[Dev-C++] A BIG BIG PROBLEM (AT LESS I THINK SO)

[Adrimort <adr...@te...>]

Hi!!! This is my 1st mail to the group. First of all sorry about my =
English. I expect you can help me:

I have used DevCpp for 2 months and all was perfect. But last week it =
started not to work properly. It compiles perfectly, showing the number =
of mistakes (yeah, I'm learning C++) I have, but when I have no =
mistakes, and the program is supposed to execute the program, an error =
message saying Compiler and linker output appears. The full message is =
this:
C:\WINDOWS\TEMP\ccdGLyfb.o(.text+0x50):mpp0202.cpp: undefined reference =
to `cout'

C:\WINDOWS\TEMP\ccdGLyfb.o(.text+0x55):mpp0202.cpp: undefined reference =
to `ostream::operator<<(char const *)'

C:\WINDOWS\TEMP\ccdGLyfb.o(.text+0x64):mpp0202.cpp: undefined reference =
to `cin'

C:\WINDOWS\TEMP\ccdGLyfb.o(.text+0x69):mpp0202.cpp: undefined reference =
to `istream::operator>>(int &)'

C:\WINDOWS\TEMP\ccdGLyfb.o(.text+0x89):mpp0202.cpp: undefined reference =
to `cout'

C:\WINDOWS\TEMP\ccdGLyfb.o(.text+0x8e):mpp0202.cpp: undefined reference =
to `ostream::operator<<(char const *)'

C:\WINDOWS\TEMP\ccdGLyfb.o(.text+0x9d):mpp0202.cpp: undefined reference =
to `cin'

C:\WINDOWS\TEMP\ccdGLyfb.o(.text+0xa2):mpp0202.cpp: undefined reference =
to `istream::operator>>(int &)'

C:\WINDOWS\TEMP\ccdGLyfb.o(.text+0xe4):mpp0202.cpp: undefined reference =
to `cout'

C:\WINDOWS\TEMP\ccdGLyfb.o(.text+0xe9):mpp0202.cpp: undefined reference =
to `ostream::operator<<(char const *)'

C:\WINDOWS\TEMP\ccdGLyfb.o(.text+0xf4):mpp0202.cpp: undefined reference =
to `ostream::operator<<(int)'

C:\WINDOWS\TEMP\ccdGLyfb.o(.text+0xff):mpp0202.cpp: undefined reference =
to `ostream::operator<<(char const *)'

What happens?? What can I do?? I have tried reinstalling the program and =
even installing 4.01 version, but it doesn't work.

Thanks for all.
