Re: [Cppcms-users] HTTP 500 errors - backend died?

Hi,

You probably compiled cppcms library as embedded without fastcgi support.
So by default it works only as CGI. Thus you need to work with it
in different way -- configure server direcly to run cgi.

The cppcms_run script supports fastcgi and scgi backends.

How did you compile it? (flags)
