Static linking against libmysql on linux giving undefined references

Hi,

I have created a shared library that statically link against version 5.7.29 by libmysqlclient.a and it works well. But now when I try to link against version 8.0.20 of libmysqlclient.a, I get the following undefined references when I run the ld command:

undefined reference to ’operator delete(void*, unsigned long)'
undefined reference to ’std::__throw_out_of_range_fmt(char const*, ...)'

I have also tried to link a regular application statically against version 8.0.20 of libmysqlclient.a, but then I got even more undefined references.

Development environment is Red Hat Enterprise Linux 7.7 (x86, 64-bit) and gcc 4.8.5.
Compiler options: -std=c++0x –D_GNU_SOURCE –O0 –g3 –Wall –c –fPIC – MMD –MP
Link options: –shared –lpthread –lc –lrt –ldl –lssl -lcrypto -lresolv

My question is:

1. Are there any changes in libmysqlclient.a between 5.7.29 and 8.0.20 that could explain this?
2. Are there any special compiler or link options I need to use?
3. Do I need to link to any other libraries?

Thanks!
