> Hello,

> Thanks for a great website!

> I am unable to compile gmp-chudnovsky.c on my Linux PC.  The gmp library

> pi.c) as follows:
>
> [lloyd at localhost demos]$ [lloyd at localhost demos]$ gcc pi.c -lgmp
>
> I get the following output:
>
> /home/lloyd/tmp/ccGVTUBR.o: In function `my_sqrt_ui':
> pi.c:(.text+0x52): undefined reference to `sqrt'
> pi.c:(.text+0xdd): undefined reference to `sqrt'
> /home/lloyd/tmp/ccGVTUBR.o: In function `build_sieve':
> pi.c:(.text+0x1797): undefined reference to `sqrt'
> collect2: ld returned 1 exit status
>
> I can't figure out why the sqrt function seems hidden from the linker.

> I'd appreciate any help.
