一些c++經常使用庫

jsoncpp

https://sourceforge.net/projects/jsoncpp/

安裝scons

yum install scons
cd jsoncpp-src-0.5.0
scons platform=linux-gcc
cp -r jsoncpp-src-0.5.0/include/json  /usr/local/include
cp jsoncpp-src-0.5.0/libs/linux-gcc-4.4.7/libjson_linux-gcc-4.4.7_libmt.so /usr/local/lib/libjson.so

log4cxx

using namespace log4cxx;
using namespace log4cxx::helpers;
int main(){
    PropertyConfigurator::configure("./log4cxx.properties");
    LoggerPtr logger = Logger::getRootLogger();
    LOG4CXX_INFO(logger,"This is a test");
    return 0;
