In may build I see this warning a lot:

DrawModeFlags::SettingsText | DrawModeFlags::SettingsGradient;
I’m guessing it is caused by the static in the declaration since
OUTPUT_DRAWMODE_CONTRAST seems to be used somewhere.
Compilers are free to not emit storage for that per-copilation-unit const
variable (what an oxymoron), and most compilers are apparently smart enough
to not emit a -Wunused-variable in such a case (or else the build should
break for many developers, assuming developers routinely configure
--enable-werror). Yours just isn't
I wouldn’t be able to finish any build if I turned this on, I get even
more warnings about deprecated std::auto_ptr which seems to be used in
boost’s get_pointer.hpp.
These would go away (or at least not cause an error) if you use
--without-system-boost, IIUC.
that's not the case for me. but it's odd that these warnings aren't
converted to errors with --enable-werror - they remain warnings.
Yeah, I see lots of such auto_ptr-related warnings when building with
GCC (none with Clang), but never as errors, so assumed their
non-errorness was due to the various
+# pragma GCC diagnostic ignored "-Wdeprecated-declarations"
in external/boost/boost.wdeprecated-auto_ptr.patch.0, finding no other
obvious place in the LO sources that cause them to be demoted from error
to mere warning.
---some dated GCC?
That is GCC 5.2.0, so I guess a rather too new one.
Odd, neither the Fedora 22 GCC 5.1.1 nor a recent trunk build (towards
GCC 6) triggers that warning for me when building cui.
i'm getting loads of these on Fedora 22.
"these" being auto_ptr-related warnings, or the OUTPUT_DRAWMODE_CONTRAST
-Wunused-variable that my "that warning" references?
