CetOs6.5下 jsoncpp安装 NCURSES的安装

Posted 2022-12-05 一厘阳光

NCURSES的安装

在安装MySQL时,有时提示缺少ncurses库,只需执行以下命令即可

yum install ncurses-devel

 jsoncpp安装

1.安装环境： 
Python （自带） 
scons （用来编译jsoncpp） 
jsoncpp

2.从github下载最新版本jsoncpp 
https://github.com/open-source-parsers/jsoncpp

3.安装scons 
scons 官方网址 http://www.scons.org/ 
找到Redhat版的rpm（比如scons-2.5.0-1.noarch.rpm），然后直接点击安装即可。

4.编译jsoncpp 
进入到jsoncpp文件，然后在终端执行： 
sudo scons platform=linux-gcc 
这样就会在jsoncpp/libs/linux-gcc-x.x.x中找到两个库文件，一个静态库一个动态库。

5.编写测试程序：

<code class="hljs cpp has-numbering" style="padding: 0px; margin: 0px; display: block; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-preprocessor" style="padding: 0px; margin: 0px; color: rgb(68, 68, 68); box-sizing: border-box;">#include "json/json.h"</span>
<span class="hljs-preprocessor" style="padding: 0px; margin: 0px; color: rgb(68, 68, 68); box-sizing: border-box;">#include <iostream></span>
<span class="hljs-keyword" style="padding: 0px; margin: 0px; color: rgb(0, 0, 136); box-sizing: border-box;">using</span> <span class="hljs-keyword" style="padding: 0px; margin: 0px; color: rgb(0, 0, 136); box-sizing: border-box;">namespace</span> <span class="hljs-built_in" style="padding: 0px; margin: 0px; color: rgb(102, 0, 102); box-sizing: border-box;">std</span>;
<span class="hljs-keyword" style="padding: 0px; margin: 0px; color: rgb(0, 0, 136); box-sizing: border-box;">int</span> main()
  Json::Value  v;
   <span class="hljs-keyword" style="padding: 0px; margin: 0px; color: rgb(0, 0, 136); box-sizing: border-box;">return</span> <span class="hljs-number" style="padding: 0px; margin: 0px; color: rgb(0, 102, 102); box-sizing: border-box;">0</span>;
</code>

其实只要第一句没问题就OK了。

6.以上程序用到了json.h，所以需要告诉编译器json.h的位置，只知道json.h的位置还不够，还需要库。  我的文件结构如下：

<code class="hljs avrasm has-numbering" style="padding: 0px; margin: 0px; display: block; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">Lib所在目录:
   jsoncpp..
       libs..
           linux-gcc-<span class="hljs-number" style="padding: 0px; margin: 0px; color: rgb(0, 102, 102); box-sizing: border-box;">4.8</span><span class="hljs-number" style="padding: 0px; margin: 0px; color: rgb(0, 102, 102); box-sizing: border-box;">.2</span>..
                  libjson_linux-gcc-<span class="hljs-number" style="padding: 0px; margin: 0px; color: rgb(0, 102, 102); box-sizing: border-box;">4.8</span><span class="hljs-number" style="padding: 0px; margin: 0px; color: rgb(0, 102, 102); box-sizing: border-box;">.2</span>_libmt<span class="hljs-preprocessor" style="padding: 0px; margin: 0px; color: rgb(68, 68, 68); box-sizing: border-box;">.a</span>  libjson_linux-gcc-<span class="hljs-number" style="padding: 0px; margin: 0px; color: rgb(0, 102, 102); box-sizing: border-box;">4.8</span><span class="hljs-number" style="padding: 0px; margin: 0px; color: rgb(0, 102, 102); box-sizing: border-box;">.2</span>_libmt<span class="hljs-preprocessor" style="padding: 0px; margin: 0px; color: rgb(68, 68, 68); box-sizing: border-box;">.so</span> 
头文件所在目录:
  jsoncpp.. 
      include..
          json.. 
             json<span class="hljs-preprocessor" style="padding: 0px; margin: 0px; color: rgb(68, 68, 68); box-sizing: border-box;">.h</span></code>

