GDS open issue

Rakesh

Hi, I am trying out the macros, starting with the sample code listed on the website. I face an error showing the unable to open the .gds file (errno: 13). I made sure that the code file is in the same path. But not sure, why the error is?

Thanks,
-Rakesh.

Is there a listing of all the klayout errors that could be thrown,
with probable causes, anywhere in the docs-pile?

I didn't find anything in the Assistant, but I can't call that a
surprise. No search hits in the online manual either.

If not, it would make a nice Appendix....

Did you read the error message? Where is KLayout supposed to store the file? The notation you used means (in unix and I think even POSIX) use the current folder, which under windows would (most likely) be C:\Program Files\KLayout\t.gds if even supported and looking at the source code it's not the case for Windows (could be mistaken when glancing over it though), which as you can guess is a bad idea and would require administrator rights. You should add a path, e.g. C:\Users\Rakesh\Documents\t.gds and then it should work

@dick_freebird sure there is https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/errno.h.html these are the standard POSIX errors which is exactly what KLayout is throwing (in this case and others where standard errors apply)

you can get the error with for example python

import errno
errno.errorcode.get(13)

But I mean in this case it is a bit useless to do that as the error message already tells you what is wrong.
