Hello gcc-help members
I have a small program which I get compiled using gcc version 2.95.3
20010315 (SuSE) without problems. I doesn't compile for a newer version,
namely gcc version 3.3 20030226 (prerelease) (SuSE Linux). The small
program reads as follows:
#include<iomanip>
#include<iostream>
class myostream
{
std::ostream &out;
int mode;
public:
myostream(std::ostream &outi, int m = 1): out(outi), mode(m)
{
if (mode == 1)
out <<'@';
if (mode == 2)
mode=1;
}
myostream &operator<<(double d){
out << d;
return *this;
}
myostream &operator<<( std::smanip<int> );
};
myostream &myostream::operator<<( std::smanip<int> s)
{
out << s;
return *this;
}
int main(int argc, char *argv[])
{
myostream myout(std::cout,1);
double f = 5.675566;
myout << std::setw(18) << f ;
return 0;
}
Attached is the *.ii file and the output I got after compiling this small
program (let's call it test.C) with the following command:
g++ -v -save-temps -Wall -o test test.C
Sorry for the bad way I posted this problem. I haven't done that before.
Best regards
Kevin Brinkmann
