C++: Loop error: name lookup of `var' changed for new ISO `for' scoping... etc.

RHLinuxGUY · 02-27-2007, 01:54 AM

I'm getting an error(shown further below) when I try to copy values from a std::string vector to another std::string vector:

Using a similar command as the following:

Code:

g++ -g file.cpp -W -Wall -ansi -pedantic `sdl-config --cflags --libs` -lSDL -o file

The error:

Code:

p_keyboard.h:127: error: name lookup of `a_iter' changed for new ISO `for' scoping
p_keyboard.h:124: error:   using obsolete binding at `a_iter'

Here is the code in which it is happening in.

Code:

for (unsigned int a_iter = 0; a_iter < keys_.size(); ++a_iter); // Line 124
{
    keys[ keys.size() -1 ].resize(keys[ keys.size() -1 ].size() +1);
    keys[ keys.size() -1 ][ a_iter ] = keys_[ a_iter ]; // Line 127
}

`keys_' is a parameter to the function this block of code exists in.

It looks like this:

Code:

int function(/*...*/ std::vector<std::string> keys_  /*...*/);

`keys' is a variable in a public part of a class.

It looks like this:

Code:

std::vector<std::vector<std::string> > keys;

As you can see I am trying to copy over the information from each element of `keys_', to every new element of `keys[ keys.size() -1 ][ a_iter ]'.

What am I doing wrong?

Any lack of information on my part, please notify me(not that anyone wouldn't

), so I can fill in the void.

Thanks in advance!

You've got a semicolon at the end of the for line. I also know you're using VS2005, and VS2003 would not have caught this error.

Thanks!

You mean if ? I'm sure you mean that.

Yeah, suppose so. That error just seemed word-for-word what VS2005 produced, but I must have been imagining things
