Don't know in which category this falls. It seems that clang treats void functions returning a value as an error while gcc only issues a warning. CLANG: scan/sane/hpaio.c:425:8: error: void function 'sane_hpaio_close' should not return a value [-Wreturn-type] return orblite_close(handle); ^ ~~~~~~~~~~~~~~~~~~~~~ scan/sane/hpaio.c:558:8: error: void function 'sane_hpaio_cancel' should not return a value [-Wreturn-type] return orblite_cancel(handle); ^ ~~~~~~~~~~~~~~~~~~~~~~ GCC: scan/sane/hpaio.c:425:15: warning: ‘return’ with a value, in function returning void 425 | return orblite_close(handle); | ^~~~~~~~~~~~~~~~~~~~~ scan/sane/hpaio.c:558:15: warning: ‘return’ with a value, in function returning void 558 | return orblite_cancel(handle); | ^~~~~~~~~~~~~~~~~~~~~~ prnt/hpps/hppsfilter.c:107:20: warning: ‘return’ with a value, in function returning void 107 | return 1; | ^
I think *somewhere* in that bunch of open upstream bugs there's a patch for compiling with clang.
(In reply to tt_1 from comment #3) > I think *somewhere* in that bunch of open upstream bugs there's a patch for > compiling with clang. Yes you are correct. Below the upstream bugs. At a first glance it seems they are addressing the issue. I will take a loo at them https://bugs.launchpad.net/hplip/+bug/1842132 https://bugs.launchpad.net/hplip/+bug/1840490
