make: *** 错误 1
$

编译程序的时候无缘无故就出现这个问题。起先还以为是自己程序的问题，后来又编译以前正确的代码，同样出现类似上面红色字体的问题。
我是：
qmake -project
qmake -makefile
make
这样来的。之前的代码都没有出现问题过,所以我怀疑是自己电脑上的gcc的问题。有解决办法吗？
附用来调试的代码段：

#include <iostream>
#include <string>
using namespace std;

int main () {
string numerics("0123456789");
string name("r2d2");
string::size_type pos =name.find_first_of( numerics);
cout <<pos<<"----"<<name[pos]<<endl;
return 0;

}

qmake是qt程序的编译器，你写的又不是qt程序，只是一般的c++代码，请你直接执行g++ source.cpp

用qmake照样可以，不是吗？我也试过用g++ main.cpp，同样出现类似上面红色字体得错误。而且这段程序原本是可以用的。后来做了些修改，就编译出错。我一般会留个备份的，所以原先正确的代码还在，但是同样调试出错。错误如上红色部分。

同样谢谢cjacker，我下次贴帖子的时候会注意的。

aaaaa007 发表于 2006-6-23 10:24:24

qmake其实本质上用的好像还是gcc，所以我觉得用qmake 还是直接g++应该没有问题的。

haulm 发表于 2006-6-23 10:32:09

qmake是qt的一个指令程序，位置在/usr/lib/qt-3.3/bin，/usr/bin/qmake是它的链接。

使用qmake会告诉gcc编译器现在编译的是qt的GUI程序，而不是你现在写的终端对话程序，所以你的代码就一定是错误连连。

aaaaa007 发表于 2006-6-23 10:36:22

版主可以试一下：
qmake -project
qmake -makefile
make
用了就知道他也完全可以用来调试纯的C＋＋代码的。
至少我是。
似乎偏离主题了哦，还是不知道g++出了什么问题。

haulm 发表于 2006-6-23 11:16:00

Sorry，我现在才知道qmake也可以用来编译console程序。

aaaaa007 发表于 2006-6-23 11:26:42

g++ main.cpp 现在又可以了，就刚才在qmake上的纠扯向版主道歉。
但是以前用qmake可以编译的代码现在用qmake就出错，错误如帖子红色部分。
既然g++没有错误，那应该就是qmake的问题了，难道Qt出错了？

haulm 发表于 2006-6-23 11:35:05

因为以前我用qmake曾经不能编译console程序，所以可能和qmake的版本有关吧。

cjacker 发表于 2006-6-23 11:40:15

我说你的代码不干净不是说你的帖子不干净。

而是说你出错的那个cpp里面确实存在看不到的特殊字符，比如特殊的blank之类的。

所以，用gedit,kedit之类的可以过滤一下子。

尤其粘贴拷贝容易出现这种问题。

yunfan 发表于 2006-6-23 12:09:14

不要直接从网页上复制代码下来, gcc报的就是有不可读字符的错误.

:twisted:

cjacker 发表于 2006-6-23 12:37:33

总算找到一个知音了。

yunfan 发表于 2006-6-23 13:11:33

:mrgreen:嘿嘿, 我以前也犯过这种错误,因为记性差, 还不只犯一次.:neutral:

aaaaa007 发表于 2006-6-23 14:47:58

我的代码都是纯手工录入的。
不过现在qmake又可以了，我什么都没有做，或许真的是特殊字符的错误。
就到这里了，在此谢谢各位。
