xinyiZzz opened a new pull request #7911:
URL: https://github.com/apache/incubator-doris/pull/7911

   ## Problem Summary:
   
   Error details in be.out:
   ````
   /home/disk3/zxy/baidu/bdg/doris/core/output/be/lib/palo_be: 
/lib64/libc.so.6: version `GLIBC_2.18' not found (required by /home/disk3/zxy/ 
baidu/bdg/doris/core/output/be/lib/palo_be)
   ````
   
   nm looks at palo_be and finds that the method that depends on GLIBC_2.18 is 
`__cxa_thread_atexit_impl`
   
![3be717fca2b8563d447aa1e1c8f1f39a](https://user-images.githubusercontent.com/13197424/151341978-1ecc157e-3178-4fed-b824-08c60f873ec2.png)
   
   I found that the `__cxa_thread_atexit_impl` method was introduced by glibc 
to support thread_local variables
   
https://sourceware.org/glibc/wiki/Destructor%20support%20for%20thread_local%20variables
   
   It was no problem to compile through gcc10 before, our development machine 
glibc version only reaches GLIBC_2.12, and it is not allowed to upgrade the 
glibc version...
   
   So, how can I avoid this problem, please help
