Re: [ptp-dev] 32- or 64-bit Eclipse?

[Beth Tibbitts <tibbitts@xxxxxxxxxx>]

FWIW I just tried it on my mom's WinXP SP3 machine and it says

>java -d64 -version
Unrecognized option: -d64
Could not create the Java virtual machine.

>java -version
java version "1.6.0_31"
Java(TM) SE Runtime Environment (build 1.6.0_31-b05)
Java HotSpot(TM) Client VM (build 20.6-b01, mixed mode, sharing)


OK, OK, i knew it was 32 bit.  I just figure you're gathering data. :)

One question we've gotten at our tutorials is, "Should I download the 
32- or 64-bit version of Eclipse?"  I'd like to post an answer in our 
FAQ, so... is this right?  The Java command seems to work with both 
HotSpot and J9.


Q: Should I download the 32- or 64-bit version of Eclipse?

A: It depends on whether your Java Virtual Machine (JVM) is 32- or 
64-bit.  To determine this, open a terminal/command prompt and type:
     java -d64 -version

If an error message is displayed ("Running a 64-bit JVM is not supported 
on this platform."), then you have a 32-bit JVM, and you should download 
the 32-bit version

If there is no error message -- the command displays version information 
for your JVM -- then your JVM is 64-bit, and you should download the 
64-bit version of Eclipse.
