Probleme bei DLL-Erstellung und <vector>

[Stefan.Wagenbrenner]

Good morning,

I'm trying to write a dll using Dev Cpp 4. I'm able to compile the
following code, but the linker throws an error and no dll is produced:

#include <stdio.h>
#include <windows.h>
#include <vector>

// ... more code ...

vector<char> charSubstring (char *str, int start, int ende)
{
vector<char> subs;

for (int i=start; i<=ende; i++)
{
subs.push_back(str);
}
}

The linker tells me the following:

$_S_oom_malloc alloc template1iOUi+0x1a):maindll.cpp: undefined
reference to `endl(ostream &)`
$_S_oom_malloc alloc template1iOUi+0x1a):maindll.cpp: undefined
reference to `cerr`
$_S_oom_malloc alloc template1iOUi+0x1a):maindll.cpp: undefined
reference to `ostream:perator<<(char const *)`
gcc exited with status 1

When I use the code above in a "normal" program it works fine. Could
someone tell me what I´m doing wrong?


Thanks in advance

Well, endl; is std::endl; but your'e not showiing code using either, making
me think you're not shwoing the entire code? I dont' se a main function so
it's not complete. Try giving us a complete program that produces the
error. You say you expect an .exe to be produced, so need a main().

The rest of the code was produced by Dev Cpp, so I omitted it. The code
posted by me was the only code which I wrote.

I don`t want to produce a .exe, producing a .exe which uses the function
in a main() does not cause an error.

You'll probably have more luck on a windows group, this a tool rather
than a language problem.

vector<char> charSubstring (char *str, int start, int ende)
{

Are you missing a

using namespace std;

statement?

Sorry, I only now saw the "linker" part
