Hi guys, I meet a building problem when I follow the tutorial to run python setup.py build in my server.

The key point I noticed that is undefined reference to aligned_alloc@GLIBC_2.16 and I also tried to search this but nothing got. Questions about this error has been many years ago, seems this rarely happens.

Actually I'm not that familar with CMake side, so maybe this is a stupid question. But if someone has meet the same problem please teach me how to solve it. So grateful!

System Info

• OS: Pop!_OS 21.10 x86_64
• Kernel: 5.16.11-76051611-generic
• libstdc++ Version: /usr/lib32/libstdc++.so.6 -> libstdc++.so.6.0.29
• g++ -dumpversion: 9.3.0
• Conda Version: 4.10.3
• Conda Env Python Version: 3.6

What I tried

1. Reinstall conda and conda env: the same problem happens;
2. Do not use conda env, instead of using system python env;
3. Upgrade system, including g++ and other libs;

What I guess

1. Conda's problem, maybe the Cython has some conflict with conda env?
2. Some out-of-date lib soft links, maybe can be fixed manually.

Sharing any ideas about this would be welcome and I would be so grateful.
