Why dependent on a specific C runtime version?

[Lin George]

Hello everyone, 


Why running a program on a specific platform (Linux), there are runtime errors 
which mentions that specific LIBC runtime version is required (for example, 
GLIBC_2.3.3). 

I think C runtime should be compatible (means using one version of gcc to build 
a program, it should be able to run on platform which contains another version 
of gcc runtime). I am not sure whether this error is caused by some wrongly 
used compile/link options (which binds this program to specific C runtime 
version)? 


thanks in advance, 
George
