Can't open Linux Schematic with Windows

[Bernd Koehler]

If I create a KiCad Schematic with Xubuntu and open this Schematic with Windows,
I get an Error on read the Symbol-ID.
The problem seems that the Symbol-ID at Linux is 16 Bytes long,
but at Windows the Symbol-ID is only 8 Bytes long.

5.0.2 is quite old already. You might consider updating to 5.1.3 and check if the error still exists.

[Michael Kavanagh (michaelkavanagh)]

As Rene said, please upgrade as the 5.0 branch is no longer maintained.

[Nick Østergaard (nickoe)]

I think there was an issue for a short while where it would save a short timestamp on 32 bit systems. I think it has been resolved on later build, but if kicad reads it I am not sure. Please test it out as mentioned.

[Ian McInerney (imcinerney)]

The timestamp issue should have been fixed in 5.1.1, see this bug report: https://bugs.launchpad.net/kicad/+bug/1821476. Changes were made to both reading and saving the schematic to fix this.

[Nick Østergaard (nickoe)]

@Ian, cool, thanj you for digging this up. :)

[Bernd Koehler (bekoger)]

We have installed Version 5.1.3 on both Systems.
On the Linux System KiCad reads the files with 16 Byte Timestamps and stores it back with 8 Byte Timestamps.
Now Windows can read the Files.

Thx a lot

Bernd
