老代码的纠错问题【iostream.h和fstream.h】

wxjiao

在Debian下面执行sudo make时，线上遇到了找不到gmake命令的问题，后来用sudo ln -s /usr/bin/make /usr/bin/gmake添加链接解决了该问题。

再执行sudo make时，出现了如下的错误问题。
cd ./src/app; gmake all
gmake[1]: Entering directory `/home/jjj/svp-1.0b0/src/app'
cd ../libvd; gmake all
gmake[2]: Entering directory `/home/jjj/svp-1.0b0/src/libvd'

gmake[1]: *** [libvd] 错误 2
gmake[1]: Leaving directory `/home/jjj/svp-1.0b0/src/app'
make: *** [app] 错误 2

按照网上的提示，将
#include <iostream.h>
改成了
#include <iostream>
using namespace std;

将
#include <fstream.h>
改成了
#include <fstream>
using namespace std;

再执行sudo make时又出现了错误
cd ./src/app; gmake all
gmake[1]: Entering directory `/home/jjj/svp-1.0b0/src/app'
cd ../libvd; gmake all
gmake[2]: Entering directory `/home/jjj/svp-1.0b0/src/libvd'

gmake[1]: *** [libvd] 错误 2
gmake[1]: Leaving directory `/home/jjj/svp-1.0b0/src/app'

顺便将程序代码用附件上传了，请高手指点，本人是菜鸟，解答的越详细越好，先行谢过了！！

其实没什么错误，就是有些声明和语法不对。

iostream.h不再直接包含了，而是包含iostream，然后使用std命名空间。fstream类似。
math.h中一些函数原型，跟它里面声明的不太一样。
现在的C++编译器不再支持函数定义中加默认值了，只可以在声明中加。

主要就这三条，改了就好了。

非常感谢naihe2010的帮助，使用您修改的版本，软件已经装好了。实在是没分悬赏了，只能口头感谢了呵。以后有问题还向您多请教。

晕。我还得倒贴点儿！
