今天在某台64位LInux下编译一个简单的hello world的C程序，报错：

/usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../crt1.o: could not read symbols: File in wrong format

查看该文件的格式，竟然是32位的：

# file /usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../crt1.o
/usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../crt1.o: ELF 32-bit LSB relocatable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.18, not stripped

查看glibc-devel版本：

# yum info glibc-devel
