I think the error message explains itself here. The static function PRTImeToSeconds is defined but not used in this filed, which is triggering a warning which you've turned into an error.
Looking at this file, I think this is because you're compiling with --disable-accessibility, which is a non-default and non-tested option on MacOS. I strongly recommend that you compile with as few options as possible, since the defaults are what's tested and supported. --BDS On Tue, Jun 7, 2016 at 5:59 AM, matthias koplenig <mozi...@metasieben.org> wrote: > hi. > > I'm unable to build Firefox 47 with >ac_add_options > --enable-warnings-as-errors< set. 46.0.1 with this option works as > expected. > > i'm getting this error when building: > > 1:25.86 > /Volumes/data/_misc/_src/fx/release/widget/nsBaseWidget.cpp:244:1: > error: unused function 'PRTimeToSeconds' [-Werror,-Wunused-function] > 1:25.86 PRTimeToSeconds(PRTime t_usec) > 1:25.87 ^ > 1:25.87 1 error generated. > 1:25.87 > 1:25.87 In the directory > /Volumes/data/_misc/_src/fx/release/build-dir/widget > 1:25.87 The following command failed to execute properly: > 1:25.87 /usr/local/bin/ccache /usr/local/opt/ccache/libexec/clang++ -o > nsBaseWidget.o -c -fvisibility=hidden -fvisibility-inlines-hidden > -DNDEBUG=1 -DTRIMMED=1 -DMOZ_CROSS_PROCESS_IME -DOS_POSIX=1 > -DOS_MACOSX=1 -DSTATIC_EXPORTABLE_JS_API -DMOZILLA_INTERNAL_API > -DIMPL_LIBXUL -I/Volumes/data/_misc/_src/fx/release/widget > -I/Volumes/data/_misc/_src/fx/release/build-dir/widget > -I/Volumes/data/_misc/_src/fx/release/build-dir/ipc/ipdl/_ipdlheaders > -I/Volumes/data/_misc/_src/fx/release/ipc/chromium/src > -I/Volumes/data/_misc/_src/fx/release/ipc/glue > -I/Volumes/data/_misc/_src/fx/release/dom/base > -I/Volumes/data/_misc/_src/fx/release/dom/ipc > -I/Volumes/data/_misc/_src/fx/release/layout/base > -I/Volumes/data/_misc/_src/fx/release/layout/forms > -I/Volumes/data/_misc/_src/fx/release/layout/generic > -I/Volumes/data/_misc/_src/fx/release/layout/xul > -I/Volumes/data/_misc/_src/fx/release/view > -I/Volumes/data/_misc/_src/fx/release/widget > -I/Volumes/data/_misc/_src/fx/release/widget/cocoa > -I/Volumes/data/_misc/_src/fx/release/build-dir/dist/include > -I/Volumes/data/_misc/_src/fx/release/build-dir/dist/include/nspr > -I/Volumes/data/_misc/_src/fx/release/build-dir/dist/include/nss -fPIC > -DMOZILLA_CLIENT -include > /Volumes/data/_misc/_src/fx/release/build-dir/mozilla-config.h -MD -MP > -MF .deps/nsBaseWidget.o.pp -Qunused-arguments -Qunused-arguments -Wall > -Wc++11-compat -Wempty-body -Wignored-qualifiers -Woverloaded-virtual > -Wpointer-arith -Wsign-compare -Wtype-limits -Wwrite-strings > -Wc++11-compat-pedantic -Wc++14-compat -Wc++14-compat-pedantic > -Wclass-varargs -Wloop-analysis -Werror=non-literal-null-conversion > -Wthread-safety -Wunreachable-code -Wno-invalid-offsetof > -Wno-inline-new-delete -Wno-error=deprecated-declarations > -Wno-error=array-bounds -Wno-unknown-warning-option > -Wno-return-type-c-linkage -isysroot > /Users/mak/Desktop/SDKs/MacOSX10.9.sdk -fno-exceptions > -fno-strict-aliasing -fno-rtti -ffunction-sections -fdata-sections > -fno-exceptions -fno-math-errno -std=gnu++0x -pthread -DNO_X11 -pipe -g > -O3 -fomit-frame-pointer -Werror -DNO_X11 > /Volumes/data/_misc/_src/fx/release/widget/nsBaseWidget.cpp > 1:25.87 make[5]: *** [nsBaseWidget.o] Error 1 > 1:25.87 make[5]: *** Waiting for unfinished jobs.... > 1:25.89 Unified_cpp_dom_mathml0.o > > does anyone know what could be going wrong here? > > > mak. > -- > matthias koplenig - mozi...@metasieben.org > _______________________________________________ > dev-builds mailing list > dev-builds@lists.mozilla.org > https://lists.mozilla.org/listinfo/dev-builds >
