I built nginx with the module ngx_ruby https://github.com/rryqszq4/ngx_ruby . When I try nginx -V or start i’m recieving error: while loading shared libraries: libruby.so.2.3: cannot open shared object file: No such file or directory. In system installed rvm 1.29.12, ruby 2.3.8p459. The libruby.so.2.3 pathes is:

/usr/share/rvm/rubies/ruby-2.3.8/lib/libruby.so.2.3
/usr/share/rvm/src/ruby-2.3.8/libruby.so.2.3
/usr/local/rvm/rubies/ruby-2.3.8/lib/libruby.so.2.3
/usr/local/rvm/src/ruby-2.3.8/libruby.so.2.3

Nginx.conf:

http {
    include       mime.types;
    default_type  application/octet-stream;
    
    set $RUBY_LIB "/usr/local/rvm/rubies/ruby-2.3.8/lib/libruby.so.2.3";

#servers configurations

        location /content_by_ruby {
            content_by_ruby "
                time = Time.now
                Ngx.print('Hello, Ngx_ruby! Current time: ' + time.inspect)
            ";
        }

Nginx version 1.26.1, OS Ubuntu 24.04 LTS

ngx_ruby code was modified according to the instructions in firs comment here: C, nginx module compilation multiple definition error

I tried add set $RUBY_LIB “/usr/local/rvm/rubies/ruby-2.3.8/lib/libruby.so.2.3”; in conf, but it’s usefull, nginx can’t load any configs. Also, I reinstall rvm, install libruby2.3_2.3.8 from deb file. Looks like nginx searching libruby.so.2.3 in concret path.
