GLUT 问题:重新声明 c++ 内置类型'wchar_t'时出错
GLUT Problem: error redeclaration of c++ built-in type 'wchar_t'
刚安装了 GLUT 并给了我'error redeclaration of c++ built-in type 'wchar_t'
.我搜索了解决方案,发现我应该包括<graphics.h>
.但这样做并没有帮助。有什么帮助吗?
该代码是任何新的 glut 项目的默认值。
代码为:
/*
* GLUT Shapes Demo
*
* Written by Nigel Stewart November 2003
*
* This program is test harness for the sphere, cone
* and torus shapes in GLUT.
*
* Spinning wireframe and smooth shaded shapes are
* displayed until the ESC or q key is pressed. The
* number of geometry stacks and slices can be adjusted
* using the + and - keys.

就我而言,代码块正在设置编译器的路径,以在旧文件夹 C:\MinGW 下安装。当我更改为代码块目录中的安装时,编译有效:
在代码块中,转到设置-编译器-工具链可执行文件,将编译器的安装目录更改为代码块目录中的 MinGW 安装。 感谢@Joao佩德罗。
