使用DEV-C++进行命令行编译的设置问题

[碧蓝右耳]

我下载安装了DEV-C++ V4.9.8.0
操作系统Windows2000 professional,装在C盘
DEV-C++安装在D:\TOOL\DEV-CPP
我的源代码在E;\CPP

现在情况是，我写了一个程序，001.cpp 如下：

#include <iostream.h>

int main()
{
cout << "hello world" << endl;
return 0;
}

我在命令行下
使用VC编译，进VC的目录，cl 001.cpp，通过
使用free的BCB5.5,生成了bcc32.cfg文件后，进BCB55目录，bcc32 001.cpp ,通过
在DEV-C++的IDE环境下，建立工程，加入001.cpp,编译运行通过

！！！但是
在命令行下，进入 d:\tool\dev-cpp\bin,
g++ 001.cpp
报错，声称 iostream: no such file or directory

即使加上 -I"d:\tool\dev-cpp\include",
或是 -I"d:/tool/dev-cpp/include",也没用

为何
为排除源文件的影响，我已经把 001.cpp复制到于编译器同一目录

这应该是GCC的设置吧，怎么设呢，我可不想每个小小的程序都生成一个工程文件

首先，g++ 的命名行：
g++ -o 001.exe 001.cpp

其次，偶现在还用的 4960
偶从 Bloodshed 下载的 4980，从命令行编译，也是搞不定
4960 就没问题
偶也不知是偶的设置哪儿有问题，还是别的什麽

[碧蓝右耳]

主要问题是
无法包含头文件和库啊

[Zeroins]

^-^
偶的现象和楼主一样

高人指点之前，还是先用其他版本的吧

中秋快乐

[碧蓝右耳]

求高人指点

下载: MinGW.
http://prdownloads.sourceforge.net/mingw/MinGW-3.1.0-1.exe?download

安装,安装路径为 D:\tool\Dev-Cpp

安装完成后.
设置 系统变量 path=D:\tool\Dev-Cpp\bin;%path%

就可以用了. 象上面的源代码 只用 g++ hello.cpp 就可以搞定. 不用 -I -L等参数.

不过装个 Cygwin 应该更好用,我一直用她!

没有高人吗

不能用iostream.h，如下：
#include <iostream>
using namespace std;

[碧蓝右耳]

没用，一样的，出错信息为
001.cpp:1:20: iostream: No such file or directory
001.cpp: In function `int main()':
001.cpp:6: `cout' undeclared (first use this function)
001.cpp:6: (Each undeclared identifier is reported only
it appears in.)
001.cpp:6: `endl' undeclared (first use this function)

[碧蓝右耳]

如果换成 c++ -I"d:\tool\dev-cpp\include" 001.cpp
出错信息就成了

GCC(MinGW)编译器中没有iostream.h这个文件.只有 iostream 文件.
你写的不是标准C++程序.
=========================
#include <iostream>

using namespace std;

int main (int argc, char *argv[])
{
cout << "Hello World!" << endl;
cout << "Press ENTER to continue..." << endl;
cin.get();
return 0;
}
===========================
-I"D:/tool/Dev-Cpp/include/c++"

[碧蓝右耳]

没有用
我试过N次各种组合
包括 /和\的变化
iostream.h 和 iostream 的变化
中文输入和英文输入的变化

[碧蓝右耳]

在IDE环境是可以编译通过的

[Zeroins]

各位还是用过 4.9.8.0 再说吧
程序肯定没有问题
4960 也没问题
只有 4980 的命令行通不过

[碧蓝右耳]

在Dev-Cpp 4.9.8.0 的IDE环境下，打开001.cpp文件
执行编译运行（F9），编译通过
在编译日志里的纪录是:

执行 g++.exe ...
g++.exe "d:\tool\dev-cpp\bin\001.cpp -o"d:\tool\dev-cpp\bin\001.exe" -I"d:\tool\dev-cpp\include\c++" -I"d:\tool\dev-cpp\include\mingw32" -I"d:\tool\dev-cpp\include\backward" -I"d:\tool\dev-cpp\
include" -L"d:\tool\dev-cpp\lib"

可见，Dev-Cpp执行的就是上面的命令，但是把上面的命令在命令行中输入时，就不可行了

[wengang]

g++ 的编译速度真的不敢恭维啊!

[5852]

我也一直是编译的时候 出现
iostream.h: no such file or directory

真不知道是为什么

[cxjddd]

<iostream.h> 不是标准支持的。

你应该用 <iostream>。没什么，找本“现代”一点的书看一看。
