c++ - 在Mac上编译libzip : Undefined symbols for architecture x86_64

我一直在学习C++，因此决定尝试对文件文件(例如Word)使用libzip创建一个简单的文件阅读器。

我最近使用brew在Macbook上安装了libzip，但每次尝试编译使用libzip的程序时，我似乎总是遇到以下问题:

Undefined symbols for architecture x86_64:
  "_zip_fopen", referenced from:
      _main in main-918bfa.o
  "_zip_open", referenced from:
      _main in main-918bfa.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [a.exe] Error 1

我用来编译的命令:

g++ -g main.cpp -std=c++11 -I/usr/local/Cellar/libzip/0.11.2/include -I/usr/local/Cellar/libzip/0.11.2/lib/libzip/include -L/usr/local/Cellar/libzip/0.11.2/lib -o ../a.exe

main.cpp:

 #include <iostream>
 #include <fstream>
 #include <zip.h>
 #include <zlib.h>

 using namespace std;
 int numArgs = 2;

 int main(int argc, char** argv){
     // Parse command line arguments
     if(argc != numArgs){
         std::cout << "Incorrect number of arguments provided.\n";
         std::cout << "Command line syntax: fileReader.exe inputFile" << endl;
         exit(0);
     }

     // Try out libzip functionality
     std::string inputDocument(argv[1]);
     int err = 0;
     zip* z = zip_open(inputDocument.c_str(), 0, &err);
     if(z == NULL) {
         printf("Could not read docx file. Error code: %d", err);
         exit(-1);
     }
     zip_file* contentTypes = zip_fopen(z, "[Content_Types].xml", ZIP_FL_UNCHANGED);
     exit(0);
 }

最佳答案

看起来不像在编译命令中包含libzip库。尝试将-lzip添加到您的g++命令中
