linux系统安装zint

背景：

　今天代码拉下了发现启动时报错，一看原来是同事用了zint的gem,我又没安，然后花了点时间解决，但其中踩了几次坑，所以打算记录下：

一、zint开源库的介绍

zint 是一个开源的条码编码库，它支持超过50种条码，包括 Code-128, Data Matrix, EAN-128, UPC/EAN, ITF, QR Code, Code 16k, PDF417, MicroPDF417, LOGMARS, Maxicode, GS1 DataBar, Aztec, Composite Symbols 等等，基本上你见过的条码都能用它来进行编码，它支持直接输出 PNG 格式的图像文件和位图的字节数组。

它的开源项目介绍页面，https://sourceforge.net/projects/zint/ 可自行阅读。

二、zint源码在linux平台下的编译和安装

编译平台介绍：

系统版本：Red Hat Enterprise Linux6

Linux内核版本：Linux localhost.localdomain 2.6.32-71.el6.i686 #1 SMP Wed Sep 1 01:26:34 EDT 2010 i686 i686 i386 GNU/Linux

gcc版本： 4.4.4 20100726 (Red Hat 4.4.4-13) (GCC)

zint版本：zint-2.4.3

Mac

如果您是mac的话只需执行命令即可 brew install zint

Linux

编译步骤：

1) 下载源码

在开源页面中下载到对应版本的zint源码；

https://sourceforge.net/projects/zint/files/zint/2.4.3/

笔者下载的版本是zint-2.4.3，对应的压缩包文件为 zint-2.4.3.tar.gz

将下载的源码放于一个新的linux的目录下，比如/zint_src

2) 解压源码

cd /zint_src

tar –xvf zint-2.4.3.tar.gz 解压到当前目录

解压完了之后，用ls看一下当前路径，如果有zint-2.4.3文件夹生成，且里面有文件，解压过程没有报错，则表示解压成功了。

3) 阅读编译指南

cd zint-2.4.3

vi readme-cmake

里面的内容如下：

how to :

mkdir build

cd build

cmake ..

make [-j nr_proc+1]

make install

4) 开始正式编译

mkdir build

cd build

cmake ..

执行后这句后，成功的话就会提示 Build files have been written to: /zint_src/zint-2.4.3/build

这个时候ls一下当前目录就会发现有makefile了，我们就可以使用make直接来安装了

make install

输入完后，会看到百分比提示了：

【笔者第一次make install报错了，是因为windows主机和linux虚拟机之间使用了共享文件，刚好做so文件软链接的时候就报错了，如下：】

[root@localhost build]# make install

make[1]: *** [backend/CMakeFiles/zint.dir/all] 错误 2

make: *** [all] 错误 2

[root@localhost build]#

如果按照一开始将源码放于/zint_src （非主机与虚拟机的共享目录），则可以很顺利的编译和安装，如下：

root@localhost build]# make install

Install the project...

-- Install configuration: "RelWithDebInfo"

-- Installing: /usr/share/cmake/Modules/FindZint.cmake

-- Installing: /usr/local/lib/libzint.so.2.4.1

-- Installing: /usr/local/lib/libzint.so.2.4

-- Installing: /usr/local/lib/libzint.so

到这里zint库就已经安装好了。

5) 测试zint和libzint

通过第4步后已经完成了安装，这个步骤我们来试一下zint和libzint如下：

先看下libzint是否安装成功，

[root@localhost build]# ls -al /usr/local/lib/libzint.so

lrwxrwxrwx. 1 root root 14 10月 16 17:20 /usr/local/lib/libzint.so ->

libzint.so.2.4

则正是zint动态库已经链接完成。

测试zint 如下：

在终端输入 zint –h

[liluchang@localhost src]$ zint -h

Zint version 2.4.1

Encode input data in a barcode and save as a PNG, EPS or SVG file.

-h, --help Display this message.

-t, --types Display table of barcode types

-i, --input=FILE Read data from FILE.

-o, --output=FILE Write image to FILE. (default is out.png)

-d, --data=DATA Barcode content.

-b, --barcode=NUMBER Number of barcode type (default is 20 (=Code128)).

--height=NUMBER Height of symbol in multiples of x-dimension.

-w, --whitesp=NUMBER Width of whitespace in multiples of x-dimension.

--border=NUMBER Width of border in multiples of x-dimension.

--box Add a box.

--bind Add boundary bars.

-r, --reverse Reverse colours (white on black).

--fg=COLOUR Specify a foreground colour.

--bg=COLOUR Specify a background colour.

--scale=NUMBER Adjust size of output image.

--directpng Send PNG output to stdout

--directeps Send EPS output to stdout

--directsvg Send SVG output to stdout

--dump Dump binary data to stdout

--rotate=NUMBER Rotate symbol (PNG output only).

--cols=NUMBER (PDF417) Number of columns.

--vers=NUMBER (QR Code) Version

--secure=NUMBER (PDF417 and QR Code) Error correction level.

--primary=STRING (Maxicode and Composite) Structured primary message.

--mode=NUMBER (Maxicode and Composite) Set encoding mode.

--gs1 Treat input as GS1 data

--binary Treat input as Binary data

--notext Remove human readable text

--square Force Data Matrix symbols to be square

--init Create reader initialisation symbol (Code 128)

--smalltext Use half-size text in PNG images

--batch Treat each line of input as a separate data set

error: No data received, no symbol generated

能看到版本信息，证明zint这个bin文件已经安装好了。

至此zint和libzint的安装已全部结束，笔者在安装的过程中，几乎使用的默认路径，感兴趣的童鞋可以试着修改一些自定义的安装路径，可以定制化自己的zint和libzint。
