Hi I am trying to compile 32 bit version on AMD 64 with ( I got the following from the FAQ) ./configure --target=athlon_xp --cc="gcc -m32" --as="as --32" --with-extralibdir=/usr/lib I get messages of: Assembler Message: Error bad register name '%rbx' What do I do with that??? I am using centos 5 and an AMD 4200+ X2. Jerry
