I'm trying to use Network.FastCGI with Apache2, but running into an error.
I'd like to believe that the web server is configured correctly, because I
can successfully view the following, compiled to <web
root>/fastcgi/test.fcgi:
#include <fcgi_stdio.h>
int main(void){
int count = 0;
while(FCGI_Accept()>=0){
printf("Content-Type: text/html\r\n");
printf("\r\n");
printf("Hello, World: %d", count++);
}
return 0;
}
Now I compile Fcgi.hs to <web root>/fastcgi/test2.fcgi:
import Control.Concurrent
import Network.FastCGI
action :: CGI CGIResult
action = do
setHeader "Content-type" "text/plain"
tid <- liftIO myThreadId
output $ unlines
[ "I am a FastCGI process!"
, "Hear me roar!"
, ""
, show tid
]
main = runFastCGIConcurrent' forkIO 10 action
When I view localhost/fastcgi/test.fcgi, I get the hello world page, but
attempting to view test2.fcgi shows an 'Internal Server Error" in firefox.
The apache error log says:

I've tried Fcgi.hs with two different sample FastCGI programs with the same
results. Any suggestions?
