如何在Xcode中正确使用boost？
我尝试使用boost库编译一个项目。示例项目在终端中使用GCC 12编译得很好，但我无法让它在Xcode中编译。编译器错误主要是boost库中的命名空间问题。
例如：/boost_1_81_0/boost/compatibility/cpp_c_headers/cmath:11:11 No member named 'acos' in the global namespace .
在cmath文件中：

#ifndef __CMATH_HEADER
#define __CMATH_HEADER

#include <math.h>
namespace std {
using ::acos;
using ::cos;
using ::fmod;
using ::modf;
//...
}
#endif // CMATH_HEADER

我在OSX 12.6.1上工作，使用Xcode 14.2。包含路径设置为/usr/local/boost/boost_1_81_0。我尝试用C++20和C ++17编译。其他库包括cmath（不是来自boost）工作正常。
main.cpp中的示例项目：

#include <iostream>
#include <iterator>
#include <algorithm>

#include <boost/lambda/lambda.hpp>

int main()
{
    using namespace boost::lambda;
    typedef std::istream_iterator<int> in;
 
    std::for_each(
        in(std::cin), in(), std::cout << (_1 * 3) << " " );
}

编译器错误：
