how to link zlib library

c++ boost zlib compression

Hi I'm using boost and zlib filter to compress and decompress data. on the instruction of boost page, it is saying if the .cpp file depends on an external library, you'll have to build it from the source or link to a pre-built binary.

I used mac port to install boost and zlib. I include the boost libarary as -I/opt/local/include

my 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);
}

I wonder how to link the pre-built zlib external libarary? it is giving me this compiling problem:

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

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [local] Error 1

and how to build and link boost and zlib library on unix cluster? thanks.

You don't have a compiler problem; you have a linking problem.

Add -lboost_iostreams to the command line. You may need -L/opt/lib to specify a path. This should give you another linker error, looking for zlib. Then add -lz.

The final line will look like

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