jak połączyć bibliotekę zlib

Question

Witam Używam filtra boost i zlib do kompresowania i dekompresji danych. zgodnie z instrukcją strony doładowania mówi się: , jeśli plik .cpp zależy od biblioteki zewnętrznej, będziesz musiał zbudować ją ze źródła lub łącza do gotowego pliku binarnego.

Użyłem portu mac do zainstalowania boost i zlib. I obejmują libarary doładowania jak -I/opt/local/include

mój kod:

#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); 
} 

Zastanawiam się, jak połączyć wstępnie zbudowane zlib zewnętrznego libarary? daje mi to kompilujący się problem:

oraz jak zbudować i połączyć bibliotekę boost i zlib w klastrze unix? dzięki.

Answer 1

Nie masz problemu z kompilatorem; masz problem z linkowaniem.

Dodaj -lboost_iostreams do linii poleceń. Aby podać ścieżkę, możesz potrzebować -L/opt/lib. To powinno dać ci inny błąd łącznika, szukając zlib. Następnie dodaj -lz.

Końcowa linia będzie wyglądać

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

Answer 2

doładowania ma doskonałą Getting Started przewodnika. Spójrz, to powinno pomóc Ci skompilować, zainstalować i połączyć z Boost.
