我现在正在使用 pocketSphinx 来构建一个 C 库。问题是,如果我将 main 函数与所有头文件(如下代码)放在一起,它工作得很好。然后我做了一个静态库(代码不包括主函数)。但是当我试图在另一个主函数中使用这个库时,错误发生了:
/usr/local/include/sphinxbase/ad.h:106:27:致命错误:sphinx_config.h:没有这样的文件或目录
...编译时。我认为这可能是与我的头文件路径有关的问题。
谁能告诉我如何解决这个问题?
下面的代码运行良好:
//system headerfiles
#include <stdio.h>
#include <string.h>
#include <sys/types.h>
#include <sys/time.h>
#include <signal.h>
#include <setjmp.h>
//用于录制和播放的通用实时音频接口
#include <sphinxbase/ad.h>
#include <sphinxbase/cont_ad.h>
//pocketsphinx 头文件
#include <sphinxbase/err.h>
#include "pocketsphinx.h"

正如我所说,当我用上面的代码和如下的头文件制作一个库时:
#ifndef MIC_RECOG_H
#define MIC_RECOG_H
char const *recognize_from_microphone();
#endif
使用这个库时会发生“没有头文件问题”。
