Manu Zhang updated MAPREDUCE-5977:
----------------------------------
Attachment: mapreduce-5977-v2.txt
Hi Sean, I've updated the patch with the following changes.
1. add compile flags "-fno-strict-aliasing" and "-Wno-sign-compare" to suppress
strict-aliasing and sign-compare warnings. all "static_cast"s have been removed;
2. "%%%c%lldlld" could be replaced with "%%%c%"PRId64""PRId64 so that PRId64
and PRIu64 work for all now;
3. as you suggest, gtest is compiled before nttest and loaded as system
library, to suppress gtest warnings. (Note that "gtest/gtest.h" is moved to
"gtest/include/gtest/gtest.h" and "gtest/include" is included as system
directory. )

> Currently, building the native task code on gcc 4.8 has a fair number of
> warnings. We should fix or suppress them so that new warnings are easier to
> see.
