Compiling under Windows? about selfie

[nubok]

So I will work on writing a Makefile for Windows that can be used with nmake.

[ChristianMoesl]

On Windows we usually use a Linix environment like msys2 and gcc or clang as compiler. For the Visual C++ compiler and PowerShell, you need to install make and modify the Makefile to match the available compiler options.

As promised I created a pull request that might not be perfect, but at least allows selfie to compile using Visual Studio 2017/nmake: #31

Note that one (two?) of the tests currently fail under this configuration. I am not in the position to be able to find the reason for this test failure.

[ChristianMoesl]

Great! I'm working on this Problem already. It has something to do with the hypster starting on boot level zero.

If your are interested in it, PR #32 fixes this bug on Windows (commit).

For testing I merged the ChristianMoesl:vpage-size branch with my Makefile.win changes. To make this result reproducable I created a new patch "vpage_win" for this experiment and uploaded it:

(EDIT: also cf. https://github.com/cksystemsteaching/selfie/network).

The results are "interesting":

> selfie.exe -c selfie.c -o selfie3.m -s selfie3.s -y 3 -l selfie3.m -y 2 -l selfie3.m -y 2 -c selfie.c -o selfie4.m -s selfie4.s

now works:

But on the other hand

[ChristianMoesl]

I changed the Makefile in my PR! The command should look like
./selfie -c selfie.c -o selfie5.m -s selfie5.s -min 8 -l selfie5.m -y 2 -l selfie5.m -y 2 -c selfie.c -o selfie6.m -s selfie6.s
This is needed because the page table size in selfie increased dramatically.

[nubok]

I tried it out: This change indeed fixes the problem. In other words: After this patch nmake -f Makefile.win all ran all through without any abnormalities visible to me. So I merged this into "my" vpage_win branch:

We will stay with the the combination of a Unix subsystem (msys2/cygwin) with gcc/clang as toolchain for windows users.
