错误：iostream.h由于包括cplex [英] error: iostream.h due to including cplex

问题描述

我试图在Ubuntu 12.04中使用eclipse中的cplex，但是当我包含ilocplex.h时，我收到以下错误

  /opt/ibm/ILOG/CPLEX_Studio124/concert/include/ilconcert/ilosys.h:360:22：致命错误：iostream.h：没有这样的文件或目录
  

只有两个包含如下：

  #include< ; ilcplex / ilocplex.h> 
 #include< iostream> 
  

如果有人可以帮助我，我将不胜感激。

解决方案

当ILOG的Concert库首次发布时，较早的iostream.h头文件在C ++编译器中仍然很常见，但它支持标准的iostream库。要使用标准标头和库，您需要定义 IL_STD 预处理器符号。在Eclipse / C ++中定义预处理指令的说明可以在这个问题。

I am trying to use cplex in eclipse in Ubuntu 12.04 but when I include ilocplex.h I get the following error

/opt/ibm/ILOG/CPLEX_Studio124/concert/include/ilconcert/ilosys.h:360:22: fatal error: iostream.h: No such file or directory

The only two includes are written as follows:

#include <ilcplex/ilocplex.h>
#include <iostream>

I would appreciate if anyone could help me with this.

解决方案

At the time ILOG's Concert library was first released, the older iostream.h headers were still common in C++ compilers, but it supports the standard iostream libraries. To use the standard headers and libraries, you need to define the IL_STD preprocessor symbol. Instructions for defining preprocessor directives in Eclipse/C++ can be found in this question.
