c - 错误 : expected '=' , ','、 ';'、 'asm' 或 '__attribute__' token 之前的 '*'

Question

我对 Unix 非常非常新，但在 C 方面有经验。我不确定这个消息是否适合 Unix 论坛(如果有的话)或 C。但是，因为它是一个编译错误，我觉得它最适合这里。

我对名为 ioquake3 的程序进行了“编译”。我收到这些错误。我试着用谷歌搜索它们。这些错误似乎是由双重包含或类似的原因引起的。 我无休止地尝试查看如何对代码进行写入编辑。但是，我无法修复它。

提前谢谢你。

在gcc中，错误:

expected '=', ',', ';', 'asm' or '__attribute__' before '*' token

通常与 typedef 相关联，当您使用它时，它不在范围内。例如下面的程序:

mytype fn(int n) { return (mytype)n; }
int main(void) { return 0; }

当你试图编译它时产生这个错误:

prog.c:2: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'fn'

如果您在文件顶部插入 typedef int mytype; 行，它可以编译。

现在有点难以辨别代码中哪些精确行映射到错误中列出的行号，但我的第一个猜测是您没有包含 CURL 头文件。这似乎是你有这样的行的情况:

extern CURL* (*qcurl_easy_init)(void);

但是您似乎没有在任何地方包含可以为您提供 CURL 类型定义的头文件。

您确实有以下代码:

#ifdef USE_LOCAL_HEADERS
  //#include <../libcurl/curl/curl.h>
#else
  //#include <../libcurl/curl/curl.h>
#endif

但这看起来像是您从网页的“查看源代码”表示中复制了这些内容，只是在它们不起作用时将它们注释掉了。您可能需要的是:

  #include <../libcurl/curl/curl.h>

当然，调整头文件的实际位置。
