Description

I'm building a custom nginx package based on the official Fedora 23 nginx package (spec source: ​http://pkgs.fedoraproject.org/cgit/rpms/nginx.git/tree/nginx.spec?h=f23). It configures nginx like so

./configure \
    --prefix=/usr/share/nginx \
    --sbin-path=/usr/sbin/nginx \
    --conf-path=/etc/nginx/nginx.conf \
# rest of the config can be seen in the linked spec

However, /usr/share shouldn't be used for loadable modules, so I added this:

   --modules-path=/usr/lib64/nginx/modules

and changed the image_filter module to be configured as a dynamic module like so:

  --with-http_image_filter_module=dynamic

So when i install nginx, the dynamic module ends up in /usr/lib64/nginx/modules as expected.

However, when I try to load the module with:

   load_module "ngx_http_image_filter_module.so";

and then start nginx, I get this error:

nginx: [emerg] dlopen() "/usr/share/nginx/ngx_image_filter_module.so" failed (/usr/share/nginx/ngx_http_image_filter_module.so: cannot open shared object file: No such file or directory) in /etc/nginx/modules-enabled/image_filter.conf:1

It seems that --modules-path only affects installation, but isn't actually used to find and load the module

Exactly, --modules-path only affects where modules are installed. Paths in the configuration are resolved from prefix, and are expected to look like

    load_module modules/ngx_http_image_filter_module.so;

assuming default --modules-path. If you install modules into a different place, you'll have to use different paths in the configuration. Alternatively, you can consider using a symlink under the prefix to point to a correct directory.
