[Linker error] undefined reference to `operator delete(void*)'

Pretty mysterious linking error:

And this is the snipped-down code that generates the error:

1class particle{
  float x,y, vx, vy;
  int type, life, col, size;
  public:
      particle(int t, float _x, float _y){
          ...
          }
      void draw(BITMAP *buf){
          ... 
          }
      int update(){
          ...
          }
  };
  
16class ccomet {
  vector<particle> trail;
  int x,y;
  public:
      ccomet(int a, int b){
          x = a;
          y = b;
          for(int x=0; x<100; x++){
              trail.push_back(particle(tCOMET, (float)x, (float)y));
              }
          }
      void draw(BITMAP *buf){
          for(int x=0; x<trail.size(); x++){
              trail[x].draw(buf);
              }
          }
      void update(){
          vector<particle>::iterator p;
          for(p = trail.begin(); p!=trail.end(); p++){
              if(p->update()){//is dead
                  trail.erase(p);
                  p--;
                  }
              }
          }
      ~ccomet(){
          trail.empty();
          }
  
  }*com;

It actually compiled fine, but as soon as i added com = new ccomet(20,20); that nasty error popped out.
Its been quite some time from the last time i programmed, so it could be something stupid...

Use gpp.exe instead of gcc.exe.

FMC

err... stupid IDE why on earth did it choose to use gcc?
thanks!

You didn't link the C++ runtime library. Note that it doesn't be included by gcc automaticly. Some gcc compilers named it "libc++" some others (DJGPP if I remember correctly) named it "libcxx" so you must add either "-lc++" or "-lcxx" at the link command.

[edit]Too slow... and gpp includes the C++ runtime library automaticly.[/edit]
