问题描述
我正在尝试编译以下代码:
I'm trying to compile the below code :
#include <cstdlib>
#define HAVE_STRUCT_TIMESPEC
#include <mgl2/mgl.h>
using namespace std;
int main() {
mglGraph gr;
gr.FPlot("sin(pi*x)");
gr.WriteFrame("test.png");
return 0;
}
我正在使用Netbeans IDE，Win 10 64x ....但一直出现此错误:
I'm using Netbeans IDE , Win 10 64x .... but keep getting this error :

推荐答案
您需要告诉链接程序一个包含所有mathGL函数的库名称.在Netbeans 8.2中，您可以通过以下方式做到这一点(我假设您的项目是"C/C ++应用程序"):
You need to tell linker a library name, containing all the mathGL functions. In Netbeans 8.2 you can do that in the following way (I'm assuming your project is "C/C++ Application"):
- 打开您的项目属性
- 点击左侧窗格中的链接器"
- 找到库"行，然后单击右侧带有"..."的按钮
- 在右窗格中单击添加选项..."
- 选择其他选项"并键入"-lmgl"
- 点击确定"
- 重建项目
最后一个名为选择选项"的弹出窗口应如下所示:
This final popup window, titled "Select Option", should look like this:
