Increasing The Number of Decimal Places in C/C++ whit GMP

[RobertoSantarem]

Could anyone help me?

I need to make some calculations using a precision very high, then I installed the Library "GMP 5.0.2" using the WebUpdade of "Dev-C++ 4.9.9.2", but when I try to compile a simple program the message:

[Linker error] undefined reference to'__gmpz_clear'
...

apear for me. My computer use the Windows XP and I know that I need to link outward this library but I'm not getting to do this.

Thanks
