Undefined reference to GetStockObject@4
提问by Marcus Tik
I've created a program in Eclipse / MinGW / C (project type: C) which should just present an empty window. It also has the folowing line:
我在 Eclipse/MinGW/C（项目类型：C）中创建了一个程序，它应该只显示一个空窗口。它还具有以下行：
wndclassex.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
The call to GetStockObject()produces a compiler error:
调用GetStockObject()产生编译器错误：
Z:/mtsts_workspace/MTSTS/Debug/../WinMain.c:29: undefined reference to `GetStockObject@4'
Z:/mtsts_workspace/MTSTS/Debug/../WinMain.c:29: 未定义对`GetStockObject@4'的引用
Has anyone an idea what's wrong ?