这里在终端输入以下命令：

<code class="hljs lasso has-numbering" style="padding: 0px; margin: 0px; display: block; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">export LD_LIBRARY_PATH<span class="hljs-subst" style="padding: 0px; margin: 0px; color: rgb(0, 0, 0); box-sizing: border-box;">=</span><span class="hljs-string" style="padding: 0px; margin: 0px; color: rgb(0, 136, 0); box-sizing: border-box;">'/Your Path/jsoncpp/libs/linux-gcc-4.8.2'</span>

根据以上文件目录：
g<span class="hljs-subst" style="padding: 0px; margin: 0px; color: rgb(0, 0, 0); box-sizing: border-box;">++</span> <span class="hljs-attribute" style="padding: 0px; margin: 0px; box-sizing: border-box;">-I</span> <span class="hljs-string" style="padding: 0px; margin: 0px; color: rgb(0, 136, 0); box-sizing: border-box;">'/Your Path/include'</span> <span class="hljs-attribute" style="padding: 0px; margin: 0px; box-sizing: border-box;">-L</span> <span class="hljs-string" style="padding: 0px; margin: 0px; color: rgb(0, 136, 0); box-sizing: border-box;">'/Your Path/jsoncpp/libs/linux-gcc-4.8.2'</span> <span class="hljs-attribute" style="padding: 0px; margin: 0px; box-sizing: border-box;">-ljson_linux</span><span class="hljs-attribute" style="padding: 0px; margin: 0px; box-sizing: border-box;">-gcc</span><span class="hljs-subst" style="padding: 0px; margin: 0px; color: rgb(0, 0, 0); box-sizing: border-box;">-</span><span class="hljs-number" style="padding: 0px; margin: 0px; color: rgb(0, 102, 102); box-sizing: border-box;">4.8</span><span class="hljs-number" style="padding: 0px; margin: 0px; color: rgb(0, 102, 102); box-sizing: border-box;">.2</span>_libmt test_json<span class="hljs-built_in" style="padding: 0px; margin: 0px; color: rgb(102, 0, 102); box-sizing: border-box;">.</span>cpp <span class="hljs-attribute" style="padding: 0px; margin: 0px; box-sizing: border-box;">-o</span> main</code>

这里 -I 是指定头文件目录，-L 是指定lib目录，-ljson_linux-gcc-4.8.2_libmt 表示链接 lib目录下的libjson_linux-gcc-4.8.2_libmt.so 动态库。

export 每开一个终端就要输入一次，不然会出现error while loading shared libraries，这里暂时没去解决。

关于error while loading shared libraries 可以参考以下链接:  http://stackoverflow.com/questions/5357869/error-while-loading-shared-libraries

关于gcc命令不大明白可以参看以下链接:  http://www.cnblogs.com/ggjucheng/archive/2011/12/14/2287738.html#_Toc311642848

关于安装jsoncpp,参考链接:  http://blog.csdn.net/gogoytgo/article/details/46007689

在安装前需要安装scons：

1. scons是神马？

scons是linux下的自动构建工具，类似cmake。

2. 安装

wget http://prdownloads.sourceforge.net/scons/scons-2.2.0.tar.gz .

tar zxvf scons-2.2.0.tar.gz

cd scons-2.2.0

python setup.py install

正常情况下，scons将安装到$PYTHON_INSTALL_DIR/bin/下

走到这里已经安装OK了

3. hello world程序

三个文件hello.h hello.c main.c hello.h定义函数void hello(); hello.c中实现该函数，main.c中调用该函数。

编写SConstruct，scons构建时使用。内容如下：

Program('hello', ['hello.c', 'main.c'])

开始构建 

scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
gcc -o hello.o -c hello.c
gcc -o main.o -c main.c
gcc -o hello hello.o main.o
scons: done building targets.

此时二进制文件已经构建完成，scons贼好用。
