This is something I just noticed...

hello.hs: module Main(main) where

main = putStr "Hello world!\n"

hello.c: #include

int main(void) { printf("Hello world!\n"); return 0; }

[abe@shiva:~/src/test] $ ghc hello.hs -o hello_hs [abe@shiva:~/src/test] $ gcc hello.c -o hello_c [abe@shiva:~/src/test] $ ls -l hello_* -rwxr-xr-x 1 abe engy 13712 Jul 18 11:34 hello_c -rwxr-xr-x 1 abe engy 299900 Jul 18 11:33 hello_hs

Why is the binary made by ghc 20 times bigger than the one made by gcc?

I don't know for certain, but I've got a couple of guesses:

1. hello_hs is probably statically linked. hello_c is probably dynamically linked.

Right. The ldd command gives the dependencies (on Linux): awo@asterix:~> ldd hello libc.so.6 => /lib/libc.so.6 (0x40022000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000) If you compile hello.c as static binary, like gcc -static -o hello hello.c then the resulting exe is rather big, too ;-) awo@asterix:~> ls -l hello -rwxr-xr-x 1 awo users 1486299 Jul 18 21:40 hello So ghc isnt so bad, really :-) Greetings Andreas
