Question

我试图从这里的旧SDL教程构建这个示例程序dots.c。 http://www.dreamincode.net/forums/topic/64143-game-programming-in-linux-for-windows-programmers-part-2/我从GCC收到错误，我认为这可能与丢失的C转义序列有关，我的复制粘贴或原始HTML表示都省略了这些错误。但是，我不太了解C，不管怎么说。我想知道代码需要哪些更改来清除这些构建错误，理想情况是您如何识别这些错误。谢谢。

在第41,51,55,59行的/＆gt;＆＃39;形式的教程代码中有杂散HTML。必须在GCC成功构建之前删除这些HTML。感谢tkausl建议解决方案。
