[jira] [Commented] (THRIFT-4139) warning: 'register' storage class specifier is deprecated and incompatible with C++1z [-Wdeprecated-register]

["James E. King, III (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/THRIFT-4139?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15955350#comment-15955350 ] 

James E. King, III commented on THRIFT-4139:
--------------------------------------------

This happens on clang specifically.

I'm going to add a cmake directive to squelch it as part of THRIFT-4165, where I'm upping the minimum required cmake version to 3.1 to properly support CMAKE_CXX_STANDARD.

There will be separate efforts to build successfully with {{-std=c++14}} or {{-std=c++17}} in the future.

If you want to address it separately, add this to the end of DefinePlatformSpecific.cmake:
{noformat}
if (CMAKE_CXX_COMPILER_ID MATCHES "Clang")
  set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wno-deprecated-register")
endif()
{noformat}
