It looks like it's broken since nginx-1.20.2, they change a lot of SSL functions. Let me see how to solve it.

Getting similar errors with all recent nginx versions I've tried, 1.24, 1.22, 1.20, and 1.18, building on AlmaLinux 8.

Old server had make version 3.82. New server has make version 4.2.1. I believe the compile errors in the original post might be related to newer versions of make.

If I set an environment variable to export CFLAGS="-Wno-error=implicit-fallthrough" then I am able to get further, but the build still stops with the following error:

In file included from src/event/ngx_event_openssl.h:17,
                 from src/core/ngx_core.h:84,

ChatGPT seems to think that it's related to an incompatible version of openssl. Interestingly on my old server I had 1.0.2k-fips 26 Jan 2017 installed. New server has 1.1.1k FIPS 25 Mar 2021

Any help with these issues @yaoweibin ?
