@itpp16 Because you didn't provide enough info, I can only guess here. This error message means two possibilities usually:

  1. You didn't compile the ngx_http_lua module as a static module into your nginx binary while ngx_http_lua_upstream_module depends on it, or
  2. You did compile the ngx_http_lua module as a dynamic module but you did not compile ngx_http_lua_upstream_module as a dynamic module at the same time (which is required here). The ngx_http_lua_upstream_module does not support building as a dynamic module (yet) BTW.

Everything is build as static, nothing new other then the new 1.9.12 layout and "--add-module=" as before.

@itpp16 It cannot be. The _ngx_http_lua_get_request symbol is from ngx_http_lua_module and apparently your linker cannot find it due to the lack of ngx_http_lua_module. The same applies to _ngx_http_lua_add_package_preload.

and confirmed, all openresty modules work when using the previous (lua-nginx-module) config file
