Ubuntu 12.04下用g++编译cplex实例程序，配置、出现的问题，解决办法

比如我要编译的实例程序为ilomipex1.cpp。

编译:g++ -I/home/stan/cplex/opl/include -DIL_STD ilomipex1.cpp -c; 

-DIL_STD选项的作用是为了兼容旧版本的#include <iostream.h>出现的问题。

链接:g++ -L/home/stan/cplex/concert/lib/x86_sles10_4.1/static_pic -L/home/stan/cplex/cplex/lib/x86_sles10_4.1/static_pic ilomipex1.o -o ilomipex1 -lilocplex -lcplex -lconcert -lm -lpthread。。

Ubuntu g++编译cplex,加载链接库的顺序必须为: -lilocplex -lcplex -lconcert，而且要放在命令的最后部分，否则会提示undefined reference to cplexsomething。这点非常非常重要。。

至于网上有些人说链接不通过是因为g++版本太高，我的g++版本是4.5.2，链接没有问题。。

我也试着去安装过低版本的g++，如g++-3.3，版本太低，链接失败，同样出现以下错误：
