使用 gcc 構建 GLAD 時出錯

Question

我遇到了高興的麻煩。 我已經使用此配置下載了源文件：

• 語言 - C/C++
• 規格 - OpenGL
• API - gl 版本 4.6
• 簡介 - 核心
• 生成加載器被選中

解壓檔案后，我得到了這個結構（現在盡可能簡單）：

project/
    main.c
    glad.h
    glad.c
    khrplatform.h

我的main.c是這樣的：

#include "./glad.h"
#include <GLFW/glfw3.h>

int main() {
    return 0;
}

最后，我嘗試用gcc編譯它，因為我的項目將在c中：

gcc main.c glad.c -lglfw -lGL -ldl -I. -o run

但我得到了這些錯誤：

glad.c:1328:1: error: unknown type name ‘PFNGLRENDERBUFFERSTORAGEMULTISAMPLEEXTPROC’; did you mean ‘PFNGLRENDERBUFFERSTORAGEMULTISAMPLEPROC’?
 1328 | PFNGLRENDERBUFFERSTORAGEMULTISAMPLEEXTPROC glad_glRenderbufferStorageMultisampleEXT = NULL;

      |                                                                                         ^~~~
      |                                                                                         ;

這段代碼對我來說真的很奇怪，但它來自圖書館，所以我自己改變它看起來不太好......

只要確保下載正確的 GLAD 配置，就可以了。
