C庫在Linux

Question

我一直在努力爲我所需要的libxls.h頭文件中的某些功能的C代碼鏈接。我已經下載了相應的文件並按照安裝說明進行操作。這些文件還包含我試圖編譯的測試C代碼（test.c）。的結果如下：

1. 命令編譯test.c的文件 - GCC test.c的-lm

結果：

[root@XXXXXXX95549 test]# gcc test.c -lm 
test.c:28:24: error: libxls/xls.h: No such file or directory 
test.c: In function ‘main’: 
test.c:33: error: ‘xlsWorkBook’ undeclared (first use in this function) 
test.c:33: error: (Each undeclared identifier is reported only once 
test.c:33: error: for each function it appears in.) 
test.c:33: error: ‘pWB’ undeclared (first use in this function) 
test.c:34: error: ‘xlsWorkSheet’ undeclared (first use in this function) 
test.c:34: error: ‘pWS’ undeclared (first use in this function) 
test.c:39: error: ‘WORD’ undeclared (first use in this function) 
test.c:39: error: expected ‘;’ before ‘t’ 
test.c:53: error: ‘t’ undeclared (first use in this function) 
test.c:58: error: ‘tt’ undeclared (first use in this function) 
test.c:60: error: dereferencing pointer to incomplete type 
test.c:63: error: dereferencing pointer to incomplete type 
test.c:64: error: dereferencing pointer to incomplete type 
test.c:66: error: dereferencing pointer to incomplete type 
test.c:67: error: dereferencing pointer to incomplete type 
test.c:68: error: dereferencing pointer to incomplete type 
test.c:70: error: dereferencing pointer to incomplete type 
test.c:70: error: dereferencing pointer to incomplete type 
test.c:71: error: dereferencing pointer to incomplete type 

爲了解決這個問題，我複製的庫文件在「/用戶/包括」位置

之後對於相同編譯命令的結果是：

[root@XXXXXX95549 test]# gcc test.c -lm 
/tmp/cc8DJETV.o: In function `main': 
test.c:(.text+0x14): undefined reference to `xls_open' 
test.c:(.text+0xd4): undefined reference to `xls_getWorkSheet' 
test.c:(.text+0xe4): undefined reference to `xls_parseWorkSheet' 
test.c:(.text+0xf0): undefined reference to `xls_getCSS' 
test.c:(.text+0x49c): undefined reference to `xls_showBookInfo' 
collect2: ld returned 1 exit status 

請解釋我該如何解決這個問題。

代碼test.c的給出如下：提前

#include <stdio.h> 
#include <stdlib.h> 
#include <string.h> 
#include <ctype.h> 

#include <libxls/xls.h> 

int main() 
{ 

    xlsWorkBook* pWB; 
    xlsWorkSheet* pWS; 
    FILE *f; 
    int i; 

    struct st_row_data* row; 
    WORD t,tt; 
    pWB=xls_open("files/test2.xls", "ASCII"); // "KOI8-R" 

    if (pWB!=NULL) 
    { 
     f=fopen ("test.htm", "w"); 
     for (i=0;i<pWB->sheets.count;i++) 
      printf("Sheet N%i (%s) pos %i\n",i,pWB->sheets.sheet[i].name,pWB->sheets.sheet[i].filepos); 

     pWS=xls_getWorkSheet(pWB,0); 
     xls_parseWorkSheet(pWS); 
     fprintf(f,"<style type=\"text/css\">\n%s</style>\n",xls_getCSS(pWB)); 
     fprintf(f,"<table border=0 cellspacing=0 cellpadding=2>"); 

     for (t=0;t<=pWS->rows.lastrow;t++) 
     { 
      row=&pWS->rows.row[t]; 
      //  xls_showROW(row->row); 
      fprintf(f,"<tr>"); 
      for (tt=0;tt<=pWS->rows.lastcol;tt++) 
      { 
       if (!row->cells.cell[tt].ishiden) 
       { 
        fprintf(f,"<td"); 
        if (row->cells.cell[tt].colspan) 
         fprintf(f," colspan=%i",row->cells.cell[tt].colspan); 
        //    if (t==0) fprintf(f," width=%i",row->cells.cell[tt].width/35); 
        if (row->cells.cell[tt].rowspan) 
         fprintf(f," rowspan=%i",row->cells.cell[tt].rowspan); 
        fprintf(f," class=xf%i",row->cells.cell[tt].xf); 
        fprintf(f,">"); 
        if (row->cells.cell[tt].str!=NULL && row->cells.cell[tt].str[0]!='\0') 
         fprintf(f,"%s",row->cells.cell[tt].str); 
        else 
         fprintf(f,"%s","&nbsp;"); 
        fprintf(f,"</td>"); 
       } 
      } 
      fprintf(f,"</tr>\n"); 
     } 
     fprintf(f,"</table>"); 
     printf("Count of rows: %i\n",pWS->rows.lastrow); 
     printf("Max col: %i\n",pWS->rows.lastcol); 
     printf("Count of sheets: %i\n",pWB->sheets.count); 

     fclose(f); 
     xls_showBookInfo(pWB); 
    } 

    return 0; 
}
