Bug #: 55631
Summary: Several ext/ headers can not be #included on their own
Classification: Unclassified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: ppluzhni...@google.com
The following headers:
ext/string_conversions.h
ext/alloc_traits.h
ext/pointer.h
can't be '#included' on their own (using "4.8.0 20121209"):
echo "#include <ext/string_conversions.h>" | g++ -xc++ -c -
In file included from <stdin>:1:0:
include/c++/4.8.0/ext/string_conversions.h:52:20: error: no default argument
for ‘_CharT’
_Base... __base)
^
include/c++/4.8.0/ext/string_conversions.h:52:20: error: default template
arguments may not be used in function templates without -std=c++11 or
-std=gnu++11
include/c++/4.8.0/ext/string_conversions.h:81:28: error: default template
arguments may not be used in function templates without -std=c++11 or
-std=gnu++11
const _CharT* __fmt, ...)
^
The above error should probably be fixed with:
#if __cplusplus < 201103L
# include <bits/c++0x_warning.h>
#else
(the file does compile fine in c++11 mode.)
echo "#include <ext/alloc_traits.h>" | g++ -xc++ -c - -std=c++11
In file included from include/c++/4.8.0/bits/alloc_traits.h:35:0,
from include/c++/4.8.0/ext/alloc_traits.h:35,
from <stdin>:1:
include/c++/4.8.0/bits/ptr_traits.h: In static member function ‘static _Tp*
std::pointer_traits<_Tp*>::pointer_to(typename
std::__ptrtr_not_void<_Tp>::__type&)’:
include/c++/4.8.0/bits/ptr_traits.h:174:16: error: ‘addressof’ is not a member
of ‘std’
...
Same problem as above for ext/pointer.h
