undefined symbol: lua_rotate

[satscreate]

I had done below steps, downloaded lua-cjson-2.1.0.7 from this repo,

make install
mkdir -p /usr/local/lib/lua/5.1
rm -f /usr/local/lib/lua/5.1/cjson.so
cp cjson.so /usr/local/lib/lua/5.1
chmod 755 /usr/local/lib/lua/5.1/cjson.so

Then, sudo systemctl restart nginx.service

Error:

2020/02/19 06:59:52 [error] 29524#29524: *1 lua entry thread aborted: runtime error: error loading module 'cjson' from file '/usr/local/lib/lua/5.1/cjson.so':
        /usr/local/lib/lua/5.1/cjson.so: undefined symbol: lua_rotate
stack traceback:

What am i missing!!!!

Are you sure? This repo has no "lua_rotate" call at all on the master branch. You can try grepping the word "rotate" yourself.

And there's no lua_rorate symbol in LuaJIT. It seems to be part of the Lua 5.3 ABI.

Yes am sure about it. it gives this error when i try to start nginx with below setup,

access_by_lua '
         local opts = {
           redirect_uri_path = "/redirect_uri",
           accept_none_alg = true,
           discovery = "http://www.example.com:8080/auth/realms/NGINX/.well-known/openid-configuration",
           client_id = "nginx",
           client_secret = "62d3b835-e3d1-4cec-a2f2-612f496bc6c3",
           redirect_uri_scheme = "http",
           logout_path = "/logout",
           redirect_after_logout_uri = "http://www.example.com:8080/auth/realms/NGINX/protocol/openid-connect/logout?redirect_uri=http://www.example.com/",
           redirect_after_logout_with_id_token_hint = false,
           session_contents = {id_token=true}
         }
         -- call introspect for OAuth 2.0 Bearer Access Token validation
         local res, err = require("resty.openidc").authenticate(opts)
         if err then
           ngx.status = 403
           ngx.say(err)
           ngx.exit(ngx.HTTP_FORBIDDEN)
         end
      ';
      # I disabled caching so the browser won't cache the site.
      expires           0;
      add_header        Cache-Control private;
      location / {
      }

With this setup this seems error ed out with this exception

@satscreate Your cjson.so was compiled against the Lua 5.3 interpreter's header files I believe. You should try our OpenResty instead to avoid such things (lua-cjson is part of the OpenResty build):

How can i compile against this version or lower version,

[root@sample ~]# lua -v
Lua 5.3.3  Copyright (C) 1994-2016 Lua.org, PUC-Rio

And below way am actually adding lua path in nginx.conf: lua_package_path "/usr/local/lib/lua/?.lua;;";

Since am interested in compiling modules by own and apply on top if nginx so. can you please help me on steps to resolve the same without actual openresty installation. because openresty itself comes with own nginx version which am not going to utilize so.

[agentzh]

@satscreate I said the easiest way is to use OpenResty directly. If you really want to compile lua-cjson yourself, you'll have to fiddle with the Makefile variables to point the header file path to OpenResty's LuaJIT header file directory.

[agentzh]

The biggest point of OpenResty is to avoid such things in the first place.
