Kelly: I have always found using gcc with IDL on Windows to be a
difficult endeavor. Also, the use of make_dll is optional and in the
past has made life more difficult rather than easier. I suggest
grabbing the free edition of Visual Studio Express and creating the
dll this way. Just remember to export the functions you will be
accessing from IDL. This is definitely an advanced topic, so start
with the simple examples in the external directory of the IDL distro.
