Re: [e4-dev] Cant't compile current e4 trunk

Hi Tom,

I realized working with the fragment was a pain but I didn't know this about 64 bit, ugh.

My suggestions were genuine though, if people believe there's another route we should take.

Regards,
Kevin

Hi Kevin,

The problem with your fragment is that setting up SWT for a 64 bit
system is a bit more work than simply checking out from CVS.

It involves the conversion of all Java-Files from int to long. I
couldn't find a way to make this work smoothly without some custom
interaction with the sources:

a) Check out org.eclipse.swt
b) Rename .classpath_cocoa to .classpath
c) Check out org.eclipse.swt.cocoa.macosx.x86_64
d) Run build.xml in x86_64
e) Copy the transformed *.java back to org.eclipse.swt

Without doing steps d) and e) you get a the error message from Java that
you are trying to load 32bit libs into a 64bit vm although the libs you
are trying to load are in reality the x86_64 that int's on the Java-Side
provide get you into trouble.
