Boost矩阵在Objective C类不能编译

Boost Matrix in Objective C class does not compile

本文关键字:不能 编译 Objective Boost      更新时间:2023-10-16

我需要在我的objective/Foundation项目中使用一些boost (boost/numeric/ublas/matrix.hpp)。我使用Homebrew安装了boost(它可以在c++ Xcode项目中工作)。

我在Lion 10.7.2下使用XCode 4.2.1 (clang 3.0)。我创建了一个空的基础项目,添加了新的ObjC类,包括#include <boost/numeric/ublas/matrix.hpp>。它给了我无数的警告。

我MAMatrix

。毫米(。mm表示objc++):

#import "MAMatrix.h"
#include <boost/numeric/ublas/matrix.hpp>
@implementation MAMatrix
- (id)initWithSize:(NSUInteger)aSize
{    
    return [self initWithHeight:aSize 
                          width:aSize];
}
- (id)initWithHeight:(NSUInteger)anHeight 
               width:(NSUInteger)anWidth
{    
    self = [super init];
    if (self) {
        ;
    }
    return self;
}
@end

I am getting

template < typename Lhs, typename Rhs >
struct operator_exists {
   static ::boost::type_traits::yes_type check(has_operator); // this version is preferred when operator exists
   static ::boost::type_traits::no_type check(no_operator); // this version is used otherwise
   BOOST_STATIC_CONSTANT(bool, value = (sizeof(check(((make<Lhs>() BOOST_TT_TRAIT_OP make<Rhs>()),make<has_operator>())))==sizeof(::boost::type_traits::yes_type)));
};

我认为这可能是一个boost问题,因为STL在我的ObjC类中工作得很好。

用c-boost-1-48-type-traits-and-cocoa- inclinclude -怪诞来解决

我在foundation .h前的头文件中包含了#include <boost/numeric/ublas/matrix.hpp>
