c++ - jpeg_read_image' 不是 'boost::gil' 的成员

Question

我正在尝试使用 boost::gil 读取 jpg 文件。我从以下代码片段开始，但我已经卡住了。

    #include <iostream>  
    #include <vector>
    #include <string>

    #include <boost/gil/gil_all.hpp>
    #include <boost/gil/extension/io/jpeg_dynamic_io.hpp>


     
    void ReadAnImage( std::string fname ){
                                                            
        std::vector<std::vector<float> > points;           
        boost::gil::rgb8_image_t img;                      
        boost::gil::jpeg_read_image( fname , img );               
    }                          
                               
                               
    int main( void ){
    
            ReadAnImage( "pic.jpg" );
    
    }

当我尝试用

g++ -I ~/programs/cpp/boost/include/ -std=c++11 main.cpp -o main

我收到以下错误

我不太确定我做错了什么。因为根据文档 https://www.boost.org/doc/libs/1_74_0/libs/gil/doc/html/index.html jpeg_read_image 应该包含在 boost::gil 中。我可能错过了另一个头文件吗？非常感谢任何提示。
