This is a beginners question, which I have posted to beginners@haskell.org several times, but because I have gotten no answer, I thought I would try the cafe. I'm working through the "School of Expression" book, and I would like to install the code that comes with the book somewhere. Right now I have to write my exercise programs in the same directory where the SOE code is sitting so that my exercise programs can import SOE modules. My platform is Windows. I tried using the -i options to ghc and ghci, but to no avail. It wasn't clear on Windows in what form -i takes its arguments: backslashes as usual for Windows, forward slashes perhaps? How about paths with spaces in them? Does it need quotes around the filename? I tried all combinations. ghc never gave an error indicating there was something wrong with what I typed. It happily accepted all forms of -i. But it never found the libraries. Thanks, Mike
