未定义对GetStockObject @ 4的引用 [英] Undefined reference to GetStockObject@4

问题描述

我已经在Eclipse/MinGW/C中创建了一个程序(项目类型:C)，该程序应该只显示一个空窗口.它也有以下一行:

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:

wndclassex.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);

对 GetStockObject()的调用会产生编译器错误:

The call to GetStockObject() produces a compiler error:

Z:/mtsts_workspace/MTSTS/Debug/../WinMain.c:29:未定义的引用`GetStockObject @ 4'

Z:/mtsts_workspace/MTSTS/Debug/../WinMain.c:29: undefined reference to `GetStockObject@4'

有人知道出什么事了吗?

Has anyone an idea what's wrong ?
