GHC only statically links Haskell code. It dynamically links to GMP and the system C library and other C libs. So you're fine. On unix you can check for yourself with ldd. It lists all the shared libs that your program needs. For example: $ ldd /usr/lib/ghc-6.4.2/ghc-6.4.2 libreadline.so.5 => /lib/libreadline.so.5 (0x00002b568fca6000) libncurses.so.5 => /lib/libncurses.so.5 (0x00002b568fde3000) libdl.so.2 => /lib/libdl.so.2 (0x00002b568ff3f000) libm.so.6 => /lib/libm.so.6 (0x00002b5690042000) libgmp.so.3 => /usr/lib/libgmp.so.3 (0x00002b569019a000) libpthread.so.0 => /lib/libpthread.so.0 (0x00002b56902cf000) libc.so.6 => /lib/libc.so.6 (0x00002b56903e4000) /lib64/ld-linux-x86-64.so.2 (0x00002b568fb8e000) Duncan _______________________________________________ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
