Re: [cdt-dev] Suggestions for supporting debug of 64-bit PowerPC C/C++ p

[Corey Ashford <cjashfor@xxxxxxxxxx>]

Thanks for the reply, Mikhail.

I have been experimenting with using the 32-bit Eclipse + CDT on a 
64-bit program and have been pleasantly surprised that with a modified 
launch config that the debugging has so far been flawless in supporting 
both 32- and 64-bit types.

Seeing that this works well, my goal now is to change the CDT in a way 
to support debugging these 64-bit programs from a 32-bit Eclipse + CDT 
so that there is no special configuration necessary.

To this end, I've been looking at using the JNI to make a call (on 
Unix-like platforms) to the system call uname() to get the underlying 
machine type, rather than rely on the arch property that Java thinks the 
machine is.

Besides the usual cross-platform issues with the JNI, are the other CDT 
or Eclipse special considerations that I should have in mind as I work 
on this?

Thanks for your consideration
