Thank you for all those who have given my advice. I decide to build gcc-3.0 from tar ball in /usr/local/.
But as the older version of gcc reside in /usr/bin and gcc-3.0 reside in /usr/local/bin, I will have two different versions of gcc in my path.
Should I specify the binary directory in configuration? ("srcdir/configure --bindir=/usr/") Or are there any alternatives to this problem? _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
