[SOLVED] Apache does not execute .fcg file

Apache does not execute .fcg file

I made the most basic fastcgi program using fastcgipp. I copied it into the /var/www/cgi-bin. I then went to /etc/httpd/conf/httpd.conf.

I replaced:

<Directory "/var/www/cgi-bin">
    AllowOverride None
    Options None
    Require all granted
</Directory>

with this:

<Directory "/var/www/cgi-bin">
    AllowOverride None
    Options +ExecCGI
    Require all granted

    SetHandler fastcgi-script
</Directory>

But when I go to localhost/cgi-bin/index.fcg, the browser prompts me to download the fcg file instead of executing it.

I am using Fedora 29.

EDIT: This is the httpd.conf

Edit: I somehow get apache to execute the script. But now, the server gives me a 500 internal error. So, I checked the error_log file. It says:

End of script output before headers

I checked my code. I had outputted the header. This is the main.cpp file:

#include <fstream>
#include <boost/date_time/posix_time/posix_time.hpp>

void error_log(const char* msg) {
    static std::ofstream error;

    if(!error.is_open()){
        error.open("/tmp/errlog", std::ios_base::out | std::ios_base::app);
    }

    error << "[" << boost::posix_time::second_clock::local_time() << "]: " << msg << "\n"; 
}

#include <fastcgi++/request.hpp>
#include <fastcgi++/manager.hpp>

class HelloWorld : public Fastcgipp::Request<char> {

    bool response() {
        out << "Content:Type: text/html\r\n\r\n";
        out << "<html><head><meta charset=\"utf-8\"></head><body>";
        out << "<p>It works!!!!</p>";
        out << "</body></html>";

        err << "Hi log!";

        return true;
    }

};

int main() {
    Fastcgipp::Manager<HelloWorld> manager;
    manager.setupSignals();
    manager.listen();
    manager.start();
    manager.join();

    return 0;
}

Solution

1) Added SetHandler fcgid-script in the <Directory "/var/www/cgi-bin"> tag in httpd.conf

2) I made a typo in the header. Replaced Content:Type:text/html with Content-Type:text/html
