编译boost程序

Question

我无法理解编译boost程序的基础知识。我正在与Fedora 15合作，通过/ usr/include/boost中的yum安装boost。我也提升了安装。

我真的很想知道如何链接boost库并在终端下编译以下示例，并使用boost-jam/build。

    using namespace std; // For atoi. 
    server s(io_service, atoi(argv[1])); 

    io_service.run(); 
    } 
    catch (std::exception& e) 
    { 
    std::cerr << "Exception: " << e.what() << "\n"; 
    } 

    return 0;

如这里要求是错误的巨块：

Answer 1

它编译罚款我g++ -lboost_system-mt -pthread。

Answer 2

看起来您可能需要在构建时明确包含boost库路径。你的确切构建命令是什么？在命令中是否有类似-L/usr/lib/boost的内容？

Answer 3

对于联Boost库的列表：

for f in $(ls -1 /usr/lib64/libboost_*.a); do basename $f .a | cut -c 4-99; done;
