编译DeSiNe时出错

Errors while compiling DeSiNe

本文关键字：出错 DeSiNe 编译      更新时间：2023-10-16

当我为项目DeSiNe运行make build[点击进入github页面]时，我得到了错误‘Topology’ does not name a type

$ make build

但是所包含的CCD_ 3确实包含

class Topology : public AbstractNetworkElement
{
    // Friend(s)

如何解决？

编辑：添加Topology类的前向声明会产生进一步的错误：

In file included from src/Algorithm/SamcraBAlgorithm.h:22:0,
                 from src/Algorithm/SamcraBAlgorithm.cpp:17:

                 from src/Network/Flow.h:20,

                        ^
make: *** [Algorithm/SamcraBAlgorithm] Error 1

基本上，该项目有四个主要的编译问题：

  • TopologyFactory和Topology类之间的循环包含依赖关系
  • 当打算用作typedef时，直接包含TString.h头
  • 缺少cstdlib/csdio-includes
  • 类定义中的成员初始化（在C++11之前不可用）

第一个修复方案涉及从Topology标头中删除TopologyFactory，从而打破循环include依赖关系。然后在需要的地方包括TopologyFactory标头。

第二个问题很容易修复：只需删除TString头includes，它就可以默认使用Utils/Types.h中的定义。

第三个修复是琐碎的：只需在需要的地方添加cstdio/cstdlib includes。

最后一个修复方案涉及将静态初始化移到定义文件中（可能作者使用的是一个扩展名为的旧编译器，允许这种类型的初始化）。

我在这个要点上做了一个补丁，这样你就可以看到变化了。该项目在Ubuntu 15.10上使用g++5.2.1进行编译。

代码中有一个交叉引用。

Topology.h包括TopologyFactory.h，反之亦然TopologyFactory。h包括Topology。h

修复它的最简单方法是将Topology类的前向声明添加到TopologyFactory中。h:

#ifndef TOPOLOGYFACTORY_H
#define TOPOLOGYFACTORY_H
...
class Topology;
class TopologyFactory
{

更正确的方法是尝试解决这些依赖关系，即不要在Topology.h中包含TopologyNetwork.h，然后在所有使用TopologyNework和Topology的cpp文件中添加两个include指令：

/*                                                                                                                                                                                             
        source file DesineModel.cpp for class: DesineModel                                                                                                                               
     ...
