If I do it from cmd, a blank line appear, but the prompt appear again.
Can you try running scripts at least, for example
echo 2 printNl > testscript.st
gst testscript.st
The problem might be in the interface to the Windows console. Don't
know for real though, I guess I really have to find someone who lends
me a Windows machine for a while...
I did a make clean, and compiled again. The "make check" works until
intmath.st, and then freeze. I cancelled after 4 minutes aprox.
That's not a problem. You are using Smalltalk LargeIntegers (not
primitives) and that's very slow. Don't worry about that.
