http://oss.metaparadigm.com/json-c/ 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): File "/usr/local/app/qingtian/scons-2.1.0/script/scons",line 187,in <module> import SCons.Script ImportError: No module named SCons.Script 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
