[Comment 1 Patrick Lauer 2013-04-08 08:31:45 UTC]

Technically speaking this is not a gcc 4.8 error but a -Werror "problem" in the makefile

[Comment 2 Yixun Lan 2013-07-25 06:54:33 UTC]

Created attachment 354146 [details, diff]
backport patch from version 1.10, fix the compile error

there is already a patch for version mozc-1.10.1390.102 which remove the "-Werror" compile flag, backport to 1.6 fix this problem.

attached file is the ebuild patch

[Comment 3 Julian Ospald 2013-07-25 10:11:04 UTC]

Specific -Werror=* flags are NOT disregarded by QA, unless we know that the warning is stupid in this case.

[Comment 4 Naohiro Aota 2013-07-28 10:33:33 UTC]

Really need this for 1.6? Both 1.6 and 1.10 is testing. I'm considering to drop older versions. They also have problem with python eclass.

No, any use of -Werror is not allowed.  Drop it please.
