dev c++编译时链接出错
程序很简单，从一个控制台应用程序中弹出一个windows对话框。但编译时总是出错，请指点
编译错误如下：

[Linker error] undefined reference to `GetOpenFileNameA@4'
[Linker error] undefined reference to `CommDlgExtendedError@0'
ld returned 1 exit status
C:\Program Files\DEV-CPP\工程\Makefile.win [Build Error] [condlg.exe] Error 1

[解决办法]
没加库文件

连接命令里加 -lcomctl32
[解决办法]
工程属性－>参数->linker加上：-lgdi32 -lcomdlg32
[解决办法]
-lcomctl32
