Subject: Minimum requirements for gcc in order to compile c-ares?
Message-ID: <SJ0PR04MB8289A6A6AF24AC656CEE060A9CFF9@SJ0PR04MB8289.namprd04.prod.outlook.com>

Hello,

I'm trying to compile c-ares on a RHEL7 server with gcc/g++ v4.8.5 .  My compilation is failing with many errors, the first of which is as follows:

In file included from ares-test.h:12:0,
                 from ares-test-main.cc:4:
./gmock-1.11.0/gtest/gtest.h: In static member function 'static constexpr bool testing::internal::MatcherBase<T>::IsInlined()':
./gmock-1.11.0/gtest/gtest.h:6495:12: error: 'is_trivially_copy_constructible' is not a member of 'std'

Based on a Google search, I infer that my gcc version is too old.  What are the minimum requirements to compile c-ares?

Thank you and regards,

You just need to disable the test cases.? The test cases require a C++11 
or higher compiler.? c-ares itself will build fine with any c89 compiler.

If you're using the autotools configure script, just pass 
--disable-tests? if you're using CMake, you would pass 
-DCARES_BUILD_TESTS=OFF

You just need to disable the test cases.  The test cases require a C++11 or higher compiler.  c-ares itself will build fine with any c89 compiler.

[Mun] Thank you very much for your quick and informative response!  The use of --disable-tests did the trick.

Best regards,

Subject: [RELEASE] c-ares 1.19.0
Message-ID: <70s580n7-ss4-3os7-8rpo-57pq742117rr@unkk.fr>

Hi friends.

c-ares 1.19.0 was just packaged and uploaded. Available as always from:

   https://c-ares.org/

c-ares version 1.19.0

This is a feature and bugfix release.  It addresses a couple of new feature
requests as well as a couple of bug fixes.

Security:
  o Low. Stack overflow in ares_set_sortlist() which is used during c-ares
    initialization and typically provided by an administrator and not an
    end user. [24]

Changes:
  o Windows: Drop support for XP and derivatives which greatly cleans up
    initialization code. [3]
  o Add ARES_OPT_HOSTS_FILE similar to ARES_OPT_RESOLVCONF for specifying a
    custom hosts file location. [10]
  o Add vcpkg installation instructions [13]

Bug fixes:
  o Fix cross-compilation from Windows to Linux due to CPACK logic. [1]
  o Fix memory leak in reading /etc/hosts when using localhost fallback. [2]
  o Fix chain building c-ares when libresolv is already included by another
    project [4]
  o File lookup should not immediately abort as there may be other tries due to
    search criteria.
  o Asterisks should be allowed in host validation as CNAMEs may reference
    wildcard domains [5]
  o AutoTools build system referenced bad STDC_HEADERS macro [6]
  o Even if one address class returns a failure for ares_getaddrinfo() we 
should
    still return the results we have
  o CMake Windows: DLLs did not include resource file to include versions [7] 
[8]
  o CMake: Guard target creation in exported config [9]
  o Fix ares_getaddrinfo() numerical address resolution with AF_UNSPEC [11]
  o Apple: fix libresolv configured query times. [12]
  o Fix tools and help information [14] [15]
  o Various documentation fixes and cleanups [16] [22] [25]
  o Add include guards to ares_data.h [17]
  o c-ares could try to exceed maximum number of iovec entries supported by
    system [18]
  o CMake package config generation allow for absolute install paths [19]
  o Intel compiler fixes [20]
  o ares_strsplit bugs [21] [23]
  o The RFC6761 6.3 states localhost subdomains must be offline too. [26]
