duplicate geoip variable

[cortex3]

Hi, I'm a little lost here.
I switched from nginx plus with geoip2 to a self compiled nginx with geoip2.
The config stayed the same but now I'm receiving the following error:

[root@approuter-stg-01 ~]# nginx -t
nginx: [emerg] the duplicate "geoip_country_code" variable in /etc/nginx/nginx.conf:106
nginx: configuration file /etc/nginx/nginx.conf test failed

This is the code it is referring to in the error:

  geoip2 /usr/share/GeoIP/GeoLite2-Country.mmdb {
        auto_reload  1h;
        $geoip_country_code  country  iso_code;
        $geoip_country_name  country  names  en;
    }

If i remove the country_code line it will produce the same error for the country_name line.
The file exists and geoip2 was installed properly.

packages:

[root@approuter-stg-01 ~]# yum list installed | grep -e max -e geo
geoipupdate.x86_64               4.5.0-1                    @/geoipupdate_4.5.0_linux_amd64HF4dad

I can reproduce the error on a fresh centos 7 system with the same package and the default config (+ the geoip config)

[root@freshsystem ~]# nginx -t

To compile my rpm I used Version 3.3. of your module and libmaxminddb-1.4.3.

It would be fantastic if you could give me any pointers here, since I have no idea how to debug this further.

You're compiling in both the geoip and geoip2 modules. The geoip module already reserved geoip_country_code, so you can't use that for geoip2.
