错误：预期的声明说明符或'...'字符串常量前 [英] error: expected declaration specifiers or '...' before string constant

问题描述

我收到的模仿在另一个文件中使用特定行的错误。

I am getting an error on a specific line that mimics the usage in another file.

PyObject *pyCharGetHeight(PyChar *self, void *closure) {
  CHAR_DATA *ch = PyChar_AsChar((PyObject *)self);
  PyObject *height = NULL;
  if(ch != NULL) height = Py_BuildValue("s", charGetHeight(ch));
  return height;
}

PyChar_addGetSetter("height", pyCharGetHeight, NULL, "Returns character's height");

将返回下面的错误，PyChar_addGetSetter ...行

is returning the following error, PyChar_addGetSetter... line

错误：预期的声明说明符或Ⅰ型的字符串常量前

error: expected declaration specifiers or â...â before string constant

我使用的是以下包括：

#include <Python.h>
#include "../scripts/pychar.h"

和pychar.h确实定义PyChar_addGetSetter（）为原型这里：

And pychar.h does define PyChar_addGetSetter() as prototyped here:

void PyChar_addGetSetter(const char *name, void *g, void *s, const char *doc);

该功能是写在 ../脚本/ pychar.c 的如下：

void PyChar_addGetSetter(const char *name, void *g, void *s, const char *doc) {
  // make sure our list of get/setters is created
  if(pychar_getsetters == NULL) pychar_getsetters = newList();

  // make the GetSetter def
  PyGetSetDef *def = calloc(1, sizeof(PyGetSetDef));
  def->name        = strdup(name);
  def->get         = (getter)g;
  def->set         = (setter)s;
  def->doc         = (doc ? strdup(doc) : NULL);
  def->closure     = NULL;
  listPut(pychar_getsetters, def);
}

这似乎是一个结构或类型不被认可，我猜我的功能。

It seems like a structure or type is not being recognized, I am guessing my function.

推荐答案

它看起来像你想在.c文件的顶层调用函数。你不能做到这一点。

It looks like you're trying to call a function at the top level of a .c file. You can't do that.

该错误消息可能是一个更好一点，但它看起来像GCC是间preting这是试图说明一个名为 PyChar_addGetSetter 和/或类型声明该类型的全局变量，并不能跨preT它无论哪种方式，并且告诉你为什么试图failde。

The error message could be a little nicer, but it looks like gcc is interpreting this as an attempt to declare a type named PyChar_addGetSetter and/or to declare a global variable of that type, and failing to interpret it either way, and telling you why that attempt failde.
