I just received and installed my copy of Windows 7 Ultimate. Pretty slick.
I went with the 64 bit version. It seems to be what most people out
there have installed. Plus, I figured it would be the most
problematic, so I may as well get ready to deal with the potential
bugs.
So far I''ve had 1 bug with sys-uname (already fixed).
I decided to give win32-api a shot:
win32/api.c:565: warning: cast to pointer from integer of different size
default:
rb_raise(cAPIProtoError, "Illegal prototype
''%s''",
RSTRING_PTR(a_proto[i])
);
I''m not sure I understand the warning in this case. Anything I need to
be worried about?
The larger problem so far is that rm.exe (of all things) from msys is
stackdumping.
Regards,
Dan

On Windows 64bit, data size is: sizeof(char) = 1 sizeof(short) = 2 sizeof(int) = 4 sizeof(long) = 4 sizeof(float) = 4 sizeof(double) = 8 sizeof(void*) = 8 sizeof(size_t) = 8 For detail, refer to http://msdn.microsoft.com/en-us/library/aa505945.aspx The whole win32utils assumed sizeof(long) = sizeof(void*) = 4. Thus, win32utils package is compatible with 32 bit. Another win64utils is required for 64 bit :) Regards, Park Heesob

Is there anything we can do to make win32-api work on 64 bit windows? There is check_sizeof in mkmf.rb, if that helps at all. Regards, Dan

(yeah, the joys of WOW64) I think mkmf one will work for you, since will use the same compiler used by Ruby in the same compilation mode, so will generate the expected sizeof.

And I''m seeing rm.exe segfault there as well. Can you confirm? Regards, Dan PS - What''s happened to mingw.org?
