Dear Laurent:

I am using P4 2.66 GHz processor. I think that it is i386 compatible processor.
This is the output produce from the command (uname -pa)

Linux localhost.localdomain 2.6.18-1.2257.fc5 #1 Fri Dec 15 16:06:24 EST 2006 i686 i686 i386 GNU/Linux

I am not sure about my gmp version. I check in the /usr/lib/ folder for the library and I saw

/usr/lib/libgmp.a
/usr/lib/libgmp.so
/usr/lib/libgmp.so.3
/usr/lib/libgmp.so.3.3.3
/usr/lib/libgmpxx.a
/usr/lib/libgmpxx.so
/usr/lib/libgmpxx.so.3
/usr/lib/libgmpxx.so.3.0.5

I don't understand what happened exactly with this.
Thanks again for your response.

Best regards,

Sophea
