Ring CGI Error on ubuntu 17.04 , appache2

[Salama Ashoush]

Hello Mahmoud

this log from my appache error.log

AH01215: (8)Exec format error: exec of '/var/www/cgi-bin/hw.ring' failed: /var/www/cgi-bin/hw.ring

[Mon Oct 09 14:38:09.742225 2017] [cgi:error] [pid 4312] [client 127.0.0.1:54338] End of script output before headers: hw.ring

here is my steps:

1. configure appache to run cgi scripts and test it with other scripts like perl 
   
2. created a file with this code in my cgi-bin dir:
   

#!/usr/bin/ring -cgi
See "content-type : text/html" +nl+nl+
"Hello World!" + nl

when try to run the code with ring from the terminal it runs and output the text 

extra : i wonder if there any other way or plans for web development rather than cgi  ( built in server like python or other web languages )

Hello Mahmoud

Finally i found the solution

here is my steps:

1. configure Apache server to run cgi scripts /etc/apache2/conf-enabled/serve-cgi-bin.conf 
    

1. <IfModule mod_cgi.c>
            Define ENABLE_USR_LIB_CGI_BIN
</IfModule>


<IfModule mod_cgid.c>
           Define ENABLE_USR_LIB_CGI_BIN
</IfModule>
     
<IfDefine ENABLE_USR_LIB_CGI_BIN>
       ScriptAlias /cgi-bin/ /var/www/cgi-bin/
       AddHandler cgi-script .cgi .ring
        <Directory "/var/www/cgi-bin">

1. 
             AllowOverride All

1. 
             DirectoryIndex index.cgi index.html index.ring
             Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
             Require all granted
         

1. </Directory>
</IfDefine>
</IfModule>

   
   
   
2. make sure you cgi folder has the right owner  
   sudo chown $USER:www-data /var/www/cgi-bin/
   
   
3. create .ring file in your cgi folder and give it execute permissions
   sudo chmod 755 hw.ring
   
   
4. write your code with this shebang on top of the file
   #!/usr/bin/env ring
   
   
6. hello world test 
   #!/usr/bin/env ring
   see "content-type: text/html"+nl+nl
   see "hello world!" + nl
   
   
7. if you need to use web lib copy the file to you cgi folder and give it execute permissions the load it to your code and have fun
   #!/usr/bin/env ring

   
   

   Load "weblib.ring"

   Import System.Web

   
   

   New Page

   {

           Text("Hello World!")

   }
8. go to
   localhost/cgi-bin/yourfile.ring
   to test your code

thanks mahmoud ,

i hope someday ring will have built in web-server it will be very nice

Best Regards

Hello Salama

I agree with you, We should have a Web Server + Advanced Web Framework in the future.

Keep up the good work :D
