下载软件包:jsoncpp-src-0.5.0.tar.gz scons-2.1.0.tar.gz

# tar zxvf scons-2.1.0.tar.gz
# tar zxvf jsoncpp-src-0.5.0.tar.gz

设定环境变量【关键】,绝对路径
# export MYSCONS=解压的路径
# export SCONS_LIB_DIR=$MYSCONS/engine

# cd jsoncpp-src-0.5.0
# python $MYSCONS/script/scons platform=linux-gcc
编译成功后，在在jsoncpp-src-0.5.0/libs/目录下找到相应的*.a和*.so
