646776 - compile errors caused by -Werror and current gcc versions

Status: RESOLVED FIXED

(Core :: JavaScript Engine, defect)

Description

[Wolfgang Rosenauer [:wolfiR]]

cc1plus: warnings being treated as errors
/usr/src/packages/BUILD/mozilla/js/src/shell/js.cpp: In function 'void my_ErrorReporter(JSContext*, const char*, JSErrorReport*)':
/usr/src/packages/BUILD/mozilla/js/src/shell/js.cpp:5320:53: error: ignoring return value of 'size_t fwrite(const void*, size_t, size_t, FILE*)', declared with attribute warn_unused_result
/usr/src/packages/BUILD/mozilla/js/src/nanojit/Nativei386.h: At global scope:
/usr/src/packages/BUILD/mozilla/js/src/nanojit/Nativei386.h:167:31: error: 'nanojit::ScratchRegs' defined but not used
/usr/src/packages/BUILD/mozilla/js/src/nanojit/Nativei386.h:170:31: error: 'nanojit::AllowableByteRegs' defined but not used

-Werror is also used in mozilla.org's Linux builds but gcc 4.3.3 seems to not complain about those. At least gcc 4.5 and above does.

The warnings-as-errors in bug 609532 has been turned off, which should fix this problem.
