在Linux环境下使用FC14版本进行程序编译时，遇到ld命令提示未定义符号'clock_gettime@@GLIBC_2.2'的问题。通过在makefile中添加-lrt参数成功解决了该问题。

Linux(FC14)下编译程序时出现下面的问题：

/usr/bin/ld: libvalhalla-test.o: undefined reference to symbol
'clock_gettime@@GLIBC_2.2'
/usr/bin/ld: note: 'clock_gettime@@GLIBC_2.2' is defined in
DSO /lib/librt.so.1 so try adding it to the linker command line
/lib/librt.so.1: could not read symbols: Invalid operation
collect2: ld returned 1 exit status

This means that libvalhalla-test has to be linked explicitly with librt,
thus the fix proposed before (another one is to add explictly -lrt in
the corresponding Makefile).

网上的说法是在makefile中加上 -lrt , 试过，确实可以。。。
