Question

我现在正在使用pocketSphinx构建一个C库。问题是如果我把main函数和所有头文件放在一起（如下面的代码所示），它运行良好。然后我做了一个静态库（代码不包括main函数）。但是当我试图在另一个主函数中使用这个lib时，错误发生在：

/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。

任何人都可以告诉我如何解决这个问题吗？

以下代码效果很好：

//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 headerfiles

#include <sphinxbase/err.h>      
#include "pocketsphinx.h"

    float conf;  

    ps_seg_frames (iter, &sf, &ef);  
    pprob = ps_seg_prob (iter, NULL, NULL, NULL);  
    conf = logmath_exp(ps_get_logmath(ps), pprob);  
    printf ("%s %f %f %f\n", ps_seg_word (iter), (sf + start) / 100.0, (ef + start) /     100.0, conf);

}  
}

    if (setjmp(jbuf) == 0)   
        word = recognize_from_microphone();  

printf("%s\n", word);

        ps_free(ps);  
    return 0;  
 }

正如我所说，当我使用上面的代码和头文件创建一个lib时，如下所示：

#ifndef MIC_RECOG_H
#define MIC_RECOG_H

char const *recognize_from_microphone();

#endif

使用此lib时将发生“无头文件问题”。

Answer 1

将-I/usr/local/include/sphinxbase添加到正在使用的编译器选项集中。

-I <path>将path添加到正在搜索要包含的文件的广告位集中。

使用我自建的库时出错
