. Finally, I ended up with TexLive installation, which somehow included the Metapost. But still, making the whole thing to work required me to install Ruby and Perl and make them both available in Path. And after all, I managed to transform website samples to PDFs. You diagram also works fine, but Use Case sample produces errors and the picture is messy in resulting PDF.

I believe that “coding” the diagrams and integrating them into intranet portals is a right way to go in software companies (I adore the idea of writing diagrams and graphs in wikis via metauml/metapost and graphviz tools). Such diagrams can be easily updated and kept within the version control in a simple way, just like the source code.

Thanks,
