我是 C++ 新手，最近参加了一门课程向我介绍该语言，因此我了解了语法的基础知识，但没有讨论如何使用外部库并将它们连接到我们的代码。
我正在尝试使用 CLP COIN 库从...解决线性程序 http://www.coin-or.org/Clp/userguide/clpuserguide.html#id4766717
从我在那里读到的内容，它建议使用预编译的二进制库而不是下载源代码，因为我在 Windows 7 平台上，因为他们建议在 Windows 上重新编译有时会引入问题。
我只是想让相当于 Hello World 的工作。这是他们提供的用于测试的示例代码......

/* This shows how to provide a simple picture of a matrix.
The default matrix will print Hello World
*/
#include "ClpSimplex.hpp"
int main (int argc, const char *argv[])
{
ClpSimplex model;
int status;
// Keep names
if (argc<2) {
status=model.readMps("hello.mps",true);
} else {
status=model.readMps(argv[1],true);
}
if (status)
exit(10);
int numberColumns = model.numberColumns();
int numberRows = model.numberRows();
if (numberColumns>80||numberRows>80) {
printf("model too large\n");
exit(11);
}
printf("This prints x wherever a non-zero elemnt exists in matrix\n\n\n");
char x[81];
int iRow;
// get row copy
CoinPackedMatrix rowCopy = *model.matrix();
rowCopy.reverseOrdering();
const int * column = rowCopy.getIndices();
const int * rowLength = rowCopy.getVectorLengths();
const CoinBigIndex * rowStart = rowCopy.getVectorStarts();
x[numberColumns]='\0';
for (iRow=0;iRow<numberRows;iRow++) {
memset(x,' ',numberColumns);
for (int k=rowStart[iRow];k<rowStart[iRow]+rowLength[iRow];k++) {
int iColumn = column[k];
x[iColumn]='x';
}
printf("%s\n",x);
}
printf("\n\n");
return 0;
}
我已将 Include 和 Lib 目录与我在 Visual Studio 中的项目相关联，但是当我尝试构建时，会出现许多链接器错误，例如：
Simplex(void)" (??1ClpSimplex@@QAE@XZ) referenced in function _main
1>hello.obj : error LNK2019: unresolved external symbol "public: virtual __thiscall CoinPackedMatrix::~CoinPackedMatrix(void)" (??1CoinPackedMatrix@@UAE@XZ) referenced in function _main

1>hello.obj : error LNK2019: unresolved external symbol "public: __thiscall ClpSimplex::ClpSimplex(bool)" (??0ClpSimplex@@QAE@_N@Z) referenced in function _main
作为一个新手，我对如何解决这个问题一无所知，因为我的课程只涉及与代码语法相关的调试，而不是链接器问题。
任何提示或指向其他线程的链接都会有很大帮助。我一直在谷歌上搜索一整天，但不知所措......
