Following the instructions here (https://github.com/nbs-system/naxsi/wiki/naxsi-compile):

$ export NAXSI_VER=1.0
$ wget https://github.com/nbs-system/naxsi/archive/$NAXSI_VER.tar.gz -O naxsi_$NAXSI_VER.tar.gz
$ wget https://github.com/nbs-system/naxsi/releases/download/$NAXSI_VER/naxsi-$NAXSI_VER.tar.gz.asc -O naxsi_$NAXSI_VER.tar.gz.asc
$ export NGINX_VER=1.18.0
$ wget https://nginx.org/download/nginx-$NGINX_VER.tar.gz
$ tar vxf naxsi_$NAXSI_VER.tar.gz
$ tar vxf nginx-$NGINX_VER.tar.gz
$ cd nginx-$NGINX_VER
$ ./configure --add-dynamic-module=../naxsi-$NAXSI_VER/naxsi_src/
$ make modules

Gives the following errors:

System is fully patched. What am I missing/have done wrong?

[wargio]

can you try with the latest version also? 1.3
