Hi, I've just pushed out a series of 50 patches fixing compilation warnings in a number of backends.
Most of these patches are trivial, so no ill-effects are anticipated in the general case. If your backend, or a backend you use, is the subject of one of these patches, please take a couple minutes to test it. Please, pretty please, fix warnings in your backends! It's not like the compiler complains just for the sake of complaining. Those warnings can cause real bugs on some architectures. Left over: - 1 warning in hp5400, there is a comment in the source (hp5400_internal.c) about a (correct) fix but someone needs to try it out and make sure it doesn't break calibration (no idea why it would ...) - 1 warning in niash, due to some disabled options. It'd be nice if we could find a better way to disable options than fiddling with enum values triggering compiler warnings on array bounds. - constness issues. Mostly affecting option handling code. We probably need to use a different definition inside SANE (non-const) and in the public API (const) to fix this. Other cases need some more work to fix the const poisoning that is plaguing the codebase. FWIW I've built sane-backends with both gcc and clang while fixing those warnings. I haven't actually tested the resulting binaries built with clang, though. No reason why they wouldn't work. JB. -- Julien BLACHE <http://www.jblache.org> <jb at jblache.org> GPG KeyID 0xF5D65169
