World: r4wp

do you have the r3-make.exe in the make/ dir?

also make sure you are using the mingw32 makefile and not the Linux 
one

Yes yes, but there is some special option when I launch "mingw32-make 
prep" ??

r3-make must me r3-make or r3-make.exe?

(must be)

well, it depends what you have in the makefile, see the REBOL variable

r3-make -qs

so should it  be named just "r3-make"?

If you are under windows I'd prefer the .exe suffix ;)

I noticed another variable: TO_OS
what does it mean?

To me it looks you are using some Linux version of the makefile

because TO_OS= TO_LINUX

Is there another make file?

Where?

Is not corss-platform in the make directory?

Well, to save you some time you should get the R3 form repository 
either from Andreas or me on github. These repos are work in progress 
for Win/mingw at the moment (maybe others have simmilar repos as 
well)

The Win32 build changes have already been merged into Carl's repository 
as well.

r3 form=r3 fork

(The first set of them, that is.)

Ok, I'll try your forks. Thanks

If you have TO_OS=TO_LINUX, then you need to generate a Win32 makefile 
first.

How?

make make OS_ID=0.3.1

Then:
make prep
make

Andreas, ah, good,,but I think Max will still need some tweak to 
bea bel to build...or are the merged changes functional at least 
to get the basic core version?

Yes, they are.

cool

Full set of our changes, except for the dropping of NM.

great, so yes, go for the official repo ;)

Rebol System error 1405...

Ah, that sounds like the Win7 crash.

WinXp

During make make already, I guess?

Try running make make directly:
./r3-make ../src/tools/make-make.r 0.3.1

That should give you the Win32 makefile, with a workaround for the 
crash in place.

to launch an exe, it must and wth .exe in WinXp (from console)

Ok, launched the make make

Error:

./r3-make -qs >NUL: ../src/tools/make-headers.r
.
 non è riconosciuto come comando interno o esterno,
 un programma eseguibile o un file batch.
mingw32-make: *** [prep] Error 1

make make OS... is ok
make prep gives that error

Is like that says: 
.
 is not a command

problem is in CD=./

it doesn't work on windows

it should probably: "CD=cd"
it returns the current path on Windows.

CD = %CD%  
works

so I arrive at the next bug...

C:\DOCUME~1\max\DOCUME~1\GitHub\r3\maker3-make
 is not recognized

is the path correct? maker3-make is an executable? if so it should 
be maker3-make.exe.

It doesn't exist any maker3-make

anywhere

If you can build successfully R3 in Widnows with MinGW, please post 
the procedure on GitHub wiki
