Hi Chris, Thanks for your response. Is there any way to find out which files are in 32 bit or 64 bit?

No, I meant this: ld: fatal: file /usr/local/mysql/lib/libmysqlclient.so: wrong ELF class: ELFCLASS64 ld: fatal: file ext/libxml/.libs/libxml.o: wrong ELF class: ELFCLASS32 You can't (as far as I know) have some libraries that are 64 bit and others that are 32. It's either all 64, or all 32. Your operating system should install one type or the other. -- Postgresql & php tutorials http://www.designmagick.com/
