How do you get the prop.xx file when creating a techlib in nograph mode?

jaleco

I am creating a new techlib and compiling an ascii techfile into it using the core code of ddCreateLib(), techOpenTechFile(), and tclLoadTechFile() from the attached solution.

However, I get very many warnings about the prop.xx file missing when opening the final layout in graphics mode.

The solution description says explicitly that it does not create the prop.xx file and to copy it from somewhere.

Where should the prop.xx file be copied from if it is not specific to a techlibrary? 

Since prop.xx binary, the contents are unknown, to confirm a random copy from another library is ok.

Alternatively, is there another way to create a new techlib and compile a techfile in nograph mode that would generate the prop.xx file?

    There is no need to have a prop.xx (or data.dm if OA) at the library level if you have a library with its own technology database (as is the case in this article). That article is a bit odd - I can't imagine why you'd ever copy it with a system() call. If you really wanted to copy it from another library, you really should use the ccp functions, but even then I don't see why you'd necessarily need to unless you need the specific properties.

    Without knowing what messages you're getting, I'm not sure I can advise you more...

    Regards,

    Andrew.
