tar -zxvf json-c-0.9.tar.gz
./configure --prefix=/usr/local/json-c-0.9(没有prefix选项，默认的是/usr/local/lib/)
make && make install
windows编译冲突问题
json_object.h 32 行
//typedef int boolean; modify by shenyu
typedef unsigned char boolean;
error while loading shared libraries: libjson.so.0:
root
vi /etc/ld.so.conf 最后添加一行
/usr/local/lib/libjson.so.0
jsoncpp
资源下载：
http://sourceforge.net/projects/jsoncpp/files/latest/download?source=files
tar -zxvf jsoncpp-src-0.5.0.tar.gz
linux 下安装需要先装 scons
http://www.scons.org
http://sourceforge.net/projects/scons/files/scons/2.1.0/scons-2.1.0.tar.gz/download
解压后:
cd /home/qingtian/scons-2.1.0
python setup.py install
python setup.py install --standard-lib 安装到python标准目录
cd /home/qingtian/jsoncpp-src-0.5.0
python /home/qingtian/scons-2.1.0/script/scons platform=linux-gcc
python /usr/local/app/qingtian/scons-2.1.0/script/scons platform=linux-gcc
生成文件目录：
/home/qingtian/jsoncpp-src-0.5.0/include
/home/qingtian/jsoncpp-src-0.5.0/libs/linux-gcc-4.1.2
cp /home/qingtian/jsoncpp-src-0.5.0 /usr/local/jsoncpp -r
cp /home/leoxshen/jsoncpp-src-0.5.0 /usr/local/jsoncpp -r
cp /usr/local/app/leoxshen/jsoncpp-src-0.5.0 /usr/local/jsoncpp -r
编译代码时引用即可
#错误处理
mqq@38_183:~/qingtian/jsoncpp-src-0.5.0> python /usr/local/app/qingtian/scons-2.1.0/script/scons platform=linux-gcc
Traceback (most recent call last):

如果安装不上，需要root权限，执行命令
python setup.py install --standard-lib 安装到python标准目录
