Subject [jira] [Commented] (HDFS-12026) libhdfs++: Fix compilation errors and warnings when compiling with Clang
Date Mon, 10 Jul 2017 19:54:07 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12026?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16080981#comment-16080981

Allen Wittenauer commented on HDFS-12026:

OK, it sounds like we're all on the same page. :)

I think adding clang to the Dockerfile is fine.  I'm not sure which compiler cmake picks up
by default, but we can add a maven test-patch profile stanza to test the "other" compiler
during CI. That's all more than reasonable and I'm really happy you folks are thinking about
it.  I'm just more concerned about the burden this may put on non-CI stuff. :)

Doing a quick search, it looks like there is only one left: hadoop-project/pom.xml if you
need an example.  That profile setting turns on java linting, FWIW.

> Currently multiple errors and warnings prevent libhdfspp from being compiled with clang.
It should compile cleanly using flags:
> -std=c++11 -stdlib=libc++
> and also warning flags:
> -Weverything -Wno-c++98-compat -Wno-missing-prototypes -Wno-c++98-compat-pedantic -Wno-padded
-Wno-covered-switch-default -Wno-missing-noreturn -Wno-unknown-pragmas -Wconversion -Werror
