您好我正在使用 boost 和 zlib 过滤器来压缩和解压缩数据。在 boost 页面的说明中，如果 .cpp 文件依赖于外部库，则必须从源代码构建它或链接到预构建的二进制文件。

我使用mac端口安装boost和zlib。我将 boost 库包含为 -I/opt/local/include

我的代码：

#include <fstream>
#include <iostream>
#include <boost/iostreams/filtering_streambuf.hpp>
#include <boost/iostreams/copy.hpp>
#include <boost/iostreams/filter/zlib.hpp>

int main() 
{
    using namespace std;

    ifstream file("hello.z", ios_base::in | ios_base::binary);
    filtering_streambuf<input> in;
    in.push(zlib_decompressor());
    in.push(file);
    boost::iostreams::copy(in, cout);
}

我想知道如何链接预先构建的 zlib 外部库？它给了我这个编译问题：

mpic++ -o local ods_v2.0.cpp -I/opt/local/include

您没有编译器问题；你有一个链接问题。

添加-lboost_iostreams到命令行。您可能需要-L/opt/lib指定路径。这应该会给您另一个链接器错误，寻找zlib. 然后添加-lz.

最后一行看起来像

mpic++ -o local ods_v2.0.cpp -I/opt/local/include -L/opt/lib -lboost_iostreams -lz
