Wie verlinke ich zlib Bibliothek

Question

Hallo Ich benutze Boost und zlib Filter um Daten zu komprimieren und zu dekomprimieren. Auf der Anweisung der Boost-Seite heißt es: Wenn die .cpp-Datei von einer externen Bibliothek abhängt, müssen Sie sie von der Quelle oder dem Link zu einer vordefinierten Binärdatei erstellen.

Ich benutzte Mac-Port, um Boost und Zlib zu installieren. Ich schließe die Boost libarary als -I/opt/local/include

meinen Code:

#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); 
} 

Ich frage mich, wie die vorgefertigte zlib externe libarary verlinken? es gibt mir dieses Compilieren Problem:

und wie zu bauen und Link-Boost und zlib-Bibliothek auf Unix-Cluster? Vielen Dank.

Answer 1

Sie haben kein Compiler-Problem; Sie haben ein Verknüpfungsproblem.

Fügen Sie -lboost_iostreams zur Befehlszeile hinzu. Möglicherweise benötigen Sie -L/opt/lib, um einen Pfad anzugeben. Dies sollte Ihnen einen weiteren Linker-Fehler geben, der nach zlib sucht. Dann fügen Sie -lz hinzu.

wird die letzte Zeile aussehen

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

Answer 2

-Boost eine ausgezeichnete Getting Started Führung hat. Schau dir das an, es sollte dir helfen, Boost zu kompilieren, zu installieren und zu verlinken.
