I live in China, and I want to run a vpn through vtun，When I compile, I get the following error
/home/HouXinLin/projects/vpn/vtun-3.0.3/main.c:142: undefined reference to `clear_nat_hack_flags'
My version
GCC： gcc version 12.2.0 (GCC)
OpenSSL :OpenSSL 3.0.7 1 Nov 2022 (Library: OpenSSL 3.0.7 1 Nov 2022)
vtun： 3.0.3
I can't find the answer I want through Google
