我想在我的 Mac 上使用 boost。
Mac OS X 10.7.4 Xcode 4.5
我通过自制软件安装了 boost。
brew install boost
Boost 版本是 1.49.0。我建立了我的 Xcode 项目。
添加标题搜索路径。
/usr/local/Cellar/boost/1.49.0/include
添加库
libboost * .dylib
当我编译我的项目时，我有很多错误。Clang LLVM 1.0 错误。（我想上传一张图片，但我不能上传，因为我没有超过10个声望。）
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。
带有提升“语义问题 - 未声明的标识符 va_start”的 XCode
但我找不到答案。请让我知道是否有解决方案。
使用boost的头文件是这样的。
