Thanks for you help. I have installed gcc-4.4.4-13.el6.x86_64. I compiled it under the Red Hat Enterprise Linux Server release 6.0. It seems to find libc.so in /lib64, but it should in /usr/lib64, because of /usr/lib64/libc_nonshared.a. I don't known how to change the linker to open /usr/lib64/libc.so.
