Library symbol modified?

I always get the warning library symbol modified, altough update has been done. How can I find out the problem?


Highlight the symbol then run Inspect > Compare Symbol with Library

thanks for your quick reply. However I do not quite understand what the inspection wants to tell me, or in other words where does the pins differ and why they shouldn’t

something about pin 2 and 3 changed

The library symbol stacked pins 1&2, and pins 3&4. It seems you unstacked them. Or you used another (older?) version. I don’t know enough about stacked pins to say if your difference have any consequences.

the error originated because I used pin number 3 two times. After correction the warning dissappeared. It also works after stacking 1&2 and 3&4.

Interesting! No one noticed this, even though it’s a small symbol and you included a screenshot.

You should probably add a bug report on this. The DRC error message could have been much more clear on this problem.

I am very new to this forum and not very familiar yet. So I would appreciate if somebody else could write the bug report

I agree with you in general (this is a reportable bug) but this particular bug has been reported and is fixed in v9 - the message now points to the actual problem.

See Symbols containing multiple pins with same pin number produce ERC warning "Symbol 'name' has been modified in library 'libname'" (#14761) · Issues · KiCad / KiCad Source Code / kicad · GitLab and duplicates

If it’s been solved in v9, there’s no reason to report it again. Thank you!
