Dynamic module undefined symbol ngx_stream_get_variable_index problem #48

Open modestas0326 opened 3 years ago

modestas0326 commented 3 years ago

Hello, I can't launch your dynamic module with my nginx, tried using prebuild modules & build my own, but the problem persists.

After build steps

  1. Move objs/ngx_http_accounting_module.so to /usr/lib64/nginx/modules/ngx_http_accounting_module.so
  2. Load my module from config like this: load_module "/usr/lib64/nginx/modules/ngx_http_accounting_module.so";
  3. call nginx -s reload

Error

nginx: [emerg] dlopen() "/usr/lib64/nginx/modules/ngx_http_accounting_module.so" failed (/usr/lib64/nginx/modules/ngx_http_accounting_module.so: undefined symbol: ngx_stream_get_variable_index) in /usr/share/nginx/modules/mod-http-accounting-module.conf:5

Any suggestions? Thank you.

Can't reproduce. Works fine here. NGINX (mainline) 1.19.7, however.

modestas0326 commented 3 years ago

Questions

  1. Can you provide with what configuration did you compile the module?
  2. Did you check with 1.16.1 nginx version?
  3. Can you provide your compiled .so file to download for 1.16.1?

Thank you for your time looking into this.

modestas0326 commented 3 years ago

Hey, I tried to build an Nginx 1.16.1 from source without any custom modules by this guide step-by-step: https://medium.com/@yildirimabdrhm/nginx-is-an-open-source-web-server-software-designed-to-use-as-a-web-server-reverse-proxy-http-7e0cd0bab12

Unfortunately, your module returns the same error on load, it just won't work, can you look again at this?

Sincerely, Modestas

I got the same problem, nginx version 1.20.2.
