Hi,
I developed an application and it runs perfectly over X86. However, when
i try to run it on ARM it stops reading shapefiles (actually it reads
wrong coordinates). I wrote a simple program to tell just the first
"point" coordinates.
On X86:
x=: -53.1275 y= -31.8682
On ARM:
x=: -1.00226e-13 y= -1.76938e+52
Looking for the problem here, i found a thread from Etienne Dube on
(2004-04-07 05:12:55 GMT), saying it's a byte ordering problem.
"Each 32-bit word in the 64-bit double value is stored little-endian,
but the most significative 32-bit word comes last in memory
("big-wordian")."
Changing the word-order for the first feature inside the ".shp" ("11 36
3c bd 52 90 4a c0" to "52 90 4a c0 11 36 3c bd") and running it again:
under X86:
x=: -1.00226e-13 y= -31.8682
under ARM
x=: -53.1275 y= -1.76938e+52
So, clearly, i have the same problem then Etienne. He sent a patch, but
didn't made many tests...
Is there a "final"solution for the problem? I couldn't see any answer to
him.
Regards,
Adriano
