#134 Lots failures on FreeBSD + clang + libc++

[Anonymous]

On FreeBSD 10.0:

• In src/utils.cpp, on output << "&lt;" cannot find operator <<, missing #include <iostream></iostream>

• In private/base_cache.h, unknown type name 'time_t', missing #include <time.h>.</time.h>

• Forward declares stuff in std namespace, which is non standard, causing some code to fail compilation:

  XXX/cppcms-1.0.4/cppcms_boost/cppcms_boost/interprocess/mem_algo/detail/mem_algo_common.hpp:454:34: error: 
    implicit instantiation of undefined template 'std::pair<void *, bool>'
       std::pair<void *, bool> ret = memory_algo->priv_allocate
               ^
  XXX/cppcms-1.0.4/cppcms_boost/cppcms_boost/interprocess/interprocess_fwd.hpp:47:8: note: template
    is declared here
  struct pair;
  

  the libc++ definitions are

  _LIBCPP_BEGIN_NAMESPACE_STD
  template <class _T1, class _T2>
  struct _LIBCPP_TYPE_VIS pair { ... }
  _LIBCPP_END_NAMESPACE_STD
  

  which defines pair in an inline namespace inside namespace std. Same goes for other fwd-declarations. Replacing all of them with appropriate standard conforming includes.

• In multiple places:

  XXX/cppcms-1.0.4/cppcms_boost/cppcms_boost/interprocess/detail/managed_memory_impl.hpp:676:26: error: 
  use 'template' keyword to treat 'get_allocator' as a dependent template name
     {   return mp_header->get_allocator<T>(); }
  

• Feature detection is off: when clang is compiling in C++03 (default on my system) the CPPCMS_BOOST_NO_0X_HDR_INITIALIZER_LIST is not defined, so unordered_map.hpp introduces the functions with initializer_list arguments they fail to compile with

    no type named 'initializer_list' in namespace 'std'
  unordered_map(std::initializer_list<value_type> list,
  

  Adding -std=c++11 -stdlib=libc++ to clang command line fixed that.

I stopped here, for now.

It looks that CppCMS is not regularly tested on FreeBSD or clang, then why it is advertised as being supported on these systems?

FreeBSD builds work perfectly well with gcc/libstdc++...

Currently there are several glitches with libc++/clang even at Linux they should be solved form the nearest release.

Also some problems with libc++ still exit - with prefork cache that would be solved for 1.2 only.

Closed now it works mostly well with libc++...

There are still some glitches due to "immaturity" of libc++ but in general it looks fine
