How to use Nginx modules that are not exposed by the OpenResty port?

I

i.am.the.problem

I need to OpenResty but also need the HTTP_GEOIP2 and HTTP_REALIP modules provided by Nginx.

The Nginx port, and therefore Nginx has the configure options, for enabling these modules but they are not exposed by the OpenResty port.

How can I make this work?
 
I've tried altering the Makefile

Description    :
The libmaxminddb library provides a C library for reading MaxMind DB
files, including the GeoIP2 databases from MaxMind. This is a custom
binary format designed to facilitate fast lookups of IP addresses while
allowing for great flexibility in the type of data associated with an
address.

./configure: error: the GeoIP module requires the GeoIP library.
You can either do not enable the module or install the library.

ERROR: failed to run command: sh ./configure --prefix=/usr/local/nginx \...
===>  Script "configure" failed unexpectedly.
Please report the problem to joneum@FreeBSD.org [maintainer] and attach the
"/usr/ports/www/openresty/work/openresty-1.21.4.1rc2/config.log" including
the output of the failure of your make command. Also, it might be a good idea
to provide an overview of all packages installed on your system (e.g. a
/usr/local/sbin/pkg-static info -g -Ea).

I had no idea what OpenResty was, so I figured this was more a configuration setting, thus moved the thread to "web and network services". But now I see these are actually build options of the port itself, so I moved it back to "Ports and packages".

If you look at the option settings from www/nginx you can see the GEOIP option also adds a CFLAGS when it's enabled:
Code: 
HTTP_GEOIP2_GH_TUPLE=		leev:ngx_http_geoip2_module:3.3:geoip2
HTTP_GEOIP2_CFLAGS=		-I${LOCALBASE}/include
HTTP_GEOIP2_VARS=		DSO_EXTMODS+=geoip2
HTTP_GEOIP2_LIB_DEPENDS=	libmaxminddb.so:net/libmaxminddb

What this does, when the GEOIP2 option is enabled those CFLAGS are added. In your changes you are not setting those CFLAGS, which causes the build to fail because it cannot find the header files. The -I flag adds a search path to the compiler, it needs to be told to add the /usr/local/include directory.

You probably have to add this:
Code: 
HTTP_GEOIP2_CFLAGS=		-I${LOCALBASE}/include
 
i.am.the.problem said:
Sadly adding the CFLAG had no effect.
Click to expand...
Ok, then there's probably some more missing. We know www/nginx builds fine with the option set. So we just need to compare the settings between that and your modified version of the OpenResty port.

It's probably not going to change the outcome of the build but this should be added too:
Code: 
HTTP_GEOIP2_LIB_DEPENDS=	libmaxminddb.so:net/libmaxminddb
That will make sure OpenResty has a proper library dependency on net/libmaxminddb if that GEOIP2 option is enabled.

I'm honestly unsure what the HTTP_GEOIP2_VARS is for. That DSO_EXTMODS looks specific to the nginx build.
 
From what I can see the OpenResty port builds a bundled version of Nginx. Which includes the following file:

Code: 
cat /usr/ports/www/openrestywork/openresty-1.21.4.1rc2/build/nginx-1.21.4/src/http/modules/ngx_http_geoip_module.c

/*
 * Copyright (C) Igor Sysoev
 * Copyright (C) Nginx, Inc.
 */


#include <ngx_config.h>
#include <ngx_core.h>
#include <ngx_http.h>

#include <GeoIP.h>
#include <GeoIPCity.h>
...

The Nginx port downloads a seperate geoip module which contains the following file:

Code: 
cat /usr/ports/www/nginx/work/ngx_http_geoip2_module-3.3/ngx_http_geoip2_module.c   
/*
 * Copyright (C) Lee Valentine <lee@leev.net>
 *
 * Based on nginx's 'ngx_http_geoip_module.c' by Igor Sysoev
 */


#include <ngx_config.h>
#include <ngx_core.h>
#include <ngx_http.h>

#include <maxminddb.h>
...

So the bundled Nginx code from OpenResty is using the discontinued GeoIP database rather than the GeoIP2 database. The libmaxminddb provides the api for the GeoIP2 database.
