Question

我通过下载boost_1_67_0.tar.bz2文件并将其解压缩到以下位置来安装boost：

/cygdrive/c/no_admin_programs/boost_1_67_0

我已经在文件test.cpp中输入了以下内容：

#include <boost/lambda/lambda.hpp>
#include <iostream>
#include <iterator>
#include <algorithm>

int main()
{
    using namespace boost::lambda;
    typedef std::istream_iterator<int> in;

    std::for_each(
        in(std::cin), in(), std::cout << (_1 * 3) << " ");
}

并在终端中输入以下内容：

c++ -I /cygdrive/c/no_admin_programs/boost_1_67_0 test.cpp

As a result, the following error is shown:

我尝试将<cstdlib>包括在内都无济于事。任何帮助将不胜感激。

如果您还安装了cygwin提供的boost软件包无需尝试使用boost_1_67_0.tar.bz2

$ cygcheck -c libboost-devel
Cygwin Package Information
Package              Version        Status
libboost-devel       1.66.0-1       OK

您的程序仅能正常工作

$ c++ test.cpp

$ ./test.exe
