Eng student? Fantastic! What discipline? Are you studying at Vic, Auckland or Canterbury?
I am also running Windows 7, 64 bit.
I use programmer's notepad
which suits me. You can use your favourite.
The compiler I use is MinGW 32 bit with version 3.4.2. For some reason this works well. This is stored under C:\MinGW\
Then I use the makefile that comes with the source, and the settings as per http://www.attnam.com/topics/1193/How_to_compile_CLIVAN_chal...
In fact the set-up to compile CLIVAN is the same as for IVAN CVS.
If you can get your hands on Microsoft Visual C++ (or Code::Blocks) and open IVAN as a project, you can use the search functionality for extremely rapid sourcediving, which is great if you want to copy paste some code funtions to make something really wierd and novel, like a fire-breathing bat.
