Question

我想在Mac上使用boost。

Mac OS X 10.7.4 Xcode 4.5

我通过自制软件安装了增强功能。

brew install boost

Boost版本是1.49.0。我设置了我的Xcode项目。

添加标题搜索路径。

/usr/local/Cellar/boost/1.49.0/include

添加库

libboost * .dylib

当我编译项目时，我有很多错误。 Clang LLVM 1.0错误。（我想上传图片，但我无法上传，因为我没有超过10个声誉。）

use of undeclared identifier 'nullptr_t'; did you mean 'nullptr'?
use of undeclared identifier 'nullptr_t'; did you mean 'nullptr'?
too few template arguments for class template '__is_function'
use of undeclared identifier 'nullptr_t'; did you mean 'nullptr'?
field has incomplete type 'std::exception_ptr'
expected ';' at end of declaration list
no member named 'memcpy' in namespace 'std::__1'; did you mean 'memcpy'?
no member named 'memcpy' in namespace 'std::__1'; did you mean 'memcpy'?
expected ';' at end of declaration list
expected ';' at end of declaration list
C++ requires a type specifier for all declarations
'operator==' cannot be the name of a variable or data member
use of undeclared identifier 'nullptr_t'; did you mean 'nullptr'?
expected ';' at end of declaration
expected unqualified-id
expected ';' at end of declaration list
unknown type name 'nullptr_t'
unknown type name 'nullptr_t'
qualified reference to 'shared_ptr' is a constructor name rather than a type wherever a constructor can be declared
too many errors emitted, stopping now

我检查了这个问题。

XCode with boost "Semantic Issue - undeclared identifier va_start"

但我找不到答案。如果有解决方案，请告诉我。

使用boost的头文件是这样的。

Answer 1

您是否对标题使用递归搜索路径？如果是这样，将其更改为非递归。这可能会解决问题。

Answer 2

我有类似的问题！我解决了以下问题： Xcode-＆gt; Buid设置 - ＆gt; C ++语言Dialect（GNU ++ 11） - ＆gt; C ++标准库（libc ++（LLVM C ++ with C ++ 11）

Answer 3

我需要添加

#include <cstring>
