Description Dave Malcolm 2024-12-09 18:50:46 UTC 
I'm experimentally rebuilding rawhide with the not-yet-released GCC 15 to see if anything breaks, and to help write the porting guide.

In https://download.copr.fedorainfracloud.org/results/dmalcolm/gcc-15-smoketest/fedora-rawhide-aarch64/08368364-epson-inkjet-printer-escpr/builder-live.log.gz

I see this build failure:

filter.c: In function ‘main’:
filter.c:380:15: error: too many arguments to function ‘SendStartJob’
  380 |         err = SendStartJob(FALSE);
      |               ^~~~~~~~~~~~
filter.c:49:21: note: declared here
   49 | extern EPS_ERR_CODE SendStartJob ();
      |                     ^~~~~~~~~~~~

GCC 15 defaults to C23, in which I believe the () in a decl now means "void" rather than implicit "int"; see:
https://fedoraproject.org/wiki/User:Dmalcolm/gcc-15#Function_prototypes_with_empty_params_change_from_implicit_%22int%22_to_%22void%22

Hence this looks like an issue with the prototype in filter.c

Reproducible: Always




I didn't check to see if this is fixed upstream yet.

This package has changed maintainer in Fedora. Reassigning to the new maintainer of this component.

Automation has figured out the package is retired in Fedora Rawhide.
