Hi

I have a problem with convertion from c to cpp.
Simple file clear.c

_____________________
#include <curses.h>

int main(void)
{
  initscr();
  nodelay( stdscr, TRUE );
  keypad( stdscr, TRUE );
  cbreak();
  noecho();
  if (has_colors())
   start_color();

// CLS

  clear();
  refresh();

  endwin();
}
_____________________

I compile it using:
    gcc clear.c -o clear.exe -lcurso
and everything is fine.

After change clear.c to clear.cpp and compiling
    gpp clear.cpp -o clear.exe -lcurso
i've got erros:

d:/djgpp/tmp\cc0xLJtL.o(.text+0x7):clear.cpp: undefined reference to
`initscr(void)'
d:/djgpp/tmp\cc0xLJtL.o(.text+0x35):clear.cpp: undefined reference to
`start_color(void)'
d:/djgpp/tmp\cc0xLJtL.o(.text+0x49):clear.cpp: undefined reference to
`clearok(_win *, bool)'
d:/djgpp/tmp\cc0xLJtL.o(.text+0x60):clear.cpp: undefined reference to
`werase(_win *)'
d:/djgpp/tmp\cc0xLJtL.o(.text+0x8a):clear.cpp: undefined reference to
`wrefresh(_win *)'
d:/djgpp/tmp\cc0xLJtL.o(.text+0x92):clear.cpp: undefined reference to
`endwin(void)'
collect2: ld returned 1 exit status

it seems to not link curso library. Why? What to do, if I have to use c++?
