CPP读取dbf文件
prop系统导出的交收数据为dbf文件格式，linux需要能够解析该格式文件，
找到一个开源库shapelib可以实现该功能；
1、下载库源码
http://download.osgeo.org/shapelib/
选择shapelib-1.4.0.zip这个版本；
2、解压下载的源码，编译，
[fm@vm178 dbf_demo]$ ./configure --prefix=/home/fm/dbf_demo/shapelib
此时会在源码目录生成MakeFile文件，注意修改以下地方
目的是不让编译contrib目录下面的例子代码，编译会报错；
执行 make & make install
源码编译安装完成；
3、编写测试例子代码：
[fm@vm178 dbf_demo]$ g++ -o test test.cpp -I ./shapelib/include/ -L ./shapelib/lib/ -lshp
test.cpp代码如下：
#include <stdlib.h>
#include <string.h>
#include "shapefil.h"
int main(
int argc,
char
** argv )
{
DBFHandle hDBF;
int *panWidth, i, iRecord;
char szFormat[32], szField[1024];
char ftype[32], cTitle[32], nTitle[32];
int nWidth, nDecimals;
int cnWidth, cnDecimals;
DBFHandle cDBF;
DBFFieldType hType,cType;
int ci, ciRecord;
/* -------------------------------------------------------------------- */
/* Display a usage message. */
/* -------------------------------------------------------------------- */
if( argc !=
2
)
{
printf(
"dbfinfo xbase_file\n"
);
exit(
1
);
}
/* -------------------------------------------------------------------- */
/* Open the file. */
/* -------------------------------------------------------------------- */
hDBF = DBFOpen( argv[1],
"rb"
);
if( hDBF ==
NULL
)
{
printf(
"DBFOpen(%s,\"r\") failed.\n", argv[1]
);
exit(
2
);
}
printf ("Info for %s\n",argv[1]);
/* -------------------------------------------------------------------- */
/* If there is no data in this file let the user know. */
/* -------------------------------------------------------------------- */
i = DBFGetFieldCount(hDBF);
printf ("%d Columns, %d Records in file\n",i,DBFGetRecordCount(hDBF));
/* -------------------------------------------------------------------- */
/* Compute offsets to use when printing each of the field */
/* values. We make each field as wide as the field title+1, or */
/* the field value + 1. */
/* -------------------------------------------------------------------- */
panWidth =
(int
*) malloc( DBFGetFieldCount( hDBF )
*
sizeof(int)
);
//按行读取
for( i =
0; i < DBFGetRecordCount(hDBF); i++
)
{
for(
int j =
0; j < DBFGetFieldCount(hDBF); j++
)
{
const
char
* pszVal = DBFReadStringAttribute( hDBF, i, j);
printf ("%s\n",pszVal);
}
}
DBFClose( hDBF );
return(
0
);
}
