Having a need to do high-precision calculations in both Linux and Windows, I've ported cln and ginac to Windows, and I thought it'd be appropriate to share the results. (I've been using cln for a couple of years now, and I'm deeply impressed with it. I haven't yet gotten far into ginac, but it's something that I'd also like to support.) I have: 1) A 47MB zip file, containing - the gcc compiler, ported under mingw, along with the gmp and cln libraries - the notepad++ editor - a batch file that allows notepad++ to be used as a simple ide 2) A 69MB zip file containing all of the above, plus the ginac libraries. 3) A rather detailed summary of the process used to assemble the above. When unzipped, the resulting code can be used on any Windows machine without the need for installation or presence of cygwin (it will even run directly from a CD). This will make cln and ginac accessible to a wider audience, which is why I thought it'd be a good idea to share it. It makes sense to have these files hosted on the official ginac/cln site. Any suggestions about who I should contact to make arrangements? Thanks! Mike Miller
