[mapserver-users] mapserver files to subdomain results in '500Internal Server Error' when mapserv executable accessed through url

[Ted Spradley]

Thanks Steve.

I added SetEnv LD_LIBRARY_PATH /usr/local/lib to /etc/httpd/conf/httpd.conf
as follows:
<Directory "/var/www/cgi-bin">
    AllowOverride None
    Options None
    Order allow,deny
    Allow from all
    SetEnv LD_LIBRARY_PATH /usr/local/lib
</Directory>

and restarted Apache, but I know I am only guessing.  No success.

Then I tried setting the environment variable by adding 'SetEnv
LD_LIBRARY_PATH /usr/local/lib'
to the /var/www/vhosts/domain/conf/httpd.include file as follows:

<VirtualHost xxx.xxx.xxx.xx:80>
        ServerName   maps.domain.com:80
        SuexecUserGroup         snoogadmin psacln
        ServerAdmin  "admin at domain.com"
        DocumentRoot /var/www/vhosts/domain.com/subdomains/maps/httpdocs
        CustomLog  /var/www/vhosts/domain.com/statistics/logs/access_log
plesklog
        ErrorLog  /var/www/vhosts/domain.com/statistics/logs/error_log
        ScriptAlias  /cgi-bin/ /var/www/cgi-bin/
        SetEnv LD_LIBRARY_PATH /usr/local/lib

and restarted Apache, but with the same result of '500 Internal Server
Error'.

Possibly I need to be entering different parameters into the LD_LIBRARY_PATH
variable?

Thanks again,
Ted S
