[Haskell-cafe] little help please

[Roderick Ford]

Yes, THANKS!! But my other problem was, that once I get it to compile, I get nothing output:
C:\Program Files\MySQL\bin>ghc --make -o mysql_config.exe main.hs[1 of 1] Compiling Main             ( main.hs, main.o )Linking mysql_config.exe ...
C:\Program Files\MySQL\bin>mysql_config --libs
C:\Program Files\MySQL\bin>mysql_config --goob
C:\Program Files\MySQL\bin>pwhich mysql_config.\mysql_config.EXE
... yet instead, I should be getting this:
C:\Program Files\MySQL\bin>..\scripts\mysql_config.pl --libs"C:\Program Files\MySQL/lib/mysqlclient.lib" "wsock32.lib" "advapi32.lib" "user32.lib"
C:\Program Files\MySQL\bin>..\scripts\mysql_config.pl --goobUnknown option: goobUsage: C:\Program Files\MySQL\scripts\mysql_config.pl [OPTIONS]Options:        --cflags         ["-IC:\Program Files\MySQL/include/mysql" "-D_WINDOWS""/MT" "/Zi" "/O2" "/Ob1" "/D" "NDEBUG" "-DDBUG_OFF" "/wd4996"]        --include        ["-IC:\Program Files\MySQL/include/mysql"]        --libs           ["C:\Program Files\MySQL/lib/mysqlclient.lib" "wsock32.lib" "advapi32.lib" "user32.lib"]        --libs_r         ["C:\Program Files\MySQL/lib/mysqlclient.lib" "wsock32.lib" "advapi32.lib" "user32.lib"]        --socket         [/tmp/mysql.sock]        --port           [0]        --version        [5.1.45]        --libmysqld-libs ["C:\Program Files\MySQL/lib/mysqlserver.lib" "wsock32.lib" "advapi32.lib" "user32.lib"]
... so, it looks like I am handling the IO wrong, or else I go directly to the exitWith instead of returning the IO from "return".  So, I suppose this is normal behavior, but how do you do BOTH.  I guess I should actually be "print"ing the output rather than returning it, then doing the exitWith.
