[GiNaC-devel] Windows 64 Bit Build

[Kemlath Orcslayer]

Dear Richard,

There are quite some incompatibilities between data type lengths under UNIX and Windows therefore the standard CLN branch does not work under windows. 
I was able to port the current GiNaC to windows using CLN from "https://github.com/jrheinlaender/ginac”

If you want I have a complete GiNaC + CLN (no gmp no ams) + working example using a CMake based build system.
Its not on git since the GiNaC part is slightly modified and has some extensions for faster serialisation that I use under MPI for broadcasting. 

Let me know if you’re interested

Klaus
