hircluster.c:218:9: 错误：隐式声明函数‘strerror_r’ [-Werror=implicit-function-declaration] strerror_r(errno, cc->errstr, sizeof(cc->errstr)); ^ cc1: all warnings being treated as errors

I have tested to build using ubuntu 20.04 with an older gcc 4.4 and cmake which seems to work (link to job). Are you building using CMake or directly via Makefile? Does it work if you add the define _GNU_SOURCE?

Ah, I see. I ran on master which has some changes that is not yet delivered.

You will very likely be able to build with your old gcc compiler using: CFLAGS="-D_XOPEN_SOURCE=600" make

as in this example for v0.10.0

Corrected by #157 which is included in 0.11.0.
