No .so file found

[szhu25]

HI, i don't really understand how to i dynamically use this file.

1. I download the file, config nginx.conf to add the line `load_module "/usr/lib64/nginx/modules/nginx-ct-master/ngx_http_ssl_ct_module.c";' (This is my pathway to the file as i can't find any .so file)

Then this line occured when i try to start nginx. Sep 02 15:59:03 las2 nginx[26339]: nginx: [emerg] dlopen() "/usr/lib64/nginx/modules/nginx-ct-master/ngx_http_ssl_ct_module.c" failed (/usr/lib64/nginx/modules/nginx-ct-master/ngx_http_ssl_ct_module.c: invalid ELF header) in /etc/nginx/nginx.conf:8

Did i do something wrong ?

Nginx version is 1.13.4 Openssl version is OpenSSL 1.1.0f 25 May 2017 Centos 7

Thanks.

You need to compile nginx yourself to use the module (even if you use the dynamic module - nginx doesn't support out of tree builds of dynamic modules yet).

There should be plenty of guidance on how to do this on the Internet - e.g. https://www.vultr.com/docs/how-to-compile-nginx-from-source-on-centos-7 is the first one listed in Google for CentOS 7.

You'll need to add --add-module=/path/to/nginx-ct or --add-dynamic-module=/path/to/nginx-ct to the end of the ./configure command during the build.
