हाय मैं डेटा को संपीड़ित और डिकंप्रेस करने के लिए बूस्ट और ज़्लिब फ़िल्टर का उपयोग कर रहा हूं। बूस्ट पेज के निर्देश पर, यह कह रहा है यदि .cpp फ़ाइल बाहरी लाइब्रेरी पर निर्भर करती है, तो आपको इसे स्रोत से लिंक करना होगा या पूर्व-निर्मित बाइनरी से लिंक करना होगा।zlib लाइब्रेरी को कैसे लिंक करें
मैंने बूस्ट और zlib स्थापित करने के लिए मैक पोर्ट का उपयोग किया। मैं के रूप में मैं/opt बढ़ावा libarary शामिल/स्थानीय/शामिल
मेरी कोड:
#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);
}
मुझे आश्चर्य है कि पहले से बने zlib बाहरी libarary लिंक करने के लिए कैसे? यह मुझे यह संकलन समस्या दे रहा है:
