Hi there,

I am always getting following errors when compiling my c++
program in Visual Studio 6.0:

--------------------Configuration: testgenreg - Win32
Release--------------------
Compiling...
testgenreg.cxx
C:\Program Files\Microsoft Visual Studio\VC98\INCLUDE\vector(221) :
error C2039: 'swap' : is not a member of 'std'
C:\Program Files\Microsoft Visual
Studio\VC98\INCLUDE\vector(220) : while compiling class-template member
function 'void __thiscall std::vector<unsigned int,class
std::allocator<unsigned int> >::swap(class std::vector<unsigned
int,class std:
:allocator<unsigned int> > &)'
C:\Program Files\Microsoft Visual Studio\VC98\INCLUDE\vector(221) :
error C2660: 'swap' : function does not take 2 parameters
Error executing cl.exe.

testgenreg.exe - 6 error(s), 0 warning(s)

I am not using any STL class directly. I even minimize my main
program to int main(){return 0;}. But it still gives same errors.
However, since the code compiles under linux using g++. I guess
there must be something related to Visual Studio.

Any help is appreciated.

(guess) try to include <algorithm> before <vector>

thanks. this problems is solved
by removing the namespace std{}
which contains those standard headers.

I mean from

namespace std
{
#include <algorithm>
#include <vector>
// some other headers
}

=>

#include <algorithm>
#include <vector>

You should never re-namespace system headers (or any headers, really) - it
can cause all kinds of trouble, as you've seen. Other things may refer to
them with a fully qualified namespace (and not be able to find them), and
all sorts of bad stuff like that.

If Innersmile's example was truly representative, the declarations of list
&c would be in namespace std::std.
