Re: [Rlib-devel] Patches for compiling on Windows

[Zoltan B. <zb...@du...>]

Hi,

this seems to be the last thing needed for Windows, so it not only
compiles but also produces correct results. :-)

While using a report that summed up large numbers and the result
was larger than 2^31, I got negative results, but only if the app and
RLIB was running on Windows. Under Linux, it worked correctly.

It turned out the problem is that %lld is interpreted as %ld under
Windows. Browsing through inttypes.h in MinGW revealed that
the correct printf format is I64d for Windows.

So, I fixed it by killing all "%lld" occurences and replaced them
with the portable format string. I also killed the _64BIT_ definition
in configure.in because it's not needed anymore.

After recompiling RLIB with this patch I get correct results in Windows.

Best regards,
Zoltán Böszörményi
