Subject: cups failing with "undefined symbol __stdin / __stdout"
To: ports@openbsd.org, misc@openbsd.org
Date: Sun, 23 Aug 2026 09:59:03 +0100

Hello All,

Cups (2.4.19) seems to be failing on my end on -current. I get the
below error log when trying to print _anything_ (test pages, documents,
etc).

The admin panel sayts that "pdftopdf" failed:

```
"cfFilterChain: pdftopdf (PID 10186) stopped with status 1"
```

The only thing I can see in /var/logs/cups/error_log that seems to
stand out for me is the repeating error message for various libraries,
complaining that there are no symbols for __stdin and __stdout.

I am on the latest snapshot:

kern.version=OpenBSD 8.0-beta (GENERIC.MP) #108: Sat Aug 22 22:10:43
MDT 2026
    deraadt@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP


Any advice?

Thanks

rqm
