SystemC 验证构建错误“未定义的引用..”

Question

我遇到了一个问题，即无法构建任何包含任何 SCV 函数用法的代码。我正在使用 Eclipse 和 Cygwin。 这是我正在尝试构建和运行的简单代码：

#include <scv.h>

int sc_main (int argc, char* argv[]) {
// Int data type
int data = 100;
// Get the bitwidth of the data
int bitwidth = scv_get_extensions(data).get_bitwidth();
cout << "Width of data is "<< bitwidth << endl;
cout << "Value in data is ";
// Get the value in data and print to stdio
scv_get_extensions(data).print();
return 0;
}

但它有很多错误，大部分都是重复的。 这是其中的第一对：

我找到了答案！ Here 是它的链接，如果有人需要的话！ 只需更改添加 scv 和 systemc 库的顺序即可。
