ngx_stream_js_module.so: undefined symbol: ngx_stream_core_module

[centminmod]

With Nginx 1.23.0 and njs 0.7.5 I am getting

nginx -t
nginx: [emerg] dlopen() "/usr/local/nginx/modules/ngx_stream_js_module.so" failed (/usr/local/nginx/modules/ngx_stream_js_module.so: undefined symbol: ngx_stream_core_module)

but revisiting https://nginx.org/en/docs/njs/install.html I notice it says or and not and when loading the module

After package installation, njs dynamic modules need to be loaded with the load_module directive:

load_module modules/ngx_http_js_module.so; or

load_module modules/ngx_stream_js_module.so;

so I only need to load one of them and not both?

I've been loading both fine with njs 0.7.4/0.7.5 and nginx 1.21.6 or 1.22.0

load_module "modules/ngx_http_js_module.so";
load_module "modules/ngx_stream_js_module.so";

So only need load_module "modules/ngx_http_js_module.so"; ?

On CentOS 7.9 64bit with GCC 10.2.1

Hi @centminmod,

If you do not use stream js module you have to load only ngx_http_js_module.so

[xeioex]

@centminmod

[emerg] dlopen() "/usr/local/nginx/modules/ngx_stream_js_module.so" failed (/usr/local/nginx/modules/ngx_stream_js_module.so: undefined symbol: ngx_stream_core_module)

While I see that you provide --with-stream while building the modules, the most straightforward reason for the error is that the nginx binary you are using with njs module is not built with stream subsystem. Cannot reproduce so far.

@xeioex thanks for that insight - believe I see what I did wrong - I have a nginx version check for enabling stream module but forgot to add a check for nginx 1.23!
