Are there any plans to to prooduce gnuplot executables for
- Windows 7 x64 (which should run on Windows 8 x64 Desktop) ?
- Windows 8 Metro Style App ?
- Windows 8 RT Metro Style App for ARM tablets ?
Tatsuro Matsuoka tried to do 64 bit build a while ago, but I do not know if he succeeded. Are you saying that Windows 8 will require a 64 bit version? Right now, I am using the 32 bit version on an Win7 x64 machine without a problem.
As for the Metro style apps, I am not aware of anybody working on this.
Microsoft claims, that any Win7 (x86 and x64) program will run on Win8 desktop.
However Win8 Metro style is the preferred application type because it supports touch screens which will be common place soon.
So Win8 desktop will soon be something like the DOS-Box in Win7 (a toy for old unix hackers).
With x86 and x64: as most new consumer PCs nave more than 4GB, x64 is an natural choice. I used Visual C++ 2010 Express to port several applications from x86 to x64 without any problem, but may be gnuplot contains some functions which depend on a specific word size.
Gnuplot has been running on 64-bit systems since the early 90s. So no problem there.
Several people have reported running gnuplot on ARM, but there is not a specific ARM build target in the current configure scripts.
Metro - no idea
It is more about compiler support and the availability of third party libraries. MSVC does still not support union initializers, and therefore "objects" require an additional patch. Mingw64 on the other hand currently lacks the gdiplus library (at least the last time I looked). I also vaguely remember problems with wxWidgets 2.8.12 and Mingw64, while, I think, there are still issues with gnuplot and wxWidgets 2.9.x....
So were close, but no quite there yet. A 64bit build is not very high an my personal agenda. So your help and expertise would be more than welcome.
Metro support might be a worthwhile project - once MSVC 2012 and Windows 8 are out and we get out hands on them. (Although, I have doubts about just how quickly this transition to Metro will take place given the huge number of XP, Vista and 7 installations.)
Win64 is now supported for 4.6 and 5.0. You can find 64bit binary builds from current CVS at various places:
Moreover, there has been an anouncment on work on a WinRT version:
