こんにちは、データの圧縮と解凍にブーストと zlib フィルターを使用しています。ブースト ページの説明では、.cpp ファイルが外部ライブラリに依存している場合は、ソースからビルドするか、ビルド済みのバイナリにリンクする必要があると書かれています。

ブーストとzlibをインストールするためにMacポートを使用しました。-I/opt/local/include としてブースト ライブラリを含めます

私のコード:

#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);
}

ビルド済みの zlib 外部ライブラリをリンクする方法を教えてください。それは私にこのコンパイルの問題を与えています:

コンパイラの問題はありません。リンクの問題があります。

-lboost_iostreamsコマンドラインに追加します。-L/opt/libパスを指定する必要がある場合があります。これにより、別のリンカ エラーが発生し、zlib. 次に、追加し-lzます。

最終行は次のようになります

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