However I do of course want to run it through CGI on a webserver. I'm running lighttpd. If I try to run the file compiled above I get "500 - Internal Server Error", most likely since the enviroment is not correct for dynamic linked files:
Why wouldn't the environment (i.e. available dynamic libraries) be correct for the web server?
Hence I wanted to use static linking ( http://www.haskell.org/haskellwiki/Web/Literature/Static_linking ). However trying to compile using the "-optl-static" option fails: There are two main categories of error messages above:
1 : ...requires at runtime the shared libraries from the glibc version used for linking
Yes, Linux (or rather, glibc) doesn't really support static linking any more, and relies on hard-coded paths to libraries for unicode stuff and name resolution and authentication. You can override this with environment variables, though. Perhaps this is helpful: http://blog.malde.org/index.php/2010/05/22/snagged/
2a : undefined reference to `pthread_....'
2b : undefined reference to `pthread_mutex_lock'
ghc ... -optl-static -optl-pthread ^^^^^^^^^^^^^ Not sure why you have to add this manually, but it's been this way for years - at least since ghc 6.8, I think. -k -- If I haven't seen further, it is by standing in the footprints of giants
