Question

vi example.c

#include<stdio.h>
#include "flite.h"
register_cmu_us_kal();
int main(int argc,char** argv)
{
 cst_voice *v;
 if(argc!=2)
 {
  fprintf(stderr,"usage:file_test FILE\n");
  exit(-1);
 }
 flite_init();
 v=register_cmu_us_kal(NULL);
 flite_file_to_speech(argv[1],v,"play");
 return 0;
}

编译：桌面：

~/flite-1.4-release$ gcc example.c -I./include/ -L./build/i386-linux-gnu/lib -lflite -lflite_cmu_us_kal -lflite_cmulex -lflite_usenglish -lflite_cmu_us_rms -lflite_cmu_time_awb -lflite_cmu_us_slt -lflite_cmu_us_awb -lm -o example


example.c:3: warning: data definition has no type or storage class
example.c: In function â€˜mainâ€™:
example.c:13: warning: assignment makes pointer from integer without a cast

我已经探索了下面的lib文件夹的内容。

请帮我解决这个问题。

Answer 1

以下声明了一个带有未指定参数的函数，并返回int：

register_cmu_us_kal();

调用它时，将其结果分配给cst_voice*类型的变量：

v=register_cmu_us_kal(NULL);

编译器会警告您此转换。

我认为最好的做法是为register_cmu_us_kal提供适当的原型（可能包括相关的头文件）。

Answer 2

您可以通过更改方法声明来解决此问题：

register_cmu_us_kal();

要

cst_voice *register_cmu_us_kal();

这告诉编译器方法register_cmu_us_kal();返回cst_voice *而不是int这是默认值，当你指定它时：

v = register_cmu_us_kal(NULL);

首先，您使用参数调用函数，无需参数即可定义参数;其次，它会警告您尝试将int分配给cst_voice *。

警告：数据定义没有类型或存储类= flite编译警告
